Gothmog 0.4.2, and an incredible SmarThink result

I have now released the Windows version of 0.4.2. The Linux version will be ready for download
tomorrow. The Mac OS version is unfortunately lagging behind at the moment, even though
that is the platform where I do almost all the development. The problem is that my opening
book builder is broken at the moment, and I have no opening book in the new 0.4.x format
for Mac OS. I hope to fix this soon.
The main changes compared to 0.4.1:

More aggressive forward pruning and depth reductions in the search. As a result the
engine is considerably faster than before in most positions. The downside is that a few tactical
shots are found one or two plies later, but I still this is an improvement.

Numerous small bug fixes and tuned parameters in the evaluation function.

Improved CCT compliancy. In particular, Gothmog now kibitzes PVs in short algebraic
notation when playing against computer opponents in ICS mode.


The last few weeks I haven't had much time for development. The plus side of this is that
I have been able to run unusually many test games with the new version. Here are some
match results (at 4 minutes/game, with 2 seconds increment) for Gothmog 0.4.2:
Gothmog - SmarThink 0.17a: 19-81!
Gothmog - AnMon 5.21: 40.5-55.5
Gothmog - SOS 3: 44-56
Gothmog - PostModernist 1007: 45-55
Gothmog - Phalanx XXII: 49.5-50.5
Gothmog - Arasan 7.3: 56-44
Gothmog - Djinn 815: 63-37
Gothmog - Taktix 2.23e: 88-12
The result of SmarThink (my favorite chess engine at the moment) is extremely impressive.
The games in the Gothmog-SmarThink match were complicated and interesting. Gothmog
often managed to get advantageous positions, but was rarely able to win them. SmarThink
was almost always able to come out on top after the complications, and handled all sorts of
positions remarkably well. It was also the only engine which never seemed to overlook even
a single tactical shot by Gothmog. A fantastic engine, IMHO.

You're right -- I made a typo. The match ended 40.5-59.5.
