Tough spot. Although he has a flush a lot, you beat pretty much every other hand he could hold, and by checking the river you broadcast that you don't have a flush. He only needs to not have a flush about 1/3 for a call to be profitable.

I call here since 2/3 PSB on the river is a pretty big value bet when it's clear you don't have a flush so I expect his bluffing frequency to be higher than it would with a 1/2 pot sized bet. Also, winning drastically improves your chip position, and although losing hurts bad, you still have 13BB and 30 minute levels so you're not crippled.

I don't like that you say "no special reads about the player," though -- 5-handed at the FT of a deepstack tournament you really should have some kind of read.
