This is mostly a maximizing extraction question. I think I should have be a little more on the flop and the turn. A check behind standard?

Flop and turn, I like from a pot control perspective. Against an opp this passive Ax is certainly there, and he could be slowplaying AJ just as much as having A5. T9 certainly fits too. Weird line, and its really tempting to value bet the river but I can find a check behind here.

i cant tell if villain is just donking up an A with a decent kicker, or if he is slowplaying a flopped 2 pair. I think he would have c/raised the turn with 2 pair. i think i throw out a $7 bet here.

I vb the river cuz he will call with less. Bet $5.55.

FWIW he thought for awhile before calling my turn bet
