Villain is 31/10/52 (67 hands), on this table I have seen him take the line of check-raise flop, overbet turn with a set out of position (that's how he got so deepstacked) so I think it is very unlikely he has the set.

On flop I do not raise because his range has no draws in it. I think I can afford to just flat call and give him a free card, because if I reraise here I think I kill my chances of getting it all in, I think he has AK, QQ+ at this stage and want more value. AK will maybe call reraise but later street action will be problematic unimproved and so deepstacked so I just call.

The turn I feel like he has AK, so I just flat call. Maybe I should have reraised here, but I doubt he's on a flush draw, and 7 of diamonds is magic card for me anyway. My plan if a diamond pops up, just flat call or fold depending on how much he bets. And if diamond doesn't pop up, I jam it and it can maybe even be interpreted as a missed draw bluff or AK or worse two pair.

River is blank as it gets, but his bet is quite big, I'm thinking he either has 2 pair or was getting tricky with a set and I almost didn't have the stones to shove and was instead going to flat call. But I stick with the original plan and just jam and shit pants when he snap calls until I see his cards.

Thoughts? Was by far the biggest hand of my session. 100bb stack would play it a lot differently, probably try to get it in on turn. So yeah probably what I'm asking is should I a) reraise turn? and b) should I have flatted the river instead of jamming, results aside?
