It used to be that they would come in for a raise with "Doyle", 10-2 off. Yesterday at the Bellagio in 15/30 limit I twice saw people call 3 bets out of the blind with Q7. If a starting hand has a "name" they are getting in there it seems!
Yeah, it helps if you can identify players who play these "named hands", it helps you identify them as loose and or maniacs. Probably should play looser and more aggressively against them if they are calling that kind of garbage to 3 bets.
