villian unknown to me, first or second orbit from him, but i have 80 hands from him
22/16/6.5/45

normally i cbet this on the flop, but dunno i put him on a high pp cos he called it preflop and it seems he is preflop solid from stats
so i checked to get one of my backdoordraws or AK hit
i was sure he will at least call my bet anyway but dont know if its so good to check behind
played it really weird
but 45 wts is so [censored] high to cbet against
on the turn i got nutfd+ 2 overcards so i called
perhaps a raise on the turn is better after checking the flop, so he thinks that i want trap him..

dont only say what u would do on the river, say what u would do different on the whole hand
