Stupid call?

I was playing my first MTT on poker stars earlier today and this happened...

First, a little background info on the hand:

The guy who raised my 400 was eager to leave the tourney. He wasn't playing like a maniac, but he was making a lot of loose calls.

After he won the hand, he even said he had to go, and just pissed away his nice stack a few hands later.

The hand (poker stars doesn't give you the hand history for freerolls, so I'll try my best to recreate it from memory):

Guy 1: ?? (I have him covered by about 900)
Guy 2: ?? (chip leader)
Me: QQ (about 2,000 chips less than the chip leader)

Guy 1 starts out with a 120 bet into 15/30 blinds.
Guy 2 calls
I re-raise to 400.

Everyone else either folded to his 120 bet, or my 400.

Play goes back to Guy 1 and raises all in. Guy 2 folds, and after thinking a little, I called.

So, I put him on AK or maybe AQ/JJ, thinking he would have either limped or raised harder with KK or AA initially.

Now I realize AK (especially suited) dominates QQ, but since he was playing the way I mentioned above, I figured he might just have any semi-decent hand.

He flips over AKs (spades).

Flop comes up with 2 spades, and a rag -- no face cards. Turn is another Q, and then the river brings a spade.

So, was it dumb calling his all in? The more I think about it, the more I think it was stupid. However the pot was real big, if my set held up, I would have been in a very comfortable position chip wise.

Also going all in with suited high cards is risky pre-flop no? It's very possible to beat it with a ton of hands, which also made me push call. Or am I thinking incorrectly?

Early in MTT, I dont think you want to do coin flips or even 60/40 flips. From what I have been reading, your objective is to:
(1) Survive
(2) Build chips slowly
(3) Go all-in with nut hands (maybe semi-nut)

Along those lines, I would only consider the all-in with AA. However if the call isnt a big percent of your chipstack, I would also consider.

As a note, I would do your play in an SnG maybe.

blinds were 15/30 so this was early in a freeroll tournament? Good call, bad community.

If you had been close to the money, or if you had been heavily invested in this tournament, you might want to be more timid. Or if this was a very tight player, and you knew he had something big, you may want to fold. But in this case, he was the chip leader, so he had obviously been playing a lot of hands, and he's probably pretty loose, so you can't put him on AA, KK or AKs with any certainty. Think of how few hands beat your QQ. In your situation, I'd call it all the time.

Hmm, he wasn't chip leader. I had a bit more than him, but he wasn't in a position where he had to double up to survive.

And yes, it was early on -- I think it was about 15 minutes before the 1st break (pretty sure they break every hour).

I haven't read any strats on MTTs. I figured it was good to get a nice chunk of chips early on because the blinds do catch up if you play super tight/timed. Having about 1500 chips or so when the blinds are at 50/100 and everyone else at your table has 3-5x your chips is not good.

I will try to play a bit slower next time (poker stars rocks, with that hubble freeroll going on pretty much every day).

Now I realize AK (especially suited) dominates QQ, but since he was playing the way I mentioned above, I figured he might just have any semi-decent hand.

this is untrue AKs 46%/ QQ%54

much like a coinflip.

AK vs QQ is a classic.
