I should have folded, but I couldn't

[ilovethisgame]

6-max, $300 buy-in, blinds $2/$3 at bodog.

I'm UTG with A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/diamond.gif[/img].

I raise to $11. Get two callers.

BB checks. I bet $35. Initial caller calls, BB miniraises to $70. I call, so does initial caller.

Turn is another A.

BB bets $130. I don't have enough to raise so I just push allin for $300. Instant calls from both.

River - A.

I make 4 of a kind and take down 88 and 99.

Would you have folded?
