Hello.
Oponent is 26-23-14, AF:2,3, W$WSF:55 (only 66 hands). After i get raised in the flop, I'm not sure what to do. If he's semi-bluffing and I just call, I'm giving equity away.
So I decided to min 3bet: if he has a FD, he could call for odds but I'm happy I made the pot bigger. If he has a total bluff (unlikely but possible) he should fold. He could only raise with sets or maybe AK, and I block AK very heavily, so when he 4bets, I have a fold.
For some reason, though, I don't feel my thinking is right. Any thoughts? Thank you very much
