AK preflop at borgata 5/10

[mak15]

Game is playing pretty loose passive in every seat except for one who is the 2+2er I went down there with. I've opened enough for one of the old guys to sarcastically comment that I must have a good hand every time. Most of my raises have been against limpers in position, but I've actually opened in EP a fair amount too. The reraiser seems to have a lot of gamble in him and is a calling station post flop. I don't remember ever seeing him reraise preflop in the couple hours we've been playing but I'm not positive. Villain looks to have 1600ish and I cover. Full game.

I open to 40 with AKo UTG, 4 calls around to the big blind who pops to 200, I?
