I have a real hard time believing that the two limits play that much differently yet my results are DRASTICALLY different. Yes, I did run poorly over a short sample at 25NL earlier this month as well this past weekend but I think there is a bigger problem going on.
The mental wall.
To put it more eloquently (or perhaps less, dependent on your view), I mind-fuck myself whenever I play the higher limit which is quite sad. Its 25NL! A whopping $25 buy-in. Yet somehow, tt gets me off my A game; I end up doubting the plays that I am making. The only cure I can think of is to just keep throwing myself at it until I break the wall down.
So I'll keep on paying for my shots by 5tabling 10NL and having one table of 25NL up and running.
Any other ideas/suggestions are gladly accepted.
