Crooked house game, quads on flop, your move?

[Rotating Rabbit]

6max. I have played with this group once, last week, and posted a big win. This is only the 2nd hand of the night. I have 750 in front, everyone has between 500 and 1000. 3/6.

So I'm BB. SB has just come back from collecting a pizza delivery and is sitting out this hand. So the guy to my right shuffles and I notice that he's fake shuffling, keeping the top bunch of cards in the same place. He's pretty good but I spent months practicing this trick so I know what to look for. I dont say anything, and tap the deck when he passes it to me to cut. This should be interesting...

Folded to CO (covers me) who limps, button folds, I check.

Everyone is looking at me more intensely than usual. Whats my play?
