villain is 37/11 over a small sample.

river a bit thin to jam?

I suppose he could have tons of 5x combos and his good aces would 3bet pre leaving him with fewer Ax, that and I block it...if he has like QcTc though or something he binked an out on the river so those hands could make a crying call...
