Hi Jon,

The game is from Morella,J vs Fernandez,E Cuba 1998.

Also, You may have not seen this thread from Bob, reporting the bug in Arasan which was originally posted in programming forum and moved back here.

Interesting, Dann. That Rybka 2 solved faster than the latest one on this, maybe it's worth reporting to Vas?

I doubt if it is very interesting. I guess that many problems with have similar outcomes. But if you take 1000 hard problems, probably Rybka 3 will solve 80% of them faster than Rybka 2 or so.
