Go up one level in this thread


It seems odd, but this is very logical. Several years ago, I wrote a *very*
basic chess program (4 ply full width, no extensions, no pruning. basic opening
book, and could only mate with Q or 2R, very primitive evaluation function
[basically material count, with a few bonuses and penalties thrown in]) that
should have played like crap. I played it (I'm about USCF 2200), and I thought
it did, but played it as a guest on the old ICS (before it went commercial), and
came up with a 40 game performance rating of about 1500 in blitz.

It beat a *bunch* of 1200-1400 rated players, simply because they hung pieces
outright, and FUBAR (my program) never did. It came up with simple 2 movers to
win material. Many players resigned against it before they should have.

I actually studied several hundred blitz games from players rated 500 to 2000
ICS blitz, as I was teaching chess to several students, and a couple schools
back then. The chief error that players rated 1300 and below made was simple
tactical blundering (hanging material outright, or within 4 ply). Even the
*simplest* program will take advantage of this. I focused on this with my
students who were rated below 1300 USCF. If you can avoid the dropping of
material outright, it seems that you pick up 100-200 points in strength imm
ediately.

Actually, programs like this are a great benchmark. Once you start beating them
(which you will), you know that you've been addressing the tactical problems,
and are making progress.
