Okay, I've finally managed to run my CC gameload down to 10 games, in order to get the energy for concentrating on my horrible blitz. So today I fired up ICC and played about 20 or so 5-minute games. First I went down to 1180, then back to 1320, and after I started getting tired I leveled around 1250. I haven't slept much, to it's an okay result. The games were nothing to write home about, I messed horribly all the time, dropped stuff, lost from being pieces ahead etc etc... The usual stuff. Surprisingly I didn't lost that many games for time.
The plan is to start (once again) playing at least some games daily, ignoring ratings and just hammer on until I stop doing those stupid brainless blunders my blitz is filled with. Just aim for a simple solid game, and especially playing those 'won' games like they should be played. Prevent counterplay, simplify and win. Get the basic game into shape.
