At this point, you are calling 4000 to get a chance at winning 20,900. You need only 16% equity to make that call. Giving player A a range of A8+, KJ+, and 55+, and given the button a tighter range of AJ+, KQ, and 77+, you would have equity of about 20%. More importantly, you left yourself 2.5 BB and tons of action behind you.

You were pretty much done, but the correct move would have been to call with 5 to 1 pot odds.

I'm new at this and am from the Harrington school where we deal with odds. I'm not familiar with the "equity" approach/system. Can you translate your answer? I actually would place Player A in a much tighter range, but I guess our main difference is that I was pretty sure I was beaten in this hand, and you seem to be saying that I had a 20 percent chance to win against both players? Can you explain how you arrived at that figure?

Odds are basically a ratio of one outcome against another. If you have a sizx sided dice, your odds of rolling a 6 are 5 to 1. For every time you roll a six, on average, you roll 5 non-sixes. For poker, this is useful, as it gives you the necessary ratio of what you will win versus what you must wager. If I am on the turn, and I have a nut flush draw, and my opponent has moved all in, I just need to compare the ratio of what is in the pot to what it will take to call to the ratio of cards that do not make my hand versus the cards that will make my hand. For example, if he bet \$500 into a pot of \$500, you have to wager \$\$500 to win \$1000. Your pot odds are two to one. If you are on a flush draw on a non-aired board, and you know he has at least a pair, you have 9 cards that will make your hand 37 cards that will miss. Your odds are 37 to 9 against. Since the ratio of 37 to 9 is higher than 2 to 1, you should not call. Equity is a related concept. It is the percentage of time that your hand wins. This is calculated as total favorable outcome divided by total outcome. Odds are the ratio of unfavorable outcomes to favorable, equity is favorable outcomes/(unfavorable outcomes+favorable outcome). In the example above, you would have 19.5% equity. Equity has the advantage, though, of being an easier number to work with when calculating against a range. Let's say you are facing a preflop all-in decision where you raised, and villain three bet shoves. You have pocket queens. You estimate his range to be AK, JJ+. Based on this, you can calculate the equity for QQ versus AK, QQ versus AA or KK, and QQ vs JJ, then use a weighted average to calculate your equity against his range. That is very difficult to express with odds. Equity and odds can be used when comparing simple action with only two end states. For example, when considering whether or not to call all-in on the turn. They are less suited for guiding action where there may be multiple outcomes (if I bet, will he call, raise, or fold, and what is the equity and pot size of each outcome). This is where EV, or Expected Value, comes in. EV is basically the weighted average of every possible outcome (the value of the outcome multiplied by the likelihood of the outcome). I won't go into it too much in this post, but it is really the number you should use to guide your action.

 Following Harrington, my M is about 3+, so I'm just waiting for it to be folded to me before shoving with any two cards.
If you are purely a leisure player, ignore my advice.

If you want to improve as a tourney player, reconstruct this hand, with the payout structure, blinds and stack sizes behind, with an ICM calculator in order to a. evaluate Harrington's strategy of shoving in this spot with any two and b. developing an interest in ICM.

as played I think it is a nailed on call and I don't "vigeroush" has got anything to do with it. Spewingismymove basically nails it, esp on stack size remaining (which is why Harrington would have called as well).

This is not true. I can see the other players arguing that OP should call with any two cards, so they don't necessarily have to see what he folded to start a debate.

If I'm shoving the only thing I say is all in, if I'm raising the first thing I say is raise, etc etc

Hi, All, thanks for the very informative replies. I'll try to buckle down and learn about equities and EV as suggested.

As it turns out, I did NOT tell them what my hand was. I try to never show unless I have to.

Fatboy, I don't know what an ICM calculator is. Can you direct me to a starting point? Also, if I understand him correctly, Harrington's "vigorish" means that players behind you are more likely to fold to your open-raise all-in. In my situation, my last 4000 in chips and any two cards would have some "vigorish" when I open-shove, although, as Harrington himself points out, only a minimal amount, since 4000 in chips would be only a little more than a min-raise.

I'm still in the dark as to how SpewingIsMyMove arrived at the 20 percent win probability in his reply. Can someone enlighten?

It seems to me now that, if SpewingIsMyMove's 20 percent figure is correct, this really becomes a debate between going with your read or going with the math. My read was that I was beaten and my tournament life would've ended had I called, while folding gave me a small but finite chance at resurrection.

Thanks again, guys. Learning a lot here.

 04-07-2018, 06:02 PM #11 Kelvis Carpal \'Tunnel   Join Date: Dec 2013 Posts: 6,194 Re: String bet 20% is just the equity you might have here against some shoving ranges. In other words you will suck out about 1 out of 5 times and win the pot. How can you tell your tournament life would have ended? So I actually looked at the math and J7o does really really weally badly against overpairs. But even then, if they have overcards or TT then you're doing ok and they don't always have a pair so folding would seem ridiculous. Last edited by Kelvis; 04-07-2018 at 06:13 PM.

I haven't read Harrington in awhile, I do not recall his concept of vigorish. It sounds like you are describing fold equity, which is the gain equity from an action due to the liklihood of opponents folding. In this situation, any players that would over shove your first raise would not have folded to a shove. When they shoved on you, they were certain that you would have to call, so they were happy to play you for stacks.

Regarding how I came up with 20%, I simply used an equity calculator (in this case Equilab) to calculate your hand versus likely ranges for each villain. There is some estimation in trying to determine their ranges, but we can make a fair approximation.

Again, I can't speak to Harrington, but I can tell you this. When your stack is between 5 and 10 big blinds, you really want to start shoving into unraised pots very wide. At that range, you still have fold equity, as your stack is big enough to hurt players calling you wide, but your stack is small enough that it isn't worth making a standard 2.5 or 3 bb raise. My ranges vary a bit, based on position and table dynamic, but if I am around 10 bb, I am shoving any unopened pot with any ace, a lot of broadway combos, a lot of mid to high suited connectors.

Regarding ICM, ICM stands for Independant Chip Model. It is somewhat of an advanced cooncept if you are still learning about equity and EV, but it is basically a way of looking at the payout structure and player's stacks to determine the approximate dollar value of your stack. In tournament play, this is very important. For example, let's say you are on the bubble of a tournament, you have AK on the button. Two smaller stacks go all-in in front of you, then a stack that has you covered goes all in. In many situations, you would be justified in calling. But using ICM, you can determine that calling this bet actually loses you money, so it is an easy fold.

Let's make sure you understand equity against ranges and EV first before we start talking ICM.

Everything has to be looked at from the standpoint of what you risk versus what you gain. You were almost certainly behind at that point, likely by a lot. But you had only to risk 4000 more chips for a chance to win nearly 25K. You don't need a lot of equity to justify that call.

If you do not make that call, you are UTG+2 with 2.5 bb. This means you have almost no fold equity (your bet is not going to scare away any viable hands), and you have only 3 hands to catch a good hand. And any hand you catch is going to have to stand up to between 7 to 9 people acting behind.

Realistically, you were pretty much a deadman walking anyways. But calling for the 4K was your best option. Everyone one of us here has seen (pretty frequently it seems) two crap casrds take out an over pair. And if you were dealing with two big aces (e.g. AK and AQ), you are actually not in horrible shape.

The final pot is 20,900 + 4,000 = 24,900 and your 4,000 call is 16% of that total.

What would Dan Harrington say to do in that spot?
