Just want to mention to OP that 20 hands on a villain is not nothing for PF stats. It makes a difference whether he is 10/10 over 20 or 60/5 over 20. So give his stats.

Also KQs is a perfectly good hand to raise, even UTG.

Alos, as mentioned above, make an effort and go through the process of putting your opponents on street by street ranges.

Finally, if you insist on playing with $1.40 stacks, at least auto-reload to that amount. But honestly at 2NL you're better off playing full stacks and a low variance style (aka nut camping, set mining and very large amounts of folding).
