Go up one level in this thread
In a german chess magazine the following game was published !
Claus Carstens is known as a guy who plays very SHORT games against
computers. Over the years he got many critics, because people said he
would construct his games or that nobody can replay the games and they
are not really played with the programs he says.
I have tried to replay the game he printed with my k5/100 and gave it
twice the time CC gave it.
Despite 1...d5 i was able to replay all moves. My junior played 7 times
or more 1...Nf6.
Lets say Junior really played this game the way carstens says, still we
don't know how often carstens took back one move, tried another line,
took back the move again and this way constructed a game until the end.
It is the problem with autoplayer-games. Even IF you can replay the
printed games, you don't see how (e.g.) the opening book (of machine A)
directed the programs into exactly the line, the opponent (program B)
would lose, because it has been played before on the autoplayer of the
company A and lost all other variations. And the game we see is the only
game that was won.
The same problem with Claus Carstens. He prints ONE game, but he maybe
not publishes the games he tried before to get this game work.
PLease : the annotation is from my k5/100, Carstens used a k6/200 .
I was able to replay all moves, despite 1...d5.

Blackmar-Diemer-Gambit is a tough opening for ANY chess program. I guess
you can kill almost any program with BDG.
But this example does not really show us the STRENGTH of Junior. But it
is a good example that TACTICS and TACTICS is not the same. The tactic
that occurs in a game, and the tactics a program SOLVES in a test-suite
is completely different.
I will later this day post some winning games of junior I like.
