Betting TPTK on very scary board.

~8% in UTG/+1/+2= 10/10 (sometimes 99, 88, and 77) through AA, AKs/o, AQs/o, AJs, A10s (possibly),KJs, QKs. So you're ahead of 7, split with 2, and are behind 8. He didn't cap preflop so JJ through AA is unlikely. I figure you're ahead more of the hands than you're behind in this situation given the preflop action.
