This was a hand that i had a discussion with opp with afterwards. I'm interested in what people think opp should call with and why.

Redgrape has been threebetting me light, It's obvious he realizes im raising a lot from the button and has raised this same amount several times. Nothing has shown me he's a big thinking player, but he seems solid.
