I have been playing correspondence chess since the 1980s,  I still play OTB at my club and at weekend tournaments, preferring the normal, full length games.

Like most people my age (75), my ability in bullet, blitz, rapidplay etc has deteriorated.  I am finding it hard to calculate at speed, and even physically making the moves on a computer can be frustratingly slow.  So please do not be offended if I decline to play live games !
