Borgata Poker Open: can you get away from this hand?

[giverofbadbeats]

i have about 650k in front of me, which is about 2x the chip average at this point in the tournament, which is near the money bubble.

blinds 5k-10k with 1k antes. folds around to me in the small blind with 10c10h. i raise big blind to 30k. bb is mark seif, who has a similar chip stack, makes a comment about why im making such a big raise and calls me.

flop comes Jd 9d 5c
i bet out 50k and he calls quickly
turn is 6h
i bet out 75k and he calls quicly again
the river is 10d
i check and he bets 150k.


i call and he shows 7d 4d for the flush and i lose a 500k+ pot. is it possible to get away here or does a fold just cost you money? try to imagine that you DONT know the result. lets hear your thoughts
