Hi

Rapid Chess tournaments 
Round Robin 
Time control
20 minutes + 10 sec. on Athlon 2600+
This tournaments will start on Sunday, April 4th and the Pyramid will be paused for a while. 
Despite of already a lot of good tournaments with longer time controls like WBEC, RWBC, WCCL, Chess War etc., I have decided that I want to add also a bit in this respect and with Nunn positions, as Blitz games were criticized a lot. I am also interested in a comparison between Blitz and Rapid Chess.
Anyway I will also continue the Blitz tournaments, because they give a lot of games (so rapid chess over the day and Blitz tournaments overnight). All done on three computers, crosstables will be updated all two days at my site. 
Starting with Nunn position 1 and hopefully proceeding to position 20 with more tournaments to come after each cycle worst four engines from leagues A, B and C will have to go down and best four from B and C will promote. In case of equal score a shootout will be done.
Updates are allowed after each position is completed.
The Leagues are corresponding to my rating list with a few exceptions. All who might argue that they belong to a higher league...promotion can be achieved quickly...If I forgot anyone, please let me know.
