FairyMax - Glaurung

[hgm]

For testing the new XBoard tournament function, I had just picked four engines that were readily available for Linux (2 WB, 2 UCI): Fairy-Max, Crafty, Fruit and Glaurung. Nice to have Fairy-Max between these giants, because it loses very quickly. (This makes it a good test for the option that syncs all XBoard instances working on the tourney at the end of the round.) Or does it, really? In one of the games I couldn't believe my eyes:

Now this was playing two games in parallel on a single-core machine, (1.3GHz Celeron-M, so effectively hyper-bullet), so I cannot guarantee that both engines got equal CPU time. But the depth reached by Glaurung does not look suspicious anywhere, and is consistently higher than that of Fairy-Max. So no reason to suspect foul play here.

I guess this one will go on the wall! (Framed! )
