first time i play against opponent, i sharkscoped him and he is fishy .. 50 games played, 5$ av. stake
i called his 3x raise OOP a lot before and i c/r his cbet 3 times so far the same amount as in this hand, all of them succesfully as he folded. it's still early in the match but when i showed weakness in previous hands he seemed to take a stab. i feel he has had it with my check raises and he is calling ATC my c/r. turn is very ugly and i check to induce bluffs rather than bet/folding with a plan to c/c river as well.

thoughts ?

Raise the flop bigger, ~t220.

As played, we probably can't fold to a river shove that small. We're slightly behind here IMO, but we only need ~25% equity to call profitably.

That turn card is as ugly as it gets. Given your high check-raise frequency we have to assume all aces are still in range. On the turn I make us about a 52% favorite against his flop call range. I've included a few king high hands as well as almost all pairs (flopped or pocket) in his range. Once he bets I think the likelyhood of him haveing a weak pair or king high is far less as most villians would check behind with weak showdown value.

I don't think we are enougth of an underdog on the turn to fold, unless you really have a huge edge against him, but I think we are going to be behind way too often on the river to call.
