What? You were expecting more?

To be honest, the mass of knowledge that may (or may not) be contained in this post is mostly summed up and contained in that single sentence. The basic jist of this is going to be: abuse limpers at every opportunity. I'll get into some reasoning, some math, some examples, but I want you to keep in mind that basic premise: limpers suck at poker and have hands they are unsure about.

LIMPERS SPECULATE

Everyone's limping range is different. Some people will never open-limp. Some will open-limp with AKs because "its a drawing hand". Some will limp with KK to trap you. Some limp with small pairs to setmine on the cheap. Some limp any two cards because they want to see a flop, any flop. But the basic premise behind limping is the same: speculation.

The idea is to see a flop for cheap, then make a lot of money afterward when you spike. Thinking players describe this as Implied Odds, or IO. IO is when your hand is not strong enough to play at the current price, but the implied profit from later streets if you hit makes the hand playable.

Its unlikely many limpers will describe their play with the term however. Why? Because there's tons of information available on poker strategy readily available. Books, twoplustwo and other forums, DeucesCracked and other coaching sites, etc. And all of them will generally recommend against open limping. Therefore, when you see someone open-limp, and more people limp along behind, its likely that these players have not availed themselves of these resources. In other words, its unlikely they have studied the game, and likely that they are weak players.

Now, its such common knowledge that limping is bad that isolating limpers is much less valuable than in years past; there's just not that many people happily limping along in every pot anymore. But if there's one place where you still find the limpers, its at the micro-stakes tables, and this is the microstakes forum after all. So keep in mind that some of this advice may not be as useful as you move up (and may even get you in trouble), but let's take a look at the HUGE opportunity for profit in isolating limpers.

POSITION

Let's start by looking at some reasons to isolate limpers. Poker is a game of edges - you want to find and edge and press it. An edge can be knowing you opponents tenancies and exploiting them (what alex23 calls "skill edge"). An edge can be in hand strength (being ahead of their range). An edge can be having position on your opponent. If you don't understand how valuable position is and how to use it to your advantage, I suggest you study up with CaptVimes .

One of the key advantages you gain in isolating limpers is a positional advantage. This works in a couple ways. First, the folks you know are interested in seeing a flop and playing a hand (the limpers) have already acted, and you have relative position on them. Second, it makes it more difficult for players who have absolute position on you to play the hand, and makes it much more likely that you will have position on the field post flop. Let's look at one (admittedly contrived) example.

Assume full stacks and unknown villains, 25nl. Hero is on your left and is a 15/12 TAG.

Pre Flop: ($0.35) Villain is BU with A9
3 folds, MP1 calls $0.25, 1 fold, Hero calls $0.25, Villain ???

How does he feel about his hand here? Pretty good ya? He'll play it, and just has to decide to limp along or raise it up. But what about:

Pre Flop: ($0.35) Villain is BU with A9
3 folds, MP1 calls $0.25, 1 fold, Hero raises to $1.25, Villain ???

How does he feel about his hand NOW? Not so warm and fuzzy, eh? He'll need to spike to be good, plus there a lot of RIO because a ton of Hero's range is aces with a better kicker. Fold! Do you see how Hero just got postflop position on EVERYONE left in the hand by isolating the limper and pushing the button out? Let's peel back the curtain:

Pre Flop: ($0.35) Hero is CO with Q J
3 folds, MP1 calls $0.25, 1 fold, Hero raises to $1.25, 3 folds, ...

You just got the in-position player to fold the best hand FTW.

Isolating limpers gets you better postflop position in bigger pots. Its usually better than limping along, and often also better than folding. Isolating limpers presses your positional edge.

INITIATIVE

Again, I'm not going to explain why initiative is good, but in 3 weeks when Cangurino writes his Concept of the Week article you can read all about it. Suffice to say, initiative is money in the bank. Let's just continue with the same example, eh?

Pre Flop: ($0.35) Hero is CO with Q J
3 folds, MP1 calls $0.25, 1 fold, Hero raises to $1.25, 3 folds, MP1 calls $1.00

Flop: ($2.85) T A 8 (2 players)
MP1 checks, Hero bets $2.25, MP1 folds.

Results: Hero wins pot $2.85, profits $1.60.

And peel back the curtain:

Pre Flop: ($0.35) Villain is MP1 with 3 3
3 folds, MP1 calls $0.25, 1 fold, Hero raises to $1.25, 3 folds, MP1 calls $1.00

Flop: ($2.85) T A 8 (2 players)
MP1 checks, Hero bets $2.25, MP1 folds.

