It's amazing how much you game can be off after just a couple of weeks away from. Several years ago when I was still rated around 1400 I worked with a kid that was 18 and we got to be sort of friends and discovered we both liked to play chess so we started playing together. I'll bet I must have played that kid a hundred games and never won a game, although I got close many times. My end game was just not strong enough to beat him. He was really good. He told me later that when he was 16 he was the top ranked player for his age class in the state of Texas. I guess that made me feel a little better. If I was to play that kid now he would beat me like I stole something.
