I like the idea of raising the flop to $20. that should be more than enough to push others out and charge him real well if he is on a draw. It's also small enough that I'm not bloating the pot size. If he calls, I probably check behind on the turn and call a reasonable bet on the river. If a total blank hits on the river and he checks again, I probably value bet for 1/2 the pot. This line has the advantage of not completely committing your whole stack to just a pair of queens.
