View Full Version : Theoretical Musings: Playing Draws on the Turn Heads-Up

All right,

So I love poker theory (and most forms of things that have theoretical underpinnings, except literary theory, which I despise), and I figured I'd make a "theory" type post in the Small Stakes board because, well, I like this board and the "Poker Theory" board doesn't get as much action, and because I think my thoughts have a particular bearing upon playing small and middle limit hold'em.

[Disclaimer: I make no claim that any of this is new or ground-breaking or that it isn't repeated almost word for word in some book which I may have read or have yet to read.]

I was reading and replying to a post by Dagger78 earlier today about playing KQ in a heads-up pot, where the hero three-bet the flop with overcards and a gutshot and (in my opinion correctly) took a free card on the turn. It got me thinking about playing what I would consider medium to strong draws (6 clean outs or better) on the turn, in position, in heads-up pots. In many situations, particularly if you are the aggressor and have bet/raised the turn, it is correct to check in position to take the free card, get to see a possible hand-making river card for free, and avoid getting raised and paying excessively for your draw. In general, it is almost certainly correct to take the free card whenever the following are true:

1. Villain is very likely to have a better hand and is very unlikely to fold. (Fold equity is maybe the single most important consideration; I remember hearing a comment from a respected Mid-High poster who commented that he rarely uses the free card play, because after having raised the flop with a draw he generally preferred to encourage his opponent to fold on the turn.)

2. Villain is particularly likely to check-raise and force you to pay for your draw.

3. You have only a reasonble number of outs (a standard straight, flush, or overcard+gutshot type of draw, where you have 10 outs or fewer).

I began to consider, though, that there is another very important thing to consider in thinking about whether it is correct to bet the turn, in addition to these factors (fold equity, likelihood of getting raised, and strength of draw).

That factor is your hand's showdown value. (Obviously, many of you might be saying).

But I began to consider a question I realize I haven't considered much before: How does your hand's showdown value on the river affect the decision to bet or check the turn after you've raised the flop with a draw?

After sitting through two boring sections today, I came up with this thought. PLEASE let me know if this exact situation is discussed in a major poker book so I can feel like a loser for posting this.

If you have raised the flop in a heads-up pot with a draw and you do not complete your draw on the turn, it is correct to follow through with a bet if the following are true:

-Villain is unlikely to check-raise the turn.
-Your hand has enough showdown value that, if you checked behind the turn, you would plan to call a river bet unimproved.
-Villain is likely to bet the river with many hands if you check behind the turn.

Here's an example:

You open-raise in late position with A /images/graemlins/club.gif K /images/graemlins/heart.gif. You are called only by the BB, who is too loose and generally passive, though occassionally erratic (so, a standard small stakes player).

Flop: (4+ SB) Q /images/graemlins/club.gif T /images/graemlins/diamond.gif 6 /images/graemlins/club.gif

BB bets, you raise, BB calls.

Turn (4 BB): 5 /images/graemlins/heart.gif

BB checks... you should bet.

The basic idea, which I'll expand on later after some discussion (hopefully there will be some), is that if you are unlikely to be raised, and you are planning on putting one big bet in either the turn or the river because you have enough showdown value to do so, it is much better to put that bet in on the turn rather than the river, when your equity is higher.

Pretty simple stuff, I guess, but I really enjoyed thinking this problem through today and I thought I'd share it with you.

Interesting. But what do we do once the river hits and we miss our draw? Assuming we're in position, do we fire one more bullet? After all, our hand does have showdown value. Occasionally we'll get called down with something such as AJ (in the example you used) and other times we might encourage a low to mid pp to fold, or perhaps third button. I like the way you're connecting these thoughts together to try and make a theorem, but I'm curious how betting this turn, instead of taking the free card, affects the rate at which we bluff the river (especially when our bluff might occasionally be a value bet.)

I see you working.

What I'm thinking is that a 'typical' opponent who bets that flop (in your example hand) is going to have at least a pair and will showdown a ton of the time unless the board gets really ugly for him. He's very unlikely to fold any better hand.

In other words, I think it might be easy for us to overestimate the amount of times we win unimproved against this player, and also to overestimate the amount of times a 'typical' player bluffs on the river (after we check the turn). (Against a lot of players you can safely fold to his river bet even after checking the turn through.)

i agree 100%. i made a post about this in HUSH yesterday.


edit: you should ONLY bet this (or raise if he bets) if you are DEFINITELY going to showdown. don't raise with an unshowdownable hand in this spot unless you have 23 outs or better.

If we're thinking about the same hand (57s) I'm pretty sure your thinking was wrong in that case and W. Deranged's thoughts don't apply there. /images/graemlins/shocked.gif

*shrug* we can disagree. i think i was making the same point as deranged was -- that we have a showdownable hand and putting bets in on the turn is better.

looking back at that hand i think capping is better than call/calling in that hand.

Yeah I understood what you were saying yesterday, I just think it's wrong (because of the possibility of having to pay a 5th bet on the river). We can bump that hand if you'd like.

that hand is a special case. it seems like we should be behind but FV felt at the time that with all the draws on the board that he was ahead on the turn, and that's why he capped it. my original reasoning (although i dont think we put in a 5th bet in often) was off because i think he sucks out on us more than we suck out on him.

I've gotta go look at this hand...

If you have raised the flop in a heads-up pot with a draw and you do not complete your draw on the turn, it is correct to follow through with a bet if the following are true:

-Villain is unlikely to check-raise the turn.
-Your hand has enough showdown value that, if you checked behind the turn, you would plan to call a river bet unimproved.
-Villain is likely to bet the river with many hands if you check behind the turn.

-Villain needs to fold often enough for this to show profit; that is, an appropriate amount of FE should be inherent in the situation for this to be appropriate.

Obviously it's nice for villain to fold some of the time, but my major point here is that even if villain is not going to fold all that often, if you think your hand has any showdown value at all (namely, you think there is some significant percentage of the time that you are ahead) then you should bet. This is true even if the majority of the time you are not ahead AND villain is almost never folding a better hand.

The major idea is this:

If we bet now, and villain is unlikely to raise us or donk-bet the river, we get to check behind the river now. At this point, with all of our draws still live, we have considerably greater equity than we would on the river if we miss. Hence, our "refund" on our turn bet is substantial.

If, on the other hand, we check, villain will bet into us, and we'll have to call because we have showdown value and need to call because we believe villain is bluffing with a missed draw often enough for us to profitably do so. (I think both Sklansky and Ciaffone/Brier say that you need to be very willing to call the river with a big A unimproved if you check it behind on the turn against most non-rockish opponents). The problem is, our equity is much lower than it would be on the turn, and so the river call is less profitable than the turn bet would have been.

My point is that this is true even if we don't think that villain will fold often.

The idea is basically that whenever we have considerable equity that comes from both a potential draw and possible showdown value, it is much preferable to bet the turn and attempt to showdown for free, than to check the turn and pay for the showdown. Two important thoughts:

-Against hands that we are beating, our turn bet is for value; though we'll often be able to snap off a bluff bet from these hands on the river, such hands may not always bet the river and by not betting the turn we've foregone a value bet.

-Better hands are very rarely checking both streets, and so we need to choose where to put the bet in.

Therefore, since betting the turn or checking the turn and calling the river are essentially analogous against better hands, we should basically determine our turn play based on how the plays compare against worse hands. Against worse hands, betting the turn is clearly correct, and, even if the percentage of the time we're against worse hands is not huge, and villain is not folding often, this difference in play versus worse hands tilts the play in favor of betting the turn.
