Villian was a tag and I put him probably on an overpair to this flop with TT/JJ/QQ soI didn't discount my overcard outs as much as I usually do. I went with 9 outs to the flush and about 4 more for my overs for about (13*4)52% winning chances by showdown.

Is this push standard and do you guys come up with similar numbers to what I did?

Thanks for any info.
