I never minded losing to good players. It's the losing to complete idiots that sends me over the edge. When I found myself being pissed off at work the next day after a frustrating night of poker, I knew I had to do something.
How many tables are you playing at 2/4?
I play 4 tables with no overlap. I've tried adding more, but I like to pay at least a little bit of attention to what the other players are doing. I'm winning 3.03 BB/100 over 24,000 hands so I guess I'm doing something right. Of course GT+ helps a lot.
When I first went back to 10-handed I had to make some adjustments in a hurry. My vpip was through the roof and I was pushing 2nd pair and top pair/weak kicker like I had the nuts and I got burned.
I could move to 3/6 but one of the things I like about 2/4 vs. 3/6 is that the players at 2/4 are much easier to manipulate. They check to the raiser too much and they love to slow play. You see more aggression, stop and go's and bluff raising at the higher levels. Right now, all I want to do is clear $500 per week in bonuses with as little stress as possible and if I make a few bucks on top of that, all the better.
