there is a good chance that BU will raise again. And you need optimism that borders with ignorance to think an A and a K are clean outs here after this preflop-action. The pot is huge, but it could easily happen that the flop is capped. and even if you hit an A on the turn, you are trapped between two opponents who seem to be extremely confident about the value of their hands on that T-high flop. So fold, please.
