In the hand where the weaker player limps utg, you decide to raise Q9o and mentioned the reason why you wanted to raise. I've always thought a raise was standard, but do you think limping your whole range will play better, since you'll have some strong stuff to continue with by calling or limp reraising, and you'll be able to complete a bunch more hands getting great pot odds? I guess it's pretty similar to sb vs bb play opened?

Cool hand with the 98s. 


With the ch/r with 76hh as pfr CO v BTN on K52hh, you mention you expect better FDs to call and then jam turns a bit. On a 6 or 7 turn would you just continue by betting, to b/c. Ch/c seems meh..

What do you think of ch/r flop with ur some Axhh hands that will presumably be able to b/c a lot of turns and possibly get it in good?  

For feedback- I really enjoy these vids where you go with your reads and punish ppl. It could be at .01./.02 or 100/200 and the content is always A+. It seems like zoom works really well, too.

Thanks, mplecki.

Q9o- I prefer raising to limping, as even if the BB checks (which is desirable with much of my range), I've still missed out on bloating a HU pot against the (likely) weaker player.  I am not so worried about range protection in a spot like this.  If the BB starts punishing me for my iso, I'll have to tighten up in this spot, and 4bet wider against him.

76hh- I'd probably just bet on a 7 or 6 for the reason you mentioned... meh :)

With Axhh, x/r is okay with this hand, but I think hoping to induce a turn shove (and get it in good) is ambitious, and should only be a very small consideration.

I prefer betting with the nfd, occasionally even x/c on the flop or turn to allow him to bet hands with very poor equity and then try to rep my flush (or hit a lower one himself of course).

Kh 5h 2s : why would button ever bet flop when you check to him if you have much more value combos than he does ? Are you just exploiting him thinking he'll be unbalanced towards bluff when checked to ?

Phil Galfond 11 years, 9 months ago

It's a question of what he makes of my checking range.

I suspect if we looked at two preflop ranges for us, and looked at how things "should" play out, we'd find that he shouldn't be stabbing here often.

In practice, I've found people do stab, and I've also found that they are right to do so (against most checking ranges).

rjlynch 11 years, 9 months ago

with Td8d on the river at ~17:45, what are your thoughts on over betting here?

Phil Galfond 11 years, 9 months ago

I don't think this is the best spot to overbet.  Had the flush hit on the turn, rather than the river, I'd love an overbet with the top and bottom of my range.  I think it's clearly best (until he gets too tricky).

As played, there are plenty of Qxdd and Axdd hands that would check back this turn, so I would rather pick a spot where my opponent's range is more capped to start attacking with overbets.

min15 44 hand on KK4 9 6

I find very intresting the river bet-sizing. I heard a discussion a month before between GameTheory and another active member of RunItOnce where they arrived a conclussion. Something like: "When our range does not have enough bluffs, so the bluffcatchers of the villain hasn´t got equity enough to find a call, i just could overbet 100% of our range". Because any action that our villain takes different to fold, will always be better for us if we are overbetting, than betting 1/2 pot. He can´t call anyway to any sizing (1/2 pot or 2x ).

Do you think this could apply to this spot ? 

Am i right with my interpretetion of that ?

Andrew Sweeney 11 years, 9 months ago

Would love to read that thread if you could remember what it was called. It seams logical to me, strictly from a GT standpoint that if our betting range is comprised of 25% bluffs and we assume that our value betting never never get called by better(or raised) with .5P for sizing, a call will yield a payoff of 0 and and a fold will yield a payoff of 0 for villain. If we bet 2xP OTR a fold would yield a payoff of 0 while a call would yield -.75P for villain. So if we bet 2xP OTR it gives the villain the opportunity to make a bigger mistake. However if can ever call the 2xP bet that means he is not playing a best response to our strategy and we could be taking an exploitative approach. In a GTO equilibrium villain should be calling the .5P bet 2/3rds of the time, if he does not we can deviate to an exploitative strategy. I have always been unsure if a larger sizing (with a calling frequency of 0 for villain) would constitutes a GTO equilibria, as all strategy's with larger sizing mean heros payoffs: EV(VB)=P and a EV(bluff)=0. The downside to using larger sizing is it becomes increasingly costly when we cannot relax the assumption 'that our value betting never never get called by better(or raised)' its obviously rear when we can make such an assumpation.

Phil Galfond 11 years, 9 months ago

The main difference I see between the hand example in the thread (linked below by juan) is that there is a much greater chance in my 44 hand that we run into a monster.

Overbetting against a capped range is almost always going to be the best strategy, if that range is truly capped.  As we get further and further from 100% confidence in their capped-ness, the overbet becomes less and less attractive.

In my 44 hand, overbetting may be a decent option, mostly because I think it works better as a sizing if I want to turn weak made hands into bluffs (ace high, 54ss).

Juan Copani 11 years, 9 months ago

@Andrew Sweeny This is the thread. http://www.runitonce.com/nlhe/fire-river-after-float-200nl/

I also was thinking about last hand that Phil played with 75ss. What could be the best strategy in the opponent shoes once Phil checks the turn ? Like Phil said, he has to be very carefull to not be very bluffy with so many gutshots. 

I would be very intresting to see what´s Phil doing if villain 2x pot the river. Seems like a good spot to create an overbet strategy with our 6x/gutshots. Problem with this board, at difference to the thread´s board, is that villain range is not capped. And Phil could perfectly check/shove river with hands like J6/65/JJ. Which i also think we should do almost always.

