Poker is a game that is based around gathering information, processing that information, and using the analysis to create optimal strategies. This COTW will be about information and the processing of that information. Often times we either ignore, or totally miss, great pieces of information that can help us shape future lines and strategies.

Let's first start with information gathering. We do this in many ways. From figuring out what action our opponent made, to using HUD stats, to using HUD stat correlations, to inferring how a particular table is playing. When applicable, we also take this a level further and figure out how our opponent views us, what we represent, what range he probably has, etc. We should be gathering information every single hand, both about the hand being played and about how we might shape future actions. Let's start with a basic hand:


Poker Stars $0.50/$1 No Limit Hold'em - 6 players

CO: $104.45
BTN: $100.00
Hero (SB): $125.80
BB: $38.85
UTG: $100.00
MP: $60.25

Pre Flop: ($1.50) Hero is SB with :X: :X:
3 folds, BTN raises to $3, Hero raises to $10, 1 fold, BTN calls $7

Flop: ($21.00) 6 6 7 (2 players)
Hero bets $11, BTN calls $11

Turn: ($43.00) K (2 players)
Hero checks, BTN checks

River: ($43.00) 8 (2 players)
Hero bets $22, BTN calls $22

Final Pot: $87.00
BTN shows T T

This hand probably looks like nothing special. But if we think about certain things, we can get various nuggets of information. Here is a rough list of things to consider:

Let's take another hand:

Full Tilt Poker $0.25/$0.50 No Limit Hold'em - 9 players

Hero (UTG+2): $55.60
MP1: $29.00
MP2: $50.00
CO: $30.25
BTN: $84.70
SB: $60.15
BB: $76.25
UTG: $50.35
UTG+1: $42.65

Pre Flop: ($0.75) Hero is UTG+2 with :X: :X:
2 folds, Hero raises to $1.50, 3 folds, BTN calls $1.50, 2 folds

Flop: ($3.75) 6 Q 8 (2 players)
Hero bets $2.60, BTN calls $2.60

Turn: ($8.95) T (2 players)
Hero bets $6.15, BTN calls $6.15

River: ($21.25) Q (2 players)
Hero bets $45.35 all in, BTN requests TIME, BTN calls $45.35

Final Pot: $111.95
BTN shows Q K

Let's see what information we can take from this hand:

None of this is complicated at all. We are both looking at the same hand, and the possible assumptions are pretty logical. However, the difference between bad and good, and good and great, players is what is done with that information. Bad player ignore the information they were just given. Good players remember those notes for future plays. And great players create a baseline for that opponent as to more perfectly exploit that person in the future.

The great thing about humans is that they are all creatures of habit. “If A works, keep doing A.” People really only deviate from A when A fails (either many times, thus negating their positive pattern, or once, and maybe making results-oriented changes). So in the second hand, I might not expect player A to call my shove in the future if I turned over 88. But if I had a total bluff, I expect player A to call me in that spot the next time. We are all human, we are all dumb...exploit that.

Analyzing information is the next part of the puzzle. Gathering information isn't too tough, especially with HUDs and note taking programs. But analyzing that information is where many players tend to fall down. They either don't know how, or they don't do it logically enough. Everything from analyzing what a 7% cold call stat means, to analyzing a villain's bet size on the turn is important. Let's analyze some basic things.

MP1: $69.00
MP2: $108.50
Hero (CO): $100.00
BTN: $104.80
SB: $152.25
BB: $37.50
UTG: $102.45
UTG+1: $43.75
UTG+2: $98.00

Pre Flop: ($1.50) Hero is CO with :X: :X:
5 folds, Hero raises to $3, 1 fold, SB calls $2.50, 1 fold

Flop: ($7.00) J 8 3 (2 players)
SB checks, Hero bets $4, SB calls $4

Turn: ($15.00) 5 (2 players)
SB checks, Hero checks

River: ($15.00) T (2 players)
SB checks, Hero ???

So we can gather some basic information. Villain called a steal from OOP (instead of restealing). We can build a range (probably not including super strong hands, but his resteal/3bet stats could help confirm that). He check/called the flop (instead of raising). He has kept a very passive tone this entire hand (called or checked on every action). The interested spot is his check on the river. Is he the kind of guy to check a Jx here?

In most instances, probably not. He has no reason to think that we would bluff (if we didn't bluff the turn, why would we bluff the river?). So any Jx he has would have to bet himself, logically, so we can probably discount combos of Jx from his range. Because of that, we can discount combos of sets, Q9, etc. So his check on the river is probably some sort of 8x, 99, QT, KhXh type hand. But does he call steals OOP with QT? What about 98? Would he fold if we bet? Are we bluffing? What is going on here?!?!

