Sam has closed his piano and gone to bed ... now we can talk about the real stuff of life ... love, liberty and games such as Janus, Capablanca Random, Embassy Chess & the odd mention of other 10x8 variants is welcome too
For posting: - invitations to games (you can also use the New Game menu or for particular games: Janus; Capablanca Random; or Embassy) - information about upcoming tournaments - disussion of games (please limit this to completed games or discussion on how a game has arrived at a certain position ... speculation on who has an advantage or the benefits of potential moves is not permitted while that particular game is in progress) - links to interesting related sites (non-promotional)

Now that I have the database code working (I still need to verify my latest computation) it appears that the longest win is a mate in 40 moves. In 8x8 chess, the longest win is 33 moves.
OK, the contest for guessing the longest win can officially start. Post your guess here. The person who submits the position resulting in the longest number of moves for white to win will receive a stainless steel Gothic Chess mug for the price of shipping.
And here are some stats of the latest run, assuming everything verifies properly when I do the test tomorrow:

Hey! Hey! Hey! No fair giving away the answer to Fencer! If you guys wanna turn some shady deals, you'd better do it behind closed interfaces or whatever, 'cause it makes the rest of us jealous. /Fx/
I am a little confused ... well, a lot actually. Are we to post here our proposed starting positions or are you going to set up one of the 245 40-move alternatives for us to solve by playing you? If we are to post here then I guess we should also post the solution which may have a number ways of getting there.
