QQ hand

[betgo]

Paradise $10 rebuy, about 40% of field left, blinds 300/600/25. I am a little above average with T13K. I raise to 1800 in 2nd position with QQ and get 4 callers.

Flop is KT7,r. I am 2nd to act and check. It is checked around.

Turn is a 5. I bet 5000. 4th position raises 6000 allin, having me slightly covered. It is folded back to me.

Should I call? Should I have checked the flop? Should I have bet the turn?
