I'll start it off.
I gain most of my profit from SnG's. I play very tight and aggressive, double up when I hit a strong hand, and wait for the others to knock eachother out before I start playing crazy. My success rate in SnG's is placing in 8/10.
I also do quite well in MTT's, but I haven't been able to hit a large payout yet. I place in 6/10 that I play in, but I haven't made anything substansial from them yet. Hopefully soon I will hit one, but until then i'll keep playing in them and gaining experience and padding my pockets little by little.
Right now, I lose most of my money at ring games, and I am staying away from them for the time being. I play tight aggressive at ring games just the same as I would in a SnG or a MTT, but I always get stupid donk callers that river my AA out with a weak flush or low straight. I haven't been able to control my gains/losses at ring games the way that I like to, and I will keep playing SnG's until I get to the point where I can play rings at a higher limit so that I can hopefully avoid donk plays.
