opponent is aggro can be some what sticky going to the river. Is this a good spot to bluff? I figured it hits my bb calling and we do have the 8 blocker to the nuts. But he is a little sticky. So far up to this point I have not busted moves yet. Hes not a complete fish but hes definitely not a reg. He would do all kinds of raise sizes and sometimes 3b 3x and sometimes do small min 3b. Not really sure if bluffing this kind of player is good or not but I figured it was a decent spot to make a move on the turn and river bricked off not pairing the board. Should i be potting river or go for smaller sizing like 2/3 or 3/4?