While on the river we could simply ask ourselves “what is our hand strength and what does a bet accomplish?”...but in order to grow and find creative ways to inject value (by bluffing or VBing), we need to dig deeper. We need to analyze information. We need to analyze what his actions tell us about his range. We need to analyze, if applicable, what our actions might tell him. Overall, we need to never stop analyzing and using the analysis to create lines (like overbetting the river to $27 because he wouldn't call with 8x =) ).

The great thing about all of this is that every bit of information is useful. Did our opponent call our 3bet with AA? (sweet, his 4bet range might be tainted). Did our opponent call a 1/2PSB river bet? (did he do it with a really ****** pair? Might he have a calling station tendency?). Did our opponent take a long time to do X action? (how does that compare to his previous actions and timings? Is he giving away timing tells?) Is my opponent playing more aggressively against me? (would he notice if I tightened up entirely? What if I only tightened up a little?) Did my opponent put in ½ of his stack and then fold getting 3:1 on the river? (what we would do that with? Does he maybe have an inability to plan through hands?) Did my opponent call my steal OOP with XX? (if so, I have an idea on his CCvsteal range. Do other hands group with that to give me an even better idea of his future range?) Did he show me he probably understands SDV, polarization, aggressive play with XX hand, etc? How can I play more perfectly against him in the future?

Information is everywhere (in winning hands, losing hands, and hands we didn't paly)...but it is up to you to polish it and turn it into useful strategies. If you see a hand get to showdown, take a note that he does X with Y. Pot size, bet sizes, hand strengths, his PF actions/range, his reaction to Y play, etc. are all notable. Don't be lazy with this, and you should be able more correctly adjust to regs, fish, and anyone you may encounter at the tables.

Let's start a conversation...

first.. good article.

.

Terrible article, no one read it, it's totally wrong

<_< >_> <_>

j/k but please no one read it.

Great post . Just wondering though split , if this is the kind of stuff we need to know to play micro's , then what do small stakes / middle stake guys think about ?

what is SDV???

this isn't really beginner stuff. This is stuff you start improving on as you run out of fundamental things to improve upon. imo

showdown value

and thanks for the kind words everyone =)

To build on the idea of accumulating information - the next step is to take that info and build better ranges for ourselves. This might involve shifting 3-bet ranges from polarized to de-polarized, greatly expanding/contracting opening/flatting/3-betting/4-betting/shoving ranges, etc.

Sure, stats/HUDs are useful, but there is always the possibility that a player's range of hands for any action is very different in a specific spot than it is overall.

Also, Diamonds And Coal - Incubus http://www.youtube.com/watch?v=3m3kvTE7XKI

Seriously split top draw stuff here will re-read many times.

are showdown value and value betting related??...is SDV something like in hand 1 villian checked turn with TT bcoz he thought they were good enough to win at showdown but he would get called/raised only with better hands if he bet??

is there a detailed post somewhere on SDV??

Hey Split,

Awesome stuff, I'll definitely have to be more studious with note taking after reading all of this and praying my opponents won't do the same!

My question is when and to what extent do you synthesize this information? I'd imagine writing as many notes as you did on the sample hands can be kind of tricky when you're multitabling. Do you prefer to note-take mid-session and use those notes for future hands in that session, or do you prefer to finish up, boot up HEM and analyze every play by your opponents for flaws?

And also, it would seem there's a strong possibility about information overload. I'm not suggesting there's too much of a good thing against extremely tough players, but I would guess you get diminishing returns when you note that a fishy TAG will 3bet suited connectors between 56-98 but flat calls all the rest, as this situation comes up rarely and you'd be better focused on other things. Thoughts on this?

thank you. it's multi-layered...so hopefully each read yields something new

i talked about SDV in my COTW on planning...but I don't believe anyone has done a specific COTW on it.

id say you are on the right track. for me personally, i keep a ton of mental notes. I can often times see a reg a few days later and still be able to recall certain hands/reads that i have on him. that being said, most all of my notes are villain v me notes...because I can get usually generate more global reads from the HUD

yes, you can get info overload...but your main goal is to build a good baseline for your opponent so you can figure out his "waves' before he even does =)

Split - seriously please lock and delete this thread. The information you are giving away here is too valuable. jk - I mean I love this cotw because it tells us what we need to do, but <0.1% of players will be bothered doing it and incorporating it into their game. But seriously, arguably the best post cotw ever imo.

1 complaint though - I thought you were gonna give away an actual get rich quick scheme. You mean I have to work to get rich????

Great post split.

Move along, people. Nothing to see here.

But seriously, I know this is probably the most deficient part of my game, and that's really saying something because I suck pretty bad.

I also think this will have quite a direct impact on tilt control by being more prepared for the line a villain will take, rather than just getting AI by showdown and screaming WTF is that ****ing donkey doing calling my pre-flop 3b OOP and flopping the world every damn time mother****ing ****er **** **** ffffffffffuuuuuuuuuuuuuuu.
