to the Vonset L6-v1.
. I really can't find any reason for such a move; there is no deep calculation involved thus it can't be a horizon effect. I also couldn't figure out how a null move insertion could eventually raise a hope for the Vonset; therefore I suspect a hash collision. Once the game completed, I replayed it until the blunder position: at first try the Vonset played another, harmless move; but after a take back chose the same blunder again. Therefore the bad move is context-dependant rather than resulting from a clear programming error... And the game ends in no more than twenty moves. | Folgende 3 Benutzer sagen Danke zu Tibono für den nützlichen Beitrag: | ||

Good evening,
last match for group 6 is CXG Super Enterprise vs Mephisto Berlin. That's close to 500 CElo gap, so no-one should be surprised by the outcome: two indisputable wins for the Berlin. No epic combination to point out in those games, only the usual slow pace and step by step strangulation from the Lang protégé.

Good morning all,
the first game for group 7 is just a formality for the mighty Mephisto Chess Challenger tuned to 32Mhz, facing the Mephisto II "brikett". In the first game as White, the brikett leaves its King exposed in the center for a bit too long, gets aware castling became urgent but chose the wrong side  : castle long while the a file was already semi-opened for the ennemy Rook. I think this was the main mistake committed.In the second game, the Mephisto/Saitek Chess Challenger playing with light pieces achieves a strong domination of the center, thus the Mephisto II couldn't do much.

Hi,
next game is an opportunity for me to get the Conic Computer Chess out, as I didn't use it since long. Well, I think I remember why, now... The issue is not with the playing level; sure it is weak, but I play with a lot of tenderness with any weak chess computer. No, the flaw is this metal jacks system for move detection... Moving the pieces on behalf of the Conic is not an issue, as long as you reach the expected position the computer is happy. The other way around, which is inputing your player moves, is another story. The device is very sensitive to the way you manipulate the pieces, and is prone to reject your move tentative, displaying blinking LEDs instead of steady ones. And this can happen at any step: when pulling your piece out of the source square, when pulling an ennemy captured piece out, when inserting your piece down in the target square. If so, you need to restore the initial position and retry the move from scratch. Sometimes it can fail several times in a row... thus move, move back, move, move back, retry... The worst case is castling. You need to successfully pull your King and get a steady LED. Then insert the King in its new square, woops, blinking LEDs. Set the King back in initial place. Pull the King. Blinking LED, not good. Re-insert the King. Pull it, by chance the LED is steady, insert it in the new square, great !! Second steady LED! Now pull the Rook out... Sh*t, three blinking LEDs... restart from scratch  . Long story made short, you need a bit of luck to achieve the castling move with four steady LEDs, now you can press Enter to let the computer move.Well, after playing a couple of games, you should have developed some training and technics increasing the chances for successful move detection: be straight and fast, but not too fast; let the piece fall freely in the location then apply a clean vertical fast push down from above, if this doesn't work insert only a couple millimeters, make sure the LED is steady, and once this occurs, complete the push down of the piece...  The good news is, despite the hassle, one can play full games assuming a bit of patience. And games were not that long, as the opponent is this round is the Fidelity Electronics Excellence (3 Mhz). 600 CElo points difference is more than enough to shorten the games to around twenty moves  ...

Good morning,
next match is a no-brainer for the standard Mephisto/Saitek Chess Challenger, thus running at 10 Mhz: the Boris Diplomat is pretty helpful, aiming at soon encountering better suiting chess computers for itself. Zero points should be convenient for a better fit, next round.

Hello,
let's complete the first round of group 7 with another definitely unbalanced game: Saitek "Kasparov" Blitz vs Fidelity Chess Challenger 10, again more than 600 CElo points discrepancy. In both games, the CC10 soon suffers a material disadvantage, and that's enough for a fast collapse.

AW: The 64-cup
Good afternoon everybody,
round 2 offers an opportunity to Mephisto II "brikett" to start scoring, as it has to play with the Conic Computer Chess: with close to 250 CElo points more, the brikett should at least score 1.5 points. Actually it achieves the full 2 points, but it wasn't that easy: playing with black pieces in the first game, the brikett couldn't get any substantial advantage during around 30 moves; even suffering from a bad position in its King's corner. Fortunately for the Brikett, the Conic failed to a fork from a naughty Pawn, which will toggle the game in favor of the Mephi II. In the second game, the brikett playing as White gets out of the opening phase with a strong center domination; both devices castle long, the game opens and the Mephisto II center Pawns apply pressure - one of them will later promote.

Hello,
odds for next game are 2/3 to 1/3 in favor of the Chess Challenger 10 facing the Boris Diplomat: both devices date from the same era, and the match is fair. Maybe I forgot to tell this CC10 is the "B" version, as aware ones would have noticed thanks to the castling moves. The Boris Diplomat keeps up in the first game until move number 11 (playing as Black) but stupidly loses a Rook and of course, from this loss on, just goes down. Funny enough, next game playing as White, the Boris commits a mistake on move number 11 again, and the Chess Challenger 10 dominates the rest of the game. It ends in a draw though, as no code prevents position repetition; this is how even the weakest chess computers can score when playing other weak computers.

AW: The 64-cup
good evening all,
now something I much appreciate from such a competition... a big surprise!  This happened in the match Fidelity Excellence vs Mephisto/Saitek Chess Challenger 32 Mhz. According to the (my!) relative rankings, the Excellence can dream of stealing one point from the very fast Morsch program once in 9 games... And did it!  It was the first game, Excellence playing as White. I don't think the MCC32 committed obvious mistakes, by the way no H8 bug occurred (this could have been a reason for a win by the Excellence, but...  ). Rather the Excellence played a very strong move 22; with a lot of potential consequences, if my analysis is correct (it was a tough one). I think it has been the game changer move, but the Excellence had still 50 or so more moves to play to achieve the win, not an easy challenge facing the... Challenger Well, I struggled and lost so often playing the Excellence that I am happy seing such a strong computer as the MCC32 can be on the loser side as well Of course the Chess Challenger 32 Mhz got a clear revenge, playing as White in the second game.
