Two 25/50 QQ hands

[Ulysses]

Hand 1: 6-handed. 7k stacks. I have been playing pretty aggro. Tightish, somewhat aggressive but not overaggro player opens for 150 UTG. His opens range from 125-175 pretty randomly. Caller. I make it 650 in CO w/ black QQ. Opener calls, caller folds.

Flop 2s 8h 9h : Check, I bet 1300, he checkraises all-in for 6400.

Hand 2: About 15 minutes later. 5-handed. 5k stacks. Same guy opens for 125. I make it 425 in SB w/ QsQh. He calls.

Flop 3d 5h 7s : I bet 900, he minraises to 1800. What's your plan? If we know what he had last time (set, flush draw, or pair hand), does that make a difference in your plan?
