Subject: King 3.23 among the top-4 engines

Recently it has been critized that SSDF doesn't test King 3.23 (yet), it has
been discussed, explained why not, etc.etc.

(Purists of 40/2h shouldn't continue to read :-))

I think nowadays, 10m+10s can provide a perfectly valid comparison too. On this
rating list created by Mr. Klaus Wlotzka for CSS Magazine,

http://www.computerschach.de/rangliste/

(For the details of the test conditions, click "Testbedingungen" in the menu.)

You can see King 3.23 has achieved rank #4 just behind Fritz, Shredder and
Tiger. King is running with Sel. 12 there (and 128 MB hash, rest default), so I
guess it could do a few points better with additional setting changes, i.e.
higher king safety. OTOH, I doubt that King could jump to rank #3 by that, which
is 17 Elo away. 17 Elo is a big distance nowadays in top computer chess.

King 3.23 is 71 (!) points ahead of current #5, List 5.04!

Let's not argue about 2 points more or less on the top :-)

(Junior 8 is the next to appear in the list; who can guess it's ranking?)

That rating list is based on 20-game-matches using a set of 10 very short
opening variants, with a total of 400 games of each engine.

You'll notice that the main list includes only one recent version of an engine,
each (unlike SSDF). But there's an "ewige Rangliste" too, see menu, which
includes all matches played so far to allow easy performance comparison with the
predecessor.

Very interesting is too, when you click "Übersicht" (=overview) in the menu,
where a comparison with the performance in 2m+2s blitz is given, using arrows.
For example, here you can quickly see that Hiarcs 8 was much better in that
short blitz (more than 50 Elo), while Shredder 7, Tiger 15 and List 5.04 were
better on the medium time control (20...50 Elo).
