Yeah it is a tough spot, while villian may not bluff raise on the river there's a very good chance he'll call with any heart in his hand (since it is cake).

I'd say it's a thin line either way, honestly I'd probably play it the same. I'd have a tough time firing here. Even if we don't get CR he could have any random heart in his hand and then we wind up taking ourselves to value town giving him an extra bet for his janky flush.

There is no way on gods green earth that a cake mizor folds a heart there. No way. Not. Gonna. Happen. Ever.

Yeah growlers, i donno dood... I see where your comin from here, but (a) these players dont laydown like ever, but more importantly, the way i looked at it is if he called the turn with some sort of heart draw, he obviously didn't intend to fold it on the river. ash Games
He couldve had a ragged ace with like the i guess, which he could laydown (maybe) but i really didn't think he had the ace because he played his hand way too passively..no raise PF or on the flop...And even if he did have , i think he very well might call, for the same reason that i didnt valbet, which is cause im repping some sort of made hand on the flop , so theres less of a chance that i have a heart (thats fair to say i think?) and thus hes prol more likely to call me. Put another way, if I was him and i had a micro heart, i would be very inclined to call my river bet, figuring there was a good possibility that someones trying to valtown me with like aces up/set/etc...

I figured if he was on some sort of draw that didnt involve a heart, hed have laid the turn down, and if he did have a draw involving a heart that he thought was good enough to call the turn with, hes not folding the river...thats the best way to describe my thoughts i guess. 4h5x is like the only hand where he might have a draw involving a heart where he MIGHT (prol not still) lay down the river... but that is a pretty donktastic holding first off, and a pretty ridonkulous turn call if in fact he intended to see the showdown only if he made his straight and not if he made his flush.

He actually had 4s5s, which was also a pretty donktastic holding in this spot...

Anyways, i am not at all averse to valbetting on a four flush board without the flush in alot of spots, like when it seems like mizor had a made hand before the flush cards came out, and i think i have a better made hand...here tho, i dont like a bet.

It's difficult to zero in on the % of a fold with a heart here, but its not 0......I don't think anything ever is 0. Sklansky speaks of assuming 10% as a fair chance of a bluff when thinking of calling, so that may be a good point to start since its non-zero but low. I don't know that I would put it much higher.

Interesting point to consider. Growlers, you say "if the pot was 1000 BB then clearly betting is correct", but I think this is counterintuitive. There comes a point where the size of the pot makes it ever more unlikely that the weak heart will fold and therefore we hit a point of diminishing return. I think there is a sweet spot for a bet here which lies in the "slightly above average size pot" where its just not quite big enough for the weak heart to call. Clearly you would not fold in a 100Bet pot if you held a baby flush and were facing a single bet.

yeah anteyes right. I tookim 700 posts, but hey, better late than never! The bigger the pot, the less of a hand the mizors will need to look you up, id think, and the smaller the pot is, the less the mizors will think its worth it to call with somethin crappy..

This is one of these weird situations, and i always had a hard time understanding this, but i know some high limit pros, and they have espoused this before, namely the 'dual prupose bet' ... because its possible that either (a) youll get called by a worse hand or (b) youll fold out a better hand. To me, these two situations are so disparate from each other, it almost doesnt seem fair to justify a line this way...i mean, if your acknowledging it can either be one or the other, your basically sayin 'meh i have no idea where im at in this hand, mize well bet i guess...' ... i dunno...maybe this way of lookin at it isnt that bad? i dno...ive always had a hard time with the whole 'you might get called by worse or fold out better, so bet' theory...
