I'm raising pot pre-flop. If a loose-aggressive player is gonna play back at me, it's gonna cost him. On the flop, I agree with either check-raising or folding. Yes it's 2 queens out there but the fact remains that you still only hit the flop 1 out of 3 times. If he has a diamond draw, well make him pay for it. Giving him the lead was probably the worst in this case because now, you don't know where you stand.
