I do this OTB at the moment.
Currently only one person I can play with who is around my level.
I am slightly better, so sometimes I 'miss' killing tactics to keep the game interesting.
If I win every game, then we both lose an opponent, and there is plenty of other value to be gained from OTB games.
There's a guy in my club whose results are bizzarly unpredictable. 2 weeks ago, he beats 3 1800s. Then last week, he loses to 2 1500s and a 1300!
From uscf stats, over the last year he's gone 5-13 againts 1900 players, 16-30 against 1800 players, 20-24 against 1700 players, 8-11 against 1600 players, 4-8 against 1500 players, and 5-3 against 1400 players! (im not counting draws) All while having a rating that fluctuated between 1700 and 1900. What could be the reason for this? Do you expereince this "playing down" effect yourself?
