Hello!
Gothmog 0.4.5 for Windows, Mac OS X and Linux is now ready for download. The main
improvements are:

A terrible bug in the evaluation of passed pawns, backward pawns and isolated pawns
has been fixed. All previous versions of Gothmog (at least 0.3.0 and later) gave all such
pawns a bonus (in case of passed pawns on the 6th and 7th rank, a very big bonus) for
not being able to advance safely, which is of course precisely the opposite
of how it should work. Fixing this seems to have given a quantum leap in playing strength.

There was a less serious bug in the evaluation of positions where one side had only
the king left. The winning side was given a too small score in many positions.

Some new positional knowledge added.

Some blitz results for the new version:
Gothmog 0.4.5-Phalanx XXI: 52.5-47.5 (+46, -41, =13)
Gothmog 0.4.5-Arasan 7.2: 68.5-31.5 (+62, -25, =13)
Gothmog 0.4.5-SmarThink 0.17a: 7-13 (+6, -12, =2)
Gothmog 0.4.5-PostModernist 1007: 10.5-9.5 (+9, -8, =3)
Gothmog 0.4.5-AnMon 5.21: 12-8 (+9, -5, =6)
Gothmog 0.4.5-Dragon 4.5: 13-7 (+12, -6, =2)
Gothmog 0.4.5-Taktix 2.23e: 19.5-0.5 (+19, -0, =1)
I am particulary pleased about finally winning a long match against Phalanx, which
has been my main sparring partner and yardstick of progress ever since I started
working on Gothmog again during last spring. If I had known back then how much
work it would take before I could finally defeat Phalanx, I wouldn't even have bothered
to try.
