Playing 5/5/10  

Our hand : KdKsJh9h

I open MP (3k stack) to 40 and get flatted by cutoff and hijack and button raises to 180 (1200) sb cold calls (4000) and bb cold calls (3000).

Flop:9c9d2c

Sb checks, BB bets pot. What should we do here?

I decided to pot it and get all the money in and lose to T967cc 

I know bb to be solid player and was losing at the time...he would have 4b AA9x preflop...I decided to pot it because I figured his range to be way more run-down like hand rather than A9xx hand given the cold call of the 3b oop.  He is very unlikely to have a 92xx hand imo. I didn't want to flat the flop bet with KK in my hand, seeing as decisions would get harder on most turn cards and/or lose action.

Should I play differently or chalk it up to variance/standard situation?

Thanks
