You're in a 600NL 6-max game on stars, on your left is Sauce123, an aggressive and sometimes tricky, mid stakes NL player. You are a good and aggressive but not as tricky as sauce. He views you as solid.

Folds to you on the button, you raise with XX, sb folds and Sauce123 (who is playing out of the blinds a good amount) calls.

The flop is 994 rainbow. sauce checks to you, you cont bet, he c/r 3x.

I really really really just don't get this spot at all. With a straightforward abc tagg it's easy: this is usually a 9, 44, or utter air, and i can play accordingly. But with good aggro players, or just aggro players in general this becomes harder because this isn't a 9 enough to safely fold medium strength hands.

so, questions:

- what range of hands do you put him on?
- what hands do you continue with and what's your plan?
- how does this change if i'm on the CO and he's on the button (he has position)
- how does it change if the board is QQ5?
- how does it change if the board is 339?
- how does it change if the board is two tone?

Ok too many questions, feel free to just say anything you want on this matter.
