Some pre-flop thoughts, is cold calling here okay?

I was wondering about this when you get a fairly strong hand on the button or CO with an uber donk in the SB. Do you just flat call a decent players raise to keep the uber donk in or re-raise for equity.

Today iPoker 2/4 6max

I am on the button with A [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/diamond.gif[/img]

The biggest fish ever is in the SB, another big donk is in the CO but not insanely donkey (lets say average). UTG+1 is decent, but over-aggressive. The BB is very weak tight.

UTG folds, UTG+1 raises, CO donk calls, Hero cold calls??, uber donk calls, BB calls.

Thoughts on this would be appreciated, thanks
