Please analyze this?

I was playing in a tourney last night, doing okay when this hand occured: I have 4350 chips, about 50th of 80 remaining, blinds are 300/600. On the button I am dealt Ace of spades, Q of hearts. There are two callers before me (from middle positions) who both have me covered. I flat call, and both the blinds play. 3000 in the pot, and the flop comes Q spades, 10spades, 7diamonds. Everyone checks to me, I go all in for 3750. 1 caller from middle position using 60% of his chips. he turns over K5spades on the flush draw, which he naturally makes on the river! a) Should I have gone all in pre-flop? b) Was I a bit rash shoving all in when I did? I'm not sure how i should have played this. Any suggestions would be invaluable.

Re: Please analyze this? M of just under 5, I'd say you junk or shove, depending how tight you think the players before you are. Unless they were REALLY tight I'd personally have gone all-in, and prayed there wasn't a premium pair or AK out there... That said, the flop all-in looks fine to me. Gotta try and chase away the guys chasing the flush, and it looks big enough to do that on most occasions - obviously not this one, but some people will call anything!
