This is rough. I do not want to give chips to a player like Duhamel, and he looks really strong here to be honest. He never makes this move without a stong-ish range. I think AA, KK, and AK are strong possibilities. He also has tons of draws with overs to you like QJhh, Axhh or even KQhh where he already has you dominated. You are only getting 2 to 1, and I think we are just behind. I hate it, but I may fold.

Also, I much prefer a flat pre. You mentioned the BB only has 8k. If he shoves, duhamel is handcuffed and can only call with the top of his range, when he calls you can set-mine/fold, and when he folds you have an easy snap call. I don't think Duhamel is folding the button that much to you, and I prefer to 3bet different types of hands against him. I would probably play 9s for set value only, with the exception of some dry boards.

As played, I still c-bet he as to fold tons of hands that he calls 3bets with.
