So my thinking on the checkdown was: Check on the turn to keep the pot small, since he raised, then on the river the flush draw came in and I figured the only think I'm beating is a smaller queen, so I just wanted a showdown.

My question is: Was this line decent, and is it smart to reraise him on this flop?
