Hi guys, i'd never played against villain before this session since he's a reg of higher stackes(400+) so i suppose he's at least a not bad player almost certainly better than me. I normally play lower stakes mixing up 50 and 100. i sometimes take a shot at 200 when i see that are seated the same big fish that i play against at my stackes. Anyway going back to the hand i had only 34 hands against villain and he was playing 38/18/1,6. went for a ck/r because i was quite sure that i was going to cbet that flop (giving that he cbetted three out of four times) but when he repot i put him on some big wrap than my plan was to call and push any river card that was 7 or lower. what do you think about the whole hand??from the preflop..is it playable hand OOP against a button open?what about the ck/R at the flop? should i have folded to his 3bet??
