50K guaranteed TpTk vs. two unknowns ($55 buyin)

[DarrenX]

comments on all streets welcome. No reads, all stacks 3K, 5th hand of tourney, 10/20 blinds.

UTG limps, I have A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/heart.gif[/img] and raise to 100. MP calls as does original limper.

Pot 330

Flop: 5 [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img]

UTG donks 120, I raise to 280, MP cold-calls, UTG calls.

Pot: 1170

Turn: 5 [img]/images/graemlins/spade.gif[/img] K [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/club.gif[/img]

UTG bets 200, I... (?)

Actually, I'll stop here and wait for some comments. What do you put UTG and MP on at this point? Thanks in advance.