OHAI you just won 6+bb with the worst hand!

Isolating limpers will get you initiative in a hand, and initiative is almost as good as cash most places. Always use your initiative to cbet limp-callers. Remember, they are unsure about their hands. They don't want to play! Give them a reason not to.

And when they do start putting money in the pot, get out. Obv if MP1 calls or c/r here you shut down to an offsuit-K on the turn. But guess what? He expects you to have TP, and if he starts putting money in the pot, he's got TP beat. If you have AQ on the above board and action, but MP1 check raises you on the flop, its still a fold. LIMPERS DO NOT LIKE THEIR HANDS! IF THAT CHANGES, GET THE **** OUT OF THE POT.


GANGUP EFFECT

Let's talk set mining for a bit. We all know the math, 5-10 rule and 1:8 blah blah blah. Well guess what? All that standard math is for HU pots and doesn't matter in multiway pots. We all know that if you can get a villain to put in 15-20% of their stack preflop when you're holding aces that they cannot profitably setmine, that you can safely stackoff postflop and STILL be +EV. Well, not so much if you're playing against a field and are not HU postflop.

You're OTB with AA. Time to make some money, amirite! Four limpers to you, std 2+2 raise of 4+1, you bust it to $2... everyone calls.

"Stupid idiots. All four of them just called without good odds to setmine, putting in too much of their stack to be profitable in the longrun. Gogogogogo!"

*buzzzz* Thank you for playing. Please head to the back of the line and practice your EV calculations.

Each one may have made a -EV call individually, but you're playing against the field. Peel back the curtain and all 4 have small pocket pairs, say 22, 44, 55, 77. There is now a huge chance that the field catches a set, something like 42% on the flop. You're now in the awkward position of having to cbet and give up on this hand, because putting in any more money than that makes you -EV. All it takes is one idiot with KTo to feel priced in preflop, spike his T on the flop and peel your cbet, then put you on AK and bet the river and BAM you fold the best hand. Yuck.

"But I did what I was supposed to do and raised! What do you want me to do, limp and setmine aces to avoid -EV situations?"

No. But this CoW is not called Raising Limpers, its called Isolating Limpers. Same example, AA OTB with 4 limpers. Make the bet $3.25. Now you get one optimistic caller who is bad at math... feel free to stack off happily. NH, GG.

"But what if they all fold? I make the minimum with my aces?"

Yes, but you make money. +EV. Playing against a field is not like playing against one villain. Each one can individually be -EV and you are STILL -EV also. Let me repeat that: each one can individually be -EV and you are STILL -EV also! Because you're not playing against a hand, you're playing against many hands. You're better off winning a small pot with your big hands than getting yourself into a pickle against a large field where you have high RIO. Reverse implied odds my friends... limpers are playing for Implied Odds, and when you have a good hand against limpers, that means you have the opposite, Reverse Implied Odds.

For advanced readers only:
Spoiler:
Note how the previous example plays essentially the same if you have Q5s as if you have AA. We'll get back to that later on. But first...


Another example:

Unknown villains, full stacks.

Pre Flop: ($0.35) Hero is BU with A J
1 fold, UTG+1 calls $0.25, 1 fold, MP1 calls $0.25, HJ calls $0.25, Hero raises to $1.25, UTG+1 calls $1.00, MP1 calls $1.00, HJ calls $1.00.

Flop: ($5.35) T A 9 (4 players)
UTG+1 checks, MP1 checks, HJ checks, Hero bets $4.00, UTG+1 calls $4.00, MP1 folds, HJ calls $4.00

Turn: ($17.35) T A 9 6: (3 players)
UTG+1 checks, MP1 checks, Hero ??????

Kicks a puppy? What now? OHAI you're in a world of hurt!

Let's peel back the curtain and see that UTG+1 had 99 for bottom set and HJ has QJ for the OESFD. Yeah, HJ could have just as easily had 87 and made his straight. UTG+1 got greedy and tried to trap more money in the pot with his set (yes, even with the FD out). And you... you want to puke. Bet/fold and protect against the draws? Check for pot control and call one on the river if the flush doesn't come in? Or just c/f from here out, and risk folding the best hand or allowing them to draw out? ****. Let's try that again!

