Same 30 engines, now using 2-moves.epd, only 404 positions.
#1. Look at Gideon from 1993, 5th place before SF10. A time before the internet, null-move was not invented, neither reductions, neither futility pruning etc. A time when a ply was a ply and you could count the number of moves of a combination and calculate the iteration an engine had to find the right move. A time also that all the pruning and reductions did not affect the evaluation function in a negative way.
#2. The once almighty Rybka at the bottom.
Next: 3-moves.epd (1221 positions) now running.
Your system of adding points is completely bogus, sorry.
I have downloaded your 2moves epd and already the first two positions show
that you have not thought much about it, or were too biased.
[d]r1bqkb1r/pppppppp/2n2n2/8/2PP4/8/PP2PPPP/RNBQKBNR w KQkq
Code: Select all
r1bqkb1r/pppppppp/2n2n2/8/2PP4/8/PP2PPPP/RNBQKBNR w KQkq - c0 "Nc3=53, Nf3=46";
3. d5 / 3.g3 are surely as good - still 0 points? What about 3. Bg5? /3. Bf4?
[d]r1bqkbnr/pp1ppppp/2n5/2p5/2P5/2N5/PP1PPPPP/R1BQKBNR w KQkq
Code: Select all
r1bqkbnr/pp1ppppp/2n5/2p5/2P5/2N5/PP1PPPPP/R1BQKBNR w KQkq - c0 "Nf3=100";
again 3. g3 and 3. e4 are as good - still 0 points
After those first two lines I stopped looking further.
It is impossible to create an opening test out of this in a few hours even for 2 moves epd, actually
it would need several days or weeks and a good player and an opening encyclopedia and the understanding
that in early stage there are often not best moves or only moves and it is just a matter of taste to chose
between good and equal moves.
It could be seen already from your first statement when you favoured 1.e4/1.d4 (10) over 1.c4/1.Nf3 (8) nothing
in chess nowadays suggests those are inferior. You just need to know how to continue or what setup to reach
and this is far beyond 4 moves of course.
All of this is an extreme case of being too simplistic.
