played a live tourney last night. 70 people. 10 starting stack.

hero has 8.5k at start of hand.
UTG has about 11k
MP has about 40k ( running hot, and got lucky a few times AI PF with underpair and got set)
blinds are 75/150 (no ante), UTG opens for 350, MP flats, hero is BTN and flats with

flop comes

pot is 1275

UTG bets 600, MP folds, hero raises to 1500, UTG raises 4k, hero shoves, villain calls.

should i flat his initial cbet and take a turn?

the reason i flatted 87s is UTG has shown down 2 s.c.s that he opened from EP. (64ss, and 85cc)
with that range i think when he raises to 4k, hes going to have a set, 2pr, pair+FD,pair+SD, and some overpairs.
