Subject: SSDF results and their relevance

There was some mention recently of SSDF results and their relevance to the real
world.

I reckon the work they do is very valuable but it cannot possibly be the
de-facto standard for ratings of chess computer programs as they only use one
time control.  So programs get better results at faster time controls, and
others at slower time controls.

IMHO the only true way to get a true reflection of a chess game's rating is to
play against humans at a variety of time controls.

However failing that a substantial number of games against recognised chess
computer competition at varying time controls would give a more accurate
comparison.

I do find that of the top programs some do manage sudden death time controls
better than others, surely this must be taken into account when assessing the
overall strength of the program?

After all, every move calculated by a chess computer in a match is a compromise
in time or we would never finish a game....:-))
