$8/fold

$8/fold

These inducing sizings and then folding tilt me inside each time I read them.

I'd rather $20/fold.

I'd rather $8/shove with a boat here, just cause I expect to get raised by Qx and raised as a bluff, since I don't think ppl expect us to bet Qx like this.

You just want to be exploitable in every single spot don't you griffo?

Turn bet is too small when he has so many pair/gutters. River spot confuses me. I don't see what Qx he could possibly have that is too weak to iso a 40bb donk pre, but strong enough to overcall a 3 dollar raise.

Needless to say I think its really hard for him to have a queen, but its also really hard for him to call a bet with worse, and he has little need to bluff when checked to. Given that I think I would take pocketfours's line. He can't really have any pure bluffs.
