Default SOS 4 vs. Crafty 19.10 SE (CCT Champion) SOS don't know how to mate crafty with rook and knight!

First of all sorry for my English.

The game was played in Arena with ponder off and no egtb (because one
of my HD crashed last night).

SOS 4 got a final K+R+N vs. K and didn't know how to mate Crafty. It
is true that finally Crafty is mated but it seems that it was an
ocasional mate:

Default SOS 4 vs. Crafty 19.10 SE (CCT Champion) SOS don't know how tomate crafty with rook and knight!

The same for mine...

More than this, I'm a patzer, but I think I can help you on this (this
question is more apropriate for rec.games.chess.analysis or
rec.games.chess.misc)...

SOS 4 got a final K+R+N vs. K and didn't know how to mate Crafty. It
is true that finally Crafty is mated but it seems that it was an
ocasional mate:


The position you got after move 80...Kb5.
8/8/8/1k1N4/8/2R5/7K/8 w - - 0 81

From this moment on, the idea is to move the white king in the
direction of the rook to protect it, and give mate at the a-file. The
rook has the task of maintain the black king in the more limited area
that is possible. I used the knigth only to support the first rook
moves, and then I didn't used it at all. If you ignores the knight, it's
old theory, "KR vs K" (look at google for "elementary endings king
rook"). Here you have a link: http://chess.about.com/library/ble27end.htm

I put winboard in "two machines" mode, and this was one of the solutions
that arouse (I think that a change in time controle will give a more
refined solution, but I'm not sure):

[Event "Computer chess game"]
[Site "My Computer"]
[Date "2004.02.04"]
[Round "-"]
[White "GNU Chess v5.02+"]
[Black "GNU Chess v5.02+"]
[Result "1-0"]
[TimeControl "40/300"]
[FEN "8/8/8/1k1N4/8/2R5/7K/8 w - - 0 1"]
[SetUp "1"]

1. Kg3 Ka6 2. Rc5 Kb7 3. Kf4 Ka7 4. Ke5 Kb8 5. Kd6 Kb7 6. Rc7+ Kb8 7. Kc6
Ka8 8. Nb6+ Kb8 9. Rb7#
{computer wins as white} 1-0

I prefered another line:

[Event "Computer chess game"]

[Black "GNU Chess v5.02+"]
[Result "1-0"]
[TimeControl "40/300"]
[FEN "8/8/8/1k1N4/8/2R5/7K/8 w - - 0 1"]

1. Kg3 Ka6 2. Rb3 Ka5 3. Rb6 Ka4 4. Kf3 Ka5 5. Ke3 Ka4 6. Kd3 Ka3 7. Rb4
Ka2 8. Kc2 Ka3 9. Rc4 Ka2 10. Ra4#
{computer loses as black} 1-0

OK, the computer find a mate solution in 9 moves, and I in 10. Big deal.

How does black must play? In an KR vs K ending, the side that hasn't a
rook must try to stay at the center of the board, or to capture the
rook. So the white king has to go in the direction of the fight to
protect and cover the rook, and the two pieces must try to force the
black king against an edge of the board, and mate it there.

Usual mating patterns that arose (in all these positions black is mated,
look the important role that the white king has in this positions):
8/8/8/8/R7/8/2K5/k7 b - - 0 1
R7/8/8/8/k1K5/8/8/8 b - - 0 1
k6R/8/K7/8/8/8/8/8 b - - 0 1
k6R/8/1K6/8/8/8/8/8 b - - 0 1

You must take care that you do not stalemate black (the ending is lost
for black, but you always can blunder and give black a stalemate), as in:
k7/1R6/K7/8/8/8/8/8 b - - 0 1
k7/1R6/2K5/8/8/8/8/8 b - - 0 1
k7/1RK5/8/8/8/8/8/8 b - - 0 1

If you think you learned the principles, try finding the shortest mate
solution for this positions:

1R5K/8/8/8/8/8/8/k7 w - - 0 1
7K/8/8/8/3k4/8/8/7R w - - 0 1
R6K/8/8/4k3/8/8/8/8 w - - 0 1
7K/7R/8/3k4/8/8/8/8 w - - 0 1
6KR/8/8/8/8/8/8/k7 w - - 0 1

In the case of the game you pointed, if you manage to loose the rook
(big blunder, it's preferred to loose the knight than the rook, but it's
more preferred than that to give mate without loosing any piece - you
don't need to play sacrifices), it's a draw (KN vs K is a draw, there's
not enought material to mate).

Do you have a book on chess?

Obviously, my English is very bad. I know perfectly how to mate with
with rook+knight (even with N+B, I hope), but I was surprised of SOS
(a very good engine) making stupid moves not going directly for the
mate.

I just have wrote this because it seems a bug (or a weak point) in
SOS.

Maybe I need to go back to school... I'm sorry for that.

It was ugly. Apparently the program tried to get the distant opposition,
or something, in a position where it can get to mate the other program
in 9 moves.

Did SOS had any special configuration? And endgame tablebases?
