You are in a large tournament with a significant buy-in, the player to your immediate left is a solid tournament pro. The bubble is coming soon, and you have 30 big blinds in your stack, a little above average for the tournament. you raise to 3x with QQ after the action is folded around to you, and only the pro to your left calls and he is on the button. When the flop comes 3-7-9 with two hearts, you bet 5 big blinds, or about 3/4ths of the pot, and the pro moves all-in. You have 22 big blinds left and he has you covered. What is your move?
