Why does he raise only 400 from the BB with 3 other callers? Then he (slides = all-in right?) push in front of 3 players. He could have set up a bluff but not very likely.

I put him on AK, QQ, KK and AA.

You beat AK and AA but not QQ and KK.

AK = 12 combos (60 - 40 ahead)
AA = 6 combos (60 - 40 ahead)
QQ = 1 combo (drawing dead)
KK = 3 combos (drawing dead)

Overall : 49% - 51% behind. This call is even money plus the pre-flop bet, so it is a call.

Players left, Payout structure?
