This was a definite reraise on the flop. You made trips, you have to play that hand really strong and punish him for whatever he came in with (possibly overcards!) You're winning against ANY hand he came in with right now.

The 7 doesn't threaten you either. The board is semi-coordinated, do you really think he 3-bet PF with something that is helped by the 7? Good job capping.

Good river. I say you missed out on the flop, but maybe you felt like you could wring him for more BB on the turn if you didn't scare him on the flop first. I don't play 6-max so maybe that is a good play there.

Otherwise well done.
