For information about setup and rules:
http://www.talkchess.com/forums/1/message.html?329237
Looks strangely familiar? - yes, the controversial setup of game 2 again. Space
advantage vs. pawn - OK, nothing new, we get this in every other game.
This time after the "novelty" 27. Nf4 Junior reached less than nothing - it's
just too drawish.
In 1985 there was some upset in our little rural chessclub - a computer had
proven hat KRBKR was a forced win, amazing. Dunno how this came up, and of
course these days we know better - many if not most of these positions are a
draw.
But surely not all of them - KRBKR is dangerous to the extreme, especially if
the defending king is restricted to the back row - Crafty deals with these
positions as a draw statically in general (my humble and very possibly wrong
judgement after watching the game and evals , no analysis of source coude ) -
dary judgement by the engine.
Not to have to deal with general criticism about setup I spent quite some time
tonight with the best and fastest computer I could come up with in analysis - of
course with all the 5-piece tablebases, to make sure the problem is for real.
It is - Crafty is not aware that KRBKR is just mean, even with 5 piece
tablebases, something very similar (identical in fact) to the actual game would
have happened.
Game 6 featured 0.00 evals by Crafty for about 30 moves, until the huge
fail-low.
(all comments without any warranty at all of course)
Standing: Junior 2 - Crafty 1 ( 3 draws)
