$55 Party 2 table, KQs hand

I had won a couple of recent pots preflop w/o showing. BB in this hand is somewhat tight.

Final Pot: t3740

After my raise and his push, it's a pretty easy call getting 2 to 1. However, do you push preflop, raise more than to t550, raise less than to t550, limp, or fold, instead?
