These players are my favorites for building my pot in the earlier stages of a tournament. You have to play very tight around them and wait for the nuts....and as blueskies says, position is very important... really....I'ts very, VERY, very important, especially when playing with the agressive/maniac types... and its pretty important the rest of the time. When theres a maniac at my table, i shift into low gear, I play as tight as I know how to, and have been known to fold even AA, KK without even betting if I'm not in the right position (late to on the button)... I be folding alot of hands, but when I finally get the nuts..AA, KK, AKs maybe AQs or off suit... (depending on your comfort level) I play like im scared and like Ducky7 said, I let them do the work... and just follow em down to the river like a stupid little donk, then I push and I rarely fails... I end up with all the chips they had been busy stealing...lol
of course, there are alot of variables there.. like your in position and bully leads out with mega bet and you limp behing and the flop brings something like Aks 7o...or what ever.. if its a scarry flop and I have the nuts.... I push the player all in and that works better than giving them the chance to make a hand down one of the next streets... sometimes they fold, sometimes they don't thinking they can scare me off by raising.. but once Im committed, that aint happening and I can asuure you, I've won way more chips this way, than I have lost... Once you have the nuts... own them and kick the idiots butt... show em how to play... and...if you loose anyway... then know you ain't no sissy and you went out like a champ... not with 23o in your hand! Good luck!
