Dont have much info vs him(less than 50 hands), he actually folded quite many times vs me (2 small pots, and 1 medium). Probably not most agressive player, but possible varience - card dead.

Flop turn pretty sure I gotta raise to put pressure on his weak donking range(presumable for this size) and we have 2 overcards and 4 to a straight. Ohh I found out that my turn raise touch small

River Im not sure whether I should jam. Well my quick math said that i need 60%-65% fold equity vs jam.
Can be convinced that it is easy jam and he is blockbetting 8x there, which I suppose he will likely fold vs jam
