I didn't see any merit by betting on the river because I thought that he will only call with hands, that beat me, like a better flush or a full house.Maybe trip Kings, but thats it.By hindsight I am not sure if I should raise all in on the turn, considering his stack size and his range, which I assumed is on the flop any broadway heart, any set, bare nut straight and maybe a (better) flush. And of course some random bluff.
