Chess variants (10x8)

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)

题目: Re: Vortex vs. S.M.I.R.F.

rabbitoid: I think after 48 hours, the hardware difference is negligible. The branching factor is such that almost any machine will get you to the same nominal depth. Say with all of your pruning tricks your software branching factor is 4, down from about 50 in the actual game.

That means if ply X completes at time T, ply X+1 requires 4T, X+2 needs 16T, X+3 64T, etc.

If the speed differential was a factor of 4, meaning one machine was 4 times faster than the other, even after 2 days, the faster machine would only outsearch the other by 1 ply.

I am sure Reinhard's hardware is within a factor or 2 of mine, maybe even less. I have a 2.8 GHz Pentium IV.
