What do you think of the 3-bet? What if I get 4-bet? On what river cards should I bet the river if he just calls the turn 3-bet?

3bet = good because his turn raise means so many things and rarely means that you're behind. 3bet it for value and to punish him for semibluff raising or raising for a free showdown.

if he 4bets i call and check call the river and expect to lose almost everytime. you have a few meager outs but more important is the meta game stuff.

i'd bet any river.
