re: Poker & $25 NLHE 6-max: $25 NLHE 6-max: River spot
Looking at his stats and stack size, he is clearly a fish. Fish do not hand read and say, "Oh! He might have flopped the nuts with 56s from UTG!" They are probably not that positionally aware, and anyway almost never is 56s opened from UTG. That is way too loose. And fwiw, I'm pretty sure that's the last hand a fish or a reg would put an UTG raiser on on this type of board.
When a fish has a good hand that he likes, he's going with it no matter how much strength you show. He might be slowplaying a set due to his passive stats, not because he's afraid you flopped the nuts with 56s. But 27/9 is not that passive. I'd be more inclined to jam if he were a whale with something like 65/10 or 65/5. Anyway, I'm getting in even bottom set on this board vs UTG OTF or OTT; people stack off way too light with overpairs at these stakes.
When you jam here, what exactly are you getting called by that's worse? Maybe a stubborn JJ/QQ, if he didn't 3-bet it pre and feels committed. He may be a fish, but he's folding out all one pair hands unless he's feeling really frisky and going to try to hero you with 55/66/99, which are reasonable hands to call down OTF/OTT with given his stats. He has gs + 2 outs to three of a kind. You are crushed by 56s and J9s, and by 1010. KK too if he's really that passive, but even most fish
3-bet that pre. He's always calling with flushes, which make up a decent portion of his range. Also, because of the board and your hand, you pretty much block all two pair combos he could realistically have: 78s and 108s.
I think I prefer check-call a little better, but jamming probably isn't that much worse. Check-calling at least gives him a chance to bluff at it, although I don't really see that many bluffs in his range at this point other than 55/66. If you really think he's jamming all combos of flushes, 2p, and sets, then you should check-call instead. Now you get value from 2p, lower sets, and bluffs. As opposed if you just jam, you only get value from 2p and lower sets unless he want to try to hero you with a one pair hand and just doesn't want to believe you. But as stated earlier, 2p is really unlikely on this run-out due to blockers, and lower sets/JJ/QQ really should have gotten it in on a wet, connected board OTF or OTT.
What did he have?
