party 30-60 river plan with a boat. . .

[mmcd]

It looked like BB bet out and called 2-cold after SB check/3-bet the flop. I think AA is fairly likely here, but it certainly isn't impossible for him to have AK with a club or 2, or KK on a wonky free-showdown attempt. Calling the river (and his checkraise) is probably better here, but I don't think it matters much. I'd still 3-bet the turn though and call down if capped (with UTG calling along, I think you are missing significant value by not doing this). That game is certainly aggro enough that I'm not looking to save bets with a boat in this spot. You have enough of a hand that 5 bets on the turn/river is probably right around where you want to be, but given that bb may well fold the hands you beat for 2 cold on the river, why risk the 3-bet?
