annoying hand featuring the soap

[Vehn]

Its my last orbit and I like to gamble so I limp along in MP after utg limps with the soap - 9c7c. Button (sayid) raises, he is awful, usually loose passive but prone to fits of pure retardation. Terrible lag calls in the SB BB folds.

Flop Ad4c2c, checked to button who bets, SB c/r, utg calls 2 cold, I call 2 cold, button calls. Turn 7s checked around? River As checked to me I check, button bets, SB insta calls, utg folds, I fold?
