sometimes i min. bet (if i'm chasing) too keep the one who really has a good hand from betting bigger. he thinks he's trapping me, and when i do catch up it's too late for him to realize his mistake. always remember people's bets even from hands before. um... use pt3. take notes, lots of notes. those rag lovers be careful of best in a sng to leave the table and find a new one, because they are extremely unpredictable, or wait till you have a monster hand. (notice micro sng's really doesn't seem like texas hold'em, but more like texas chase'em). here's another tip for exploiting another's betting pattern.
seem loose, but play tight. this might sound bad, but if you notice someone betting maniac, then feed him chips, call. call. fold (even re-raise when he calls and raises the next hand fold). (hehe micro table only). set him up a few hands, and let him feel like he can bully you all the time, and be extremely patient. then trap him, (throw in a re-raise so he calls) then knock his teeth out for the lost chips wit interest. (other people may also feel you can be bullied too seem weak, be strong. people don't remember that poker isn't just the cards in your hand, but like chess it's always good to set people up for later hands. ex. showing a bluff, then raising the same amount wit the nuts.
good luck i hope i helped.
