complain to the dealer that the deck is irregular because there are two jacks of spades
but seriously, here is the math if i did it correctly:
turn pot before bet: 212
villain left before bet: 477
turn pot before you make decision to call or fold: 779
to call: 387
so pot odds are 387/(387+779)=33.2%
if you somehow had the flush draw (let's say flop Jd7h4s, turn 9s) you have 29.7% against random T8. so, it would be a disgusting fold if he only raises the nuts.
