[BluffTHIS!]

You do NOT just want to smooth call CO's raise in worst position in a 3 way pot. You could indeed consider it if you were going to be headsup and had position. You should reraise every time here 3 way with worst position or you will be a guesser on the flop unless an A comes, leaving your really best option assuming that A doesn't come to be pushing in front or checkraising-push, which may well be falling into a trap. Always remember Doyle's advice that AA/KK are mainly for getting allin preflop (or close to it which reraising to like 360 would accomplish forcing you to call if repopped), and that otherwise you will usually win a small pot or lose a big one. Bad position is not a place to be trapping preflop in nl especially if not headsup (unless at a very shorthanded table).
