turn big pot ugh

[Vehn]

somewhat interesting spot here. One limper I raise 77, bad player calls button, good player calls sb, bad lag 3-bets from the BB everyone calls. Flop 9 6 2 rainbow, bb bets limper folds I raise button coldcalls (he may possibly have something in his hand relating to this board), sb calls (he surely does), bb 3-bets we all call. Turn 8, sb checks bb bets I call button calls sb raises bb 3-bets and its on me..?
