KK or QQ with overcard on flop

[JMT23]

I would say raise in that situation. If you get reraised then you can fold. Its all about what you know about you opponent. If he is a good player he will raise to see where he stands. You also have to keep in mind of the cards he has been playing. Does he raise everytime he has the goods or does he play the Ace 9 off suit like a lot of reckless players. If he calls you, you still have a chance to get your set on the turn or buy the entire pot with an aggressive bet. If your reading your opponents correctly, then it would depend on your chip stack.
