Crafty 19.4 - Junior 8.0.0.2
[D]3rr1k1/bpp2pp1/p1n1bn1p/3qp3/PP6/2PP1NNP/2B2PP1/R1BQR1K1 b - a3 0 1
The position that finally decided this very close match. In this quiet and
completely equal Guico line, Junior in suicide mode trapped its own queen in the
middle of the board with the amazing 16. ...Nd7?? .
After the obvious 17. Ne4 it had to do serious harm to the position to let it
escape. Although Junior did its very best to put up a tough fight afterwards,
resistance was more or less futile.
So, the winner of this experimental match is: Crafty.
But it was a close result, much closer than most readers would have expected I
assume.
The brilliancy price would go to Junior that played some truely amazing games
IMHO. Most games saw Junior sacrifying one or two pawns for position, and it
seems to have a very good understanding of compensation, especially when it is
about space <-> material.
I often found myself cheering for it, it's just fun to watch its unique
approach.
To go back to the discussion that started this: it looks as if Crafty on 10
times faster hardware is indeed very competitive with a top commercial engine,
but not necessarily the overwhelming favourite.
Of course it was just a single match, and I don't claim any statistical
significance at all.
Hope some readers were interested in reading about this match anyway, and had
some fun.
I wish you a happy Christmas time!
