This is vaillain.
Seat 1: Player1 ( $50.00 USD ) - VPIP: 24, PFR: 19, 3B: 8, AF: 2,3, Hands: 5718
His Preflop Continuing range from Bu is 14,7% and about 7 coldcall.

He has 33% river aggression and 30% wtsd and 52%w$@sd.

My reasoning is that i block basically all of his calling that is not betting itself on the river, leaving him with a more polarized range that is rather betting than calling.

My question is what do you guys think about his river valuebet and his call. Im new to nl50 and am wondering if this is normal play. I dont get why he would use the Ac as a bluffcatcher since its likely one of my bluff combos, i like that he calls with a jack because it blocks my valuerange by 2 pretty clear combos.

Im also wondering if there are better lines to take with this hand since im crushing the board so hard and blocking his calling range.
