Great Knockout-- Did I have Any Choice?

[oaktoon]

live tourney-- 5 hands into a final table. I had no prior experience playing either of the two in question, as we had been at different tables all night.

Roughly 45K total chips. I am in 3rd or 4th place with approx. 5500; one stack is about 7500 and another 8500. Tourney pays 4, but needless to say, i am not playing for 4th place.

Blinds 300-600.

I am UTG and dealt AKo. Previous initial raise at this blind level had been 1500. I raise to 2000.

Fold to MP2, who has biggest stack-- he calls;

Fold to SB, who is short stacked with about 3800 chips. He pushes all-in.

I call, big stack calls.

Flop is 3 rags with two clubs. I check, big stack puts me all in. i call.

Hands shown; me with AKo; big stack with AKclubs; Small blind with QQ.

You know where this is going, right?

No ace, no king, no queen, club on the river and big stack knocks us both out.

Critique my play.

I could have limped, but at that stage I wanted to isolate somebody or steal the pot, and not get into a multi-handed pot.

I could have folded after the QQ went all-in, but I was pot committed and that call still left me with 1700 chips. I read him for a smaller pair so I knew it was pretty much a coin flip. i read big boy for AK or AQ all the way-- and even with the threat of a flush draw, i don't see how I fold after he pushed me.

Thoughts??
