Info on villain -
Mid 40s, the type of guy that likes to gamboool, had previously seen him oversize x/r to a utg open and cbet on ATTcc board and call off a shove with j2cc. He then moved table and came back later, few hands in he limps qq utg gets 6 limpers flops top set an checks, I led turn and he just called with a fd on board then v bet the river when the flush hit with 4 people still in the pot. He is passive preflop and only gets aggressive when he either has the nuts or when everyone shows weakness and he usually goes for a pot sized stab.
OTTH
£1/£1 at quite a weak table. Weak reg limps mp I iso 53s on CO to £5 an get 5 callers. Flop comes down 2d4c6d and when it checks to me I bet 15 into 25 and villain calls and original limper calls. Turn 6s. I bet 45 and villain calls, original limper folds. River Ad. I check and he pushes out a huge stack of 5's for a £125 bet without really thinking about it too much.
Final board is 2d4c6d 6s Ad
OTT I thought his range is all 6x, boats and a few combos of fd's like 85dd, 75dd, and diamond broadway combos. I thought he's probably fold things like 77-99 to the turn bet but I couldn't be too sure about that.
Given what I thought his range is I ended up folding river as I couldn't really find a hand I was beating that would choose that river sizing unless he's overplaying something like 67 or 68 which is possible but doubtful.
Long term I think this is a good fold vs this type of player by I need some validation... Thoughts pls??
