$5K trump classic

[Temp Hutter]

I will say at the outset that I am going on memory from a week ago and some details may be off a little. About 35 or 40 people left with the top 18 getting paid. Blinds are 300-600 with 50 ante. MP player raises to 2500 and both the SB and BB call. At the start of the hand MP has about 110K, SB has just under 40K and BB has about 65K. Average chip stack is 30-35K. MP is probably the chip leader of the tournament, and has been playing tight but aggressive once he enters a pot. SB has been caught bluffing recently and has been playing a few too many pots. BB is a known pro and a solid player that has been playing pretty tight lately although he can change gears in an instant.

Flop is T54 with two spades. SB and BB check to MP who bets 5K into a 7900 pot. SB thinks for a minute and calls. BB thinks for a minute and starts to line up some chips. He grabs a stack of 1K chips and raises to 20K.

MP has KK (no spade). Call, raise or fold?
