Flush on the River (cash)

BAD BEAT

I was a 95% favorite on the flop and it was my mistake not to make my opponent pay more for a card on the river. However, I was still an 82% favorite on the turn. Another mistake I made was raising on the river. I wondered if my opponent had made a flush on the river and my greed led to my raise. I could have folded but the raise was perfect on my opponent's part. I had to see it.
