First, I would say 140 hands is a bit light of a sample size, but it's better than 50 hands. I wouldn't trust the sample size completely, but I think we can still draw conclusions about his playing style.
These spots are tough against passive players. Their 3 bet ranges pre-flop can be pretty small. He doesn't reraise me on the flop. I think his turn donk still has a relatively wide range. Could be 1010+, AQs+. I think they're more combinations of his holdings which I can raise profitabily. So I raise. And I'd call down if he 3-bet, though I'd hate it.
If he was a good player I might just call, since he could 3-bet the turn, this is a good play against a super aggressive player, or anyone who raises the turn often, to donk the turn and go for a 3-bet.
And the general line doesn't make much sense for aces. 3-bet/call cap, bet/call, donk bet. Really?
I laughed after he showed aces, pretty strange. If you're that scared of QQ to raise in this spot........
I guess I felt he was going to show me AQ enough of the time for this to be a value raise. I understand the argument for calling if he's donking AK or medium pairs, but I thought even with those hands he might call down a raise, and the the second 6 puts a backdoor flush on the board, however unlikely that is.
Thoughts?
