AK preflop, early in one table tourney

[cha59]

Did I play this correctly? I need some feedback please.
Poker Room, $10 + $1 single table tourney, very loose table - lots of bad cards being played, first round,
$10/$20 blinds, all (10) players still in, $1500 avg stack.

Hero holds AK offsuit in small blind, $1490 in stack
Four calls, Hero raises to 230T (pot was 110T)
MP 1 raises to about 835T (all in)
CO + 1 calls (he has about a 2000 stack), others fold, Hero raises to 1500T (all in) (was this a good play, or should I have folded here?)
Co + 1 calls
Results later

I rarely fold AK preflop at the low buyin SNGs but I think you absolutely have to here. MP1 limp pushes, which indicates a pretty powerful hand. Then CO smooth calls a massive raise after initially limping. If CO doesn't want action he just pushes. One of these jokers has KK/AA.

Also, I raise to 140 PF.

Those thoughts went through my head before I reraised, but because of the loose play I saw before, I reraised anyway.

The joker in the MP had A2 offsuit, the idiot in the cutoff had 72 (he called my all in w/72!).... Of course I lost this hand or I wouldn't even be asking about it. A 7 and a 2 hit with no aces or kings.

Regarding raising to 140 preflop, I normally would have raised 120-150, but I read some posts on 2 + 2 saying when you get in a loose game like that at low limits, it might be better to raise about twice the size of the pot. You sometimes get loose calls out of it.
What are your thoughts about that?

Generally, I don't want to play a big pot with AK out of the small blind. You always have to consider position...

Good point, thanks for the tip.
