Preflop looks good, maybe I'd raise to 20 if I thought he'd call with enough mediocre hands.

Here's some advice from Super System: "Anytime there's three cards to a Straight or Flush, I play the hand with extreme caution. The quality of the possible straight that's out there also has a big influence on the way I'd play that big Pair. If it came 9-8-7 or T-9-8 or J-T-9 and I've got two people in the pot with me... I immediately give it up."
