AJ in first position? i'd raise from the getgo.

but assuming i didn't and we both saw the flop, i'd raise at that point anyway. if anything, that'll force him to call (or raise) and it'll tell me that he got a piece of that flop. and that way, i won't have to lose any more money.

of course, i'm assuming this person is playing pretty tight. obviously ur style of play changes depending on who u're in the pot w/.

the guy raised w/ a 2,4 preflop b/c he thought he sensed a weakness. last position always has that advantage. u calling that preflop raise prolly let him kno that u definitely had some nice high cards. yes, he did get "lucky" on the flop but that's b/c u gave him the opportunity to do so. so the question is, if u came in first to call and raising preflop, would he have folded?
