Plan On River? Opponents haven't gotten out of line yet, and it looks like atleast MP1 has a boat.

Comments on other streets appreciated also.

Check and call 1 bet.....You are probably fine until MP1 caps and the Button calls the two back to him........If Button and MP1 get into it on the river, I'd lay it down with confidence, but pay one bet for sure.....

I'd have to say that the range of hands MP1 would play like that are fairly small...He could have been looking for overcalls on the first two streets, so I could see him playing K [img]/images/graemlins/diamond.gif[/img]10 [img]/images/graemlins/diamond.gif[/img] like that, although it's more likely that he flopped two pair, filled up on the turn and was waiting until the river to come alive, but decided no one was going anywhere, so he pushed.....The BB probably has a single jack here, I don't think you are behind him...
