Definately beating yourself up here is the right thing.

No brainer river bet. No one likes losing here to the moron flopping his set, but what I like doing here is if he does suckout on you here with his 62o is make him feel good about it, "man its your night, you can't miss" being positive here not only helps your mood for being rivered but encourages him going for it for the rest of the night.
