Villain is a weak/tightish 20/10. I expect him to have PPs almost always when he calls the flop and maybe some high Ax hands, and the board is so scary I feel im getting crushed in big pots. My plan is to check/call the turn and checkfold the river since I dont expect him to 2 barrel with mid PPs and I dont expect him to flat KK/QQ or maybe even JJ pre. goot?
