10c game: 3x-4x preflop isn't enough, as you can see. You want 2 callers max. I'd raise to .50 off the get-go.

As played pre-flop: Even at .10BB, Q2 isn't going to call a .30 raise, you have 2 K's, so K2 is pretty unlikely (K2s is a very possible call in $10NL). You should only worry about the A.

I say fire out a pot-sized bet. Since there's no draws, you'll either win right then and there, or get called, and know right away that you're behind, and can resume checking.

The way to make $ in poker is to know what's in your hand, and figure out what's in your opponent's, and bet accordingly. A pot-sized flop bet will get you the info you seek. [img]/images/graemlins/smile.gif[/img]

How you played post-flop isn't bad (minimizing your risk), just so long as you're clear in your head that you should fold to anyone who so much as min-raises you.

Did you win the hand, btw? Or was someone check/calling an A3-A6?
