Villain is reg and plays a bit moneyscared/nitty at this limit. It's possible that he's valuebetting the River quite tight for this particular sizing.
I know solvers want to x/r bluff in that spot with hands like K2s and mix fold/bluffcatch with KQo. But bluffcatch is not an option vs this player since I have the read that he's most likely underbluffing hard. So I don't want to block 22 which could be part of his folding range and all the straights.
thanks for opinions in advance
