I'll throw in some more words about FPS.
Last night, playing 4-handed, I was up against a guy who, two hands in a row, took pots away from me. I raised preflop, he called. I bet the flop, he called. One turn I check/folded once because I had zip, the other I bet and he minimum raised and I folded. The next pot we were in together, I checkraised him all-in on the turn with a missed AJ and he folded, and I got all my money back and more.
I got so pleased with myself that I proceeded to donk off more than a full stack at my other two tables, playing as if I could make anybody fold with big bets, properly timed. I got called down by one guy who had A8 on an 86653 3-flush board and by a different guy who had Q9 on a QJ3T3 board.
Oh, right, most players at $100 NL and below are calling stations.
I quit in disgust.
