Preflop and flop
Pretty standard not much to say here.
Turn
Betting here is a pretty standard TAG strategy, but I would not be surpriced, if solvers wanted us to check TPTK a decent amount of the time. The reason is, it sucks getting raised, which is exactly, what happen. We did bet though, and I would also do that as a default, we did get raised, and now we need to make a decision.
Its a classic Baluga theorem spot: "If you are heads up and facing a raise on the turn, you should reevaluate the strenght of any one pair hand." However in this particular situation, its very unlikely, 2d made him a hand stronger than one pair. Did he call us on the flop with 22, probably not. And even if he did, its only 3 combos. Call us preflop with Q2 or T2, also probably not. And if he did, probably only the suited combos, which again are not very many.
So he is really saying, that he sandbagged two pair or a set on the flop. And on such a drawheavy board I think, most people would fastplay their big
hands and raise right there on the flop. So what this looks most like to me is a draw, most likely backdoor diamonds. And therefore I am calling this all day and also calling again on most river cards, that dont complete the backdoor flush.
I quoted the Baluga theorem, because I think, its an important one, but I also think, online games have gotten much more aggressive, since it was written. And I think, that if you bet-fold TPTK on the turn, you are just bet-folding way to much, especially since he is also giving you a pretty good price of more than 3:1.