Pre Flop: ($0.35) Hero is BU with A J
1 fold, UTG+1 calls $0.25, 1 fold, MP1 calls $0.25, HJ calls $0.25, Hero raises to $2.50, UTG+1 calls $2.25, MP1 folds, HJ folds.

Flop: ($5.85) T A 9 (4 players)
UTG+1 checks, Hero bets $4.00, UTG+1 raises $8.00, Hero???

Folds. Much better!! Hopefully next time he doesn't get so lucky and flop that set.

Most big hands play better against a smaller field, and big preflop raises will accomplish that. Don't get married to one preset "strategy" for preflop hand selection or bet sizing. Think about why you are raising each time, and size your bet to accomplish that.

FREE MONEY

Now that we've discussed some of the advantages of isolating limpers, let's start talking about how to use these advantages to make money. You know how you open your range in late position to steal the blinds? Yeah, if you don't know why you're doing that, go read Happy Pixel's treatise on the subject. I quote:

[QUOTE=HappyPixel
It's only 1.5BBs, why should I get involved?

Because 1.5BBs is a LOT OF ****ING MONEY!!![/quote]

The blinds are forced to put money into the pot with any hand. But there's another player that puts money into the pot with marginal holdings: the limper. One more time, everybody now! Limpers are bad at poker and are unsure about their hands. Every time a limper enters the pot in front of you I want you to hear this sound in your head: "CHA-CHING!" That's your EV cash register counting up the bad money in the pot sitting out there for the taking. Another example, again unknown villains and full stacks.

Pre Flop: ($0.35) Hero is HJ with two cards
4 folds, Hero ???

It gets folded around to you, what's your standard opening range here? I don't know, but let's make one up for the example. Let's say any two suited broadway, ATo+, KQ, and any pair. Fair enough? Time to tweek it.

Pre Flop: ($0.35) Hero is HJ with two cards
3 folds, MP1 calls $0.25, Hero ???

What's your opening range now?

"Well, I was against random hands before, this time villain has a hand he wants to play, so I'll tighten my range a little to preserve my equity edge and be +EV when entering the pot."

YOU! BACK OF THE LINE!

What have I been prattling on about all this time? Isolating limpers gives you a positional edge, it gives you a initiative edge, and it gets you involved in pots with bad players who don't like their hands. You don't need to protect your equity edge when you have all this other stuff working for you! Here, let's try that again:

Pre Flop: ($0.35) Hero is HJ with two cards
3 folds, MP1 calls $0.25 CHA-CHING!, Hero ???

"OK, I get it. He's probably got a small pair or something suited there and will need to hit the flop hard to continue. Well, there's still a lot of players left to act. What if I added any suited aces to my open range?"

Yes, good. Suited aces are ahead of a ton of his range (suited junk), and when he's got better (small pairs) he STILL needs to hit the flop to want to continue. Plus, suited aces can hit the flop many ways and play well postflop. A+. One more time:

Pre Flop: ($0.35) Hero is HJ with two cards
UTG calls $0.25 CHA-CHING!, UTG+1 calls $0.25 CHA-CHING!, 1 fold, MP1 calls $0.25 CHA-CHING!, Hero ???

Now what?

"That's a lot of money out there."

Indeed.

"But I don't want to play easily dominated hands, right?"

*cough*

"OK, OK. What if I opened... any 2 broadway, any ace, and any pair? Is that OK?"

You are such a LAG. Welcome to the wonderful world of exploiting weak players! Here's you diploma and a couplon for a free Happy Meal.

Pre Flop: ($0.35) Hero is HJ with KJ
UTG calls $0.25 CHA-CHING!, UTG+1 calls $0.25 CHA-CHING!, 1 fold, MP1 calls $0.25 CHA-CHING!, Hero raises $2.00, 8 folds.

Results: Hero wins pot $1.35, profits $1.10.

Nice hand.

"But they NEVER FOLD in the micros! I don't know how it is at your stakes, but they ALWAYS come along, and now I've got a crap hand in a big pot!"

Sometimes. Do I have to repeat the mantra again?

Pre Flop: ($0.35) Hero is HJ with KJ
UTG calls $0.25 CHA-CHING!, UTG+1 calls $0.25 CHA-CHING!, 1 fold, MP1 calls $0.25 CHA-CHING!, Hero raises $2.00, 6 folds, UTG+1 calls $1.75, MP1 calls $1.75.

Flop: ($6.55) T A 9 (4 players)
UTG+1 checks, MP1 checks, Hero bets $4, 2 folds.

