[taipan168]

No reads but MP3 appears to be a donk. What's your turn move? How is the turn lead?

Nice turn lead. Don't want donk minbetting again. Rest is Weird. Obv button is committed so this is a decision for 1140 chips.

You know I look at the hand and all I can think of is reasons to fold.

I know MP3 min bet is dumb, but he still is leading into 4 players on flop, and he's not afraid of the A. And WTF must the button have? Why would he flat instead of shoving over? AQ, AT? In a $27?

Dodgy. I and I don't want just TPTK when things look this weird. Having said that the odds look tasty.
