in a 1/3 plo game, how can you raise to $50 after a straddle and a couple of callers? (1+3+6+6+6....pot raise is $34).
also, you don't really have a big pot hand preflop. yes you have a suited ace, but the gaps are pretty large. you crushed the flop (aces up + the nfd !!) (and turned a bad gutter), and you're not sure about how to proceed. it seems you would have rather played a smaller pot, which could have been accomplished by not raising pre.
as the previous poster said, what are your positions? is the villian in the blinds or on the button? are you in middle position or co?