See where I'm going with this?

"Um, they don't always miss."

You're right. About 25% of the time it will go like this:

Pre Flop: ($0.35) Hero is HJ with KJ
UTG calls $0.25 CHA-CHING!, UTG+1 calls $0.25 CHA-CHING!, 1 fold, MP1 calls $0.25 CHA-CHING!, Hero raises $2.00, 6 folds, UTG+1 calls $1.75, MP1 calls $1.75.

Flop: ($6.55) T A 9 (3 players)

UTG+1 checks, MP1 checks, Hero bets $4, UTG+1 raises to $11, 1 fold, Hero???

Any doubt about where you're at in this hand? So 75% of the time you win $4.65, and 25% you'll lose $6. I'll let you work out the EV calculation.

SUMMARY

Abuse the limpers at every opportunity. That is all.

I was originally going to include a quiz and a video with my CoW, but I ran out of time. Maybe I'll add them later in the week.

My apologies for all the set-mining nits who are going to start wondering why no one ever pays them off anymore and where their winrate disappeared to.

CHA-CHING!

To this excellent article I would only add: You do have to be mindful of who you're isolating. A lot of limpers are loose-passives who are going to call you down with third pair and ace high, so you're just going to valuetown yourself iso-raising them and then firing two or three barrels, only to discover they called down with 66 on a 4KT82 board anyway to beat your ace-jack. Or they call down with ace-nine to beat your queen-jack.

I'm not saying don't iso-raise these guys, but it's often better against them when your hand is two high cards to just peel cards, rather than try to c-bet them off their hand, when you miss. Some of them can be moved off with two barrels (these guys are ultra profitable), others can't. Know your villain.

Awesome follow-up post bro. I know the focus is on the "iso, then cbet line", but man that flop is so massively donk-friendly that I'm not sure we get the 40% fold that we need to make the cbet profitable. I suppose that's another topic...thinking more, since we have 8 outs (6 if he has a FD), it might not be so bad. Do you cbet boards like this against stations, or are we just opting to limp along for the increased IO against this type of player?

I have trained myself to look 1st at their fold to flop c-bet stat when deciding to isolate, then to pay a bit of attention to their vpip/pfr.

Hey RE,

There's a lot I didn't cover. Like what if you're trying to isolate someone by raising a bunch of EP limpers, and then someone calls in position on the button... what then? You're going to have to play some poker. Limpers juice the pot with bad money and isolating them helps your big hands play better, that much is true. You'll always have to adjust to individual players and to table conditions, but "iso then cbet" is tremendously effective against the weak limpers in the micros.

At least in my experience.

I don't advocate limping non premium hands at the micros. I said that at 2NL and 5NL specifically that limping PP's can be +EV, which isn't true at any other level. The reasons for this are because people don't punish the limpers at 2NL or 5NL pretty much ever in my experience. The reason I specifically mention PP's is because most of the time you need to take them down with a continuation bet on the flop, but at 2NL and 5NL the FE for contuation bets is very, very small, which lessons the edge you get from having initiative.

Not only that, but isolating limpers isn't something most 2NL or 5NL players are going to be worrying about.

LIMIT SPECIFIC ADVICE: JUST HOW ******ED ARE MY OPPONENTS?
2NL & 5NL - One thing is very profitable at these limits that isn’t profitable anywhere else. Limping. Part of the reason is because you are deep stacked with 200BB’s. The other part of the reason is that people aren’t that aggressive pre flop and most of the time people won’t be raising over top of a few limpers. You can limp any pocket pair from almost any position and it will be a +EV play. Always raise your unopened strong holdings as normal, but be a bit more liberal with your limps. Speculative hands are great when you’re playing 200BB’s deep and your opponents aren’t aggressive. At this limit weak tight is super profitable and you can play like a nit and still get paid off by any fish with a pair.
(emphasis mine)

First, his advice is for 2nl and 5nl only, because they are deepstacked providing a lot of IO. Note that I covered IO as the main reason to limp.

Second, read the portion I highlighted again. Limping is profitable as long as people don't behave the way I outline in this CoW. Basically, Sir Cuddles is telling you how to take advantage of people who call too much postflop, and I'm telling you how to take advantage of people who try to take advantage of people who call to much postflop.

In short, isolating limpers destroys their EV, their profit. If people were to isolate, limping wouldn't be profitable.

So basically, Sir Cuddles and I are in agreement.
