Seems to be all the rage now (even with "solid" players) to limp AA and jam the pot on every street. Happened to me the other day where I limp A9, flop was A 9 7, and I run into heavy resistance on every street. I put him on a set of 7's and the river is a beautiful 9 and we get it allin and he flips AA. I say "Rounders" and the table cracks up...AA was the ONLY hand that beat me BTW. Oh well...at least I can say they made a movie about my hand.