@Phil,

The 76hh hand, why do you expect villains to stab much when checked to? Given as you mentioned you have many more value combos than villain, I dont think villains will stab this flop type much. Additionally he will expect you to cbet your air a lot so he will bet even less often. Your hand will be disguised but will still look like a non c/f range. Lots of QQ, JJ, etc. I like the concept of c/r here but I dont think villains will stab air and weak hands often enough to get many c/r's in. 

You stated that his betting range would be FDs, KX, and mid pairs. I think the mid pairs check a lot. Are you targeting hands like KQ, KJ that would never fold to bet bet bet, and now trying to get folds from those? If KQ, KJ, aren't folding then we are just inflating pot with a either dominated FD or a naked FD vs TP. Seems like a poor position to be in. 

That said, I guess we don't mind if it goes check check because we can delay cbet to fold out his air and medium PPs if our check range looks like marginal SD and slowplays.



Zachary Freeman 11 years, 9 months ago

@Phil,

On the AA9r flop you state that you think the best way to combat villain bluff raising you here when you hold a bluff is to 3bet, which in turn means we must occasionally deviate from the optimal vacuum play of just calling with hands like A7.

What are your thoughts on the following? We float with our bluffs, hands like KJ, QJ, Q8s, etc. to better rep SD like 9x and Ax type hands. If he gives up on turn and it goes check check, we can just SD with our K-high+ and pairs 9x and below given he is polarized. But with our floats weaker than K-high or if we start seeing he is raising merged than we can overbet or just bet large on river given he has capped his range with a turn check. 

If he is the type to fire the 2nd barell we can float again and also we can choose to cr rivers on K, Q, J with all non Ax hands.  If he is bluffing we just fold out his bluffs, but if he has Ax, we can get him to fold some as well given we dont have air after b/c c/c and we have so many more combos of AK, AQ, AJ than he does.

This strategy allows us to keep the b/c vacuum line with A7 as the range play as well. And I think will more credibly rep value hands when we float with our bluffs. It also protects our 9x, JJ type hands as well becuase we arent having to raise our Ax hands for balance.




Phil Galfond 11 years, 9 months ago

Hey Zach,

76hh-

My assumption was that most players will stab here with a very wide, merged range.  This is how people have played the few times I've played NL lately.  I'll admit, I'm out of touch with the games, so if people aren't stabbing here, my play loses a lot of merit.

A99r flop-

Floating here makes it very cheap for him to bluff while still realizing equity against our non Ax hands.  The problem I find is that it's very hard to profitably float the turn OOP, and we are too likely to face a turn bet to just float flop planning to give up on the turn.

Double floating OOP, planning to x/r some rivers doesn't tend to work well, as he'll bet river polarized and then check back marginal showdown value (that he already had, or picks up).  We end up essentially trying to bluffcatch on the river, but paying much more for it.

I agree that your suggestion allows us to play A7 and JJ better, but I think we lose a significant amount of EV with our bluffs... much more than we gain with our A7-JJ hands.

Zachary Freeman 11 years, 9 months ago

Good response. I do see the problem with floating mostly arises when villain fires the 2nd barell and gives up river. We don't get to lead river given he still is uncapped and has impetus and we don't get to c/r rebluff if he checks river. It works much better if villain makes a flop bluff raise but checks air and marginals on turn. 

Another benefit to your line is although Ax in a vacuum prob does better with a call, by 3betting we can rep a bluff and get floated.

76hh what do you think about having a 1.5x-2x flop cb overbet in this case then? Makes him define his range a lot this way
Andrew Sweeney 11 years, 9 months ago

With the 76hh hand I like the CR. My guess would be he is stabbing around 60-70%. I also think there are some bonuses relative to double barreling. 1) It defines villains range towards something that is quite likely to be CAPed, this gives us the opportunity to put in an over-bet OTT and we can follow threw OTR some% of the time. 2) IMO when we CR and barrel villain is more likely to raise or fold his FDs relative to calling with a higher % of FDs to a double barrel CB, im curious if others think that is true.
However In relative terms I don't think our value CR range is running into as fewer value hands then advertised. He has 6 combos of 22 and 55, we have combos 33 (AA,AK,K5s,22,55) and we look it as a ratio in absolute terms we have 6:33. If we are opening CO 28% and villain is flatting 14% the relative ratio is 6:16.5.

Brian Hastings 11 years, 7 months ago

On AJ hand on Jd7dTd brick turn board around 50 min, you say that you're afraid of betting turn because you are bet folding to a raise.  Why bet fold?  I think most players, especially someone half stacking and unlikely to be a good reg, are going to be unbalanced and have very few hands that beat you by that point, so even if you're still only 65-70% vs his semibluffs I feel like I'd be pretty happy bet calling.

Getready2rokk 11 years, 6 months ago

Q9o on 42min vs the recreational player is such an interesting hand, i always endup c/f ing turn.

Few questions:
- Would you barrel any heart rivers ? I guess its puts allot of pressure on his pps, but hes also gonna hit them with his FDs, plus do we think we can make a K fold on it ?
- Would you barrel complete bricks like 2o,3o ? Do you think he folds like 99 when we jam pot ?

Rauin 9 years, 11 months ago

MrSweets was high when recorded this. Pretty funny and extremelly informational vid! This site probably has the best GTO theory on the world, but is always good to remember that we can exploit dem fish. Specially cause I play 25NL lol
THANKS PHIL
