I was going to open push the turn but thought that villian would bet scared and give me better odds, im thinking he has a 9. i'd be calling 3855 into a 8655 pot. or 2.24 - 1. If my J is good as an over (say he has 9,X) how does that, coupled with the player already all-in, make this a fold/call?

equity (%) win (%) tie (%)
Hand 1: 40.3030 % 39.70% 00.61% { Jh7d }
Hand 2: 59.6970 % 59.09% 00.61% { Qs9h }

i'm thinkin it goes something like this, but if he only has a 7 im way ahead bc of the nut straight T outs.

your play and why? thanks- </font>
