Bellagio 15/30 AA UTG

[felson]

i raise utg w/AA. a couple of folds, then i get 3bet by a 35ish muscular guy who plays like a typical player at the table -- too loose and too inclined to call down, and not unusually aggressive. i have been playing tight but i doubt that he has noticed. folded back to me. i just call. (i decided to get fancy here because it was headsup and because a 2+2er was sweating me.)

flop: KT5 rainbow. i checkraise, he calls.

turn: offsuit jack. i bet, he raises, i call.

river: king, pairing the board. i check, he bets, i call.

comments on all streets appreciated.
