No problem. It's just that I have been working very hard these past weeks, so I
was a little bit irritated by the "no excuse" comment. :)
I should take some rest now. I'm getting a little bit unpleasant. :)
Sorry.

I have fixed a number of such problems in the endgame by adding specific
knowledge.
I like the idea that my program can play the endgame on its own without relying
on 2Gb+ databases clobbering the hard disk.
Anyway, when I implement TBs, it will bring a nice 20-30 elo improvements. Given
that most of my opponents have already TBs, that means that I'm going to steal
this amount of elo points from them and they will not get them back. :)
