there's more here than apparent on first glance. i think all three hands are a reluctant fold - IMO, they're essentially equal here, with this action. if you look at the board (as i'm sure you're implying from this question), if you held 10c8c the only likely flushes he could have would be the nut flush, Kc9c or AcKc (both of which he would have most def bet the flop), 6c5c (of which he would have definitely bet), or 4c5c (same). Sets and two pair would have also bet the flop, as would overpairs. So you're either up against AcXc, or Ac10x, or a bluff. His hand range is very slim, for sure.

i don't think he's calling the turn to bluff the river; i don't know if i've played with him, but i assume he'd raise the turn if he were bluffing - mainly to define your hand. there's no way he knows that you don't have a flush yourself. so in the end, i'd give him credit for the one or two hands he could possibly have that wins, especially since you guys don't get too out of line with one another.

to sum it up, when he raises the river, you're f*cked
