Hi all

I am announcing an event with longer time controls. The idea is taken and modified from the Correspondence Chess Organisation IECC, where I participated in the Pyramid Ladder for several years.
I recommend this fine site to anyone interested in email chess.
http://www.iecc-chess.org/
My own rules you find here:
http://www.husvankempen.de/nunn/conditions.htm
In the Pyramid each engine plays up to two games in a cycle, one as a challenger and one as a defender.
Challenged can be any other engine that is not more than ten places above in the ladder I set up from my current rating list (see http://www.husvankempen.de/nunn/ or below in this posting) , for example an engine ranked 41 can challenge those ranked 40, 39, 38 etc. up to 31. The challenger plays with white pieces and has to win in order to swap places with the defender. In case of a draw or win of the defender the Pyramid ladder remains unchanged.
The Pyramid changes frequently and an engine can gain more than ten ranks in one cycle. For example: Cerebro ranked 59 challenges DanChess on 49 and wins. In the same cycle Dan Chess challenges Leila ranked 39 and also is successful. New standings after the cycle will be 39.Cerebro, 49.DanChess, 59.Leila.
Engines that are not in the ladder so far, for example Drunken Master, Sharper, Alarm, Gullydeckel, Rinko, Deuterium etc. can anyway issue a challenge to those ranked 91-100 and possibly replace them by winning. Hope I did not forget anyone belonging to the Top 100, otherwise this will be corrected.
I will frequently update the list before each cycle starts, so that everyone can see, who is already challenging or defending.
Examples: Comet D38
Gothmog C31
This means Comet has been challenged by Gothmog ranked 38 and not issued a challenge so far. Gothmog has challenged Comet ranked 31, but is still available to be challenged according to the rules above.
Time controls and other conditions:
The match for the top seat is on tournament time control 40moves in 2hours.
It will be commented and probably there will be live coverage.
Games involving an engine ranked 1-50 are 40 moves in 20 minutes.
Others 40 moves in 10 minutes.
Hardware:
Athlon 2600+
128 MB Hash (for final 256 MB)
Fritz GUI
Nunn position (randomly chosen by drawing playing cards 1-20)
4 and 5 men EGTB
Ponder=false
I hope that I will be able perform one cycle each week. Testers who want to participate and add some more CPU time for matches, please contact me via email. You are of course free to use Winboard or Arena instead. Time control will be adapted in case of considerably slower or faster hardware.
All results will be posted regularly in Winboard Forum. The Pyramid ladder is updated after each cycle and then new challenges can be issued for the next cycle.
Please send all challenges to my email address: jaque64@aol.com Do not post challenges in Winboard Forum, as this would probably cause confusion or chaos. I will post a list of matches as soon as a certain number of challenges is issued. Authors may decide to participate with their strongest version, public or beta. Please give at least one opponent as alternative. Might happen that the preferred one has already got a challenge in the meantime.
First cycle starts as soon as there are enough matches, but not earlier than Saturday (February 14th).
Best Regards
Heinz
