I am wondering, whether I can fold out some Ax on the river.

Even if I fold out some Kx hands, I should be pretty happy, right? And I even expect his low pairs to be folding.

What do you think? Or is the smaller sizing going to do the same job?

Ok, sometimes he traps, but what can I do right? I feel like his range is quite capped, but I might be wrong on that one. Not really sure how face up people play in MW spots.

Thanks for your input.

Not really a fan. SB is already confirmed fish after the flat in SB, you typically just don't bluff this situation.

In general, we should play much tighter multiway than hu, therefore less bluffs. Just give up flop and give up turn. Fish just might just deceide to snap with pocket pairs - which are most of his range. You could go big on the turn, big on the river to make him fold 77, but in general dont bluff the fish. And if you do, you want to block his calling range, and with QJ, you dont block any 77, 88, 99, TT... Plus we are very capped with xb on the flop, so we dont even rep anything. - which i think should be the main reason not to bluff.

if I bet river I overbet it big like 1,5x-2x
