Stars $5.50 - Can I fold this?

[Rage2100]

Villain had seemed quite tight so this push seemed strange to me, but can I fold AK here in a $5.50? Also, should I have raised a bit more pre-flop?

First thought was easy call, however after thinking about it, his move is quite strange to call a raise and then raise the reraise, what hands do you think he does this with?

Your getting 2:1 on the call, if you put QQ (or lower pairs than KK) in his range then this is a call but if you think QQ is not part of his range more often then I think you can find a fold as you are still in good position with 1500.

Personally I still call.

Shove over from the BB to a button minraise and SB cold call. You've got really good fold equity here and the only hands you're fearing are AA and KK; if called, you've got odds to flip against anthing else and might well be dominating.

As played, call. You're getting 2.5 to 1 odds, which gives you correct odds to call against anything but AA.
