AW: The 64-cup
Hello, good afternoon all,
the Lexibook Chesslight somehow shares the unfortunate fate of the Sensory 6: as it earned 1.5 points in the first round, it has now the "privilege" to meet the seeded player, Fidelity Designer Mach III Master 2265. What did you expect? Two points granted to the Mach III, of course. In the first game, the Lexibook as White could not resist longer than move #6 before starting loosing ground. The second game was even shorter, even if the position was still approximately balanced until move #10.

AW: The 64-cup
Hi,
next match is an interesting one: Novag Super Nova vs Tandy 2150. With 72 CElo points in favor of the Novag, odds are 60/40 for the Kittinger program. As far as CPU performance is concerned, according to my estimate the 4 Mhz 6301Y of the Novag (16 Mhz with /4 divider) is close to, ~12% faster though, the 3 Mhz 65C02 of the Tandy. And the outcome is... 1.5 points granted to the Tandy! Despite playing the dark side, the Chess Champion 2150 played, to my humble opinion, a very good first game; positionally accurate and without obvious tactical flaws. If you check the position after move #16, you should see a strong center domination with a rather nice chain of Pawns, whilst the Super Nova has little to oppose. After move 38, the game is over for the Novag, still with that overwhelming center chain. Very impressive!  During the revenge game, the Super Nova dominated for a while, but the advantage faded away while reaching endgame. The prospects are then a drawn game, but the Tandy blundered on move 63 - a really bad tactical flaw - and the game was immediately a promised win for the Super Nova, with a Knight plus a Pawn advantage. Unfortunately it faced a dilemna: either sacrifice its Knight or its Pawn - and understandably but so wrongly chose to save the Knight, losing any chance for victory.

AW: The 64-cup
Good morning,
round 3 / group 8 starts with Fidelity Sensory Chess Challenger 6 vs Applied Concept Boris. In the first game as White, the Sensory 6 teaches Boris what a King attack is. The second game is a hastle: both devices perform a series of senseless moves, awaiting for something to change from the other device, each staying within its own half-zone of the board. The Sensory 6 is somewhat in a better position, but only a blunder from Boris will enable a potential win. Unfortunately for the Fidelity device, no code prevents from position repetition, and Boris saves half a point. A game to be forgotten.

AW: The 64-cup
Good morning to all,
next match is rather balanced, with theoretical 38/62 odds, between the Yeno 301XL and the Lexibook Chesslight. Indeed each device wins "its" game playing as White, therefore a fair division of points, one each. The 301XL is nevertheless dominated during the first half game as White, but fortunately for the Yeno, the Chesslight blunders on move #42. The second game is sort of a condensed, accelerated, similar scenario: despite playing White, the Chesslight is slightly dominated until move #20 but leverages a mistake from the Yeno to reverse steam.

AW: The 64-cup
Hi,
next match revealed much interesting. Well, rather the second game... Saitek GK2000 meets Novag Super Nova, with odds close to 1.5 / 0.5 score. And this is exactly what happened! But wait... In the first game, the GK2000 playing White gets the Super Nova out of its book as early as move #2, but can't leverage any advantage from this as it finds itself as well immediately out of book. The game is kept balanced for twenty moves or so, before turning to the advantage of the Saitek device. I guess the revenge game will please, at least attract attention from, the PSH lovers.  Unlike the previous game, both devices make use of their respective opening books, with a clear advantage for the Super Nova able to play twice as many moves from the book. Later, on move #18 and on the basis of a balanced position, it played what looks like a typical PSH-driven move, sacrificying a Bishop to dismantle the ennemy King's pawns shelter.  There is no material compensation to this sacrifice, only positional: a Knight + Queen threat around the ennemy King. The GK2000 is able to keep initiative, and applies pressure for a while, but at some point the potential threat resulting from the dangerous coordination Knight + Queen reveals too much for the Morsch program. Unfortunately (for the nice game sake) the Super Nova runs for a clear material advantage (a Rook up!), but doing so it lost initiative and the GK2000 can repeat a checking sequence and save half a point.

AW: The 64-cup
Good afternoon,
last match from group 8 provides another unexpected result: Tandy 2150 gets a full point from the Fidelity Designer Mach III Master 2265! According to the 285 CElo gap, odds were roughly 84/16 in favor of the Mach III. Or one point out of six games for the Tandy; therefore scoring so out of two games is an achievement. After leaving one point to the Saitek GK2000, another loss from the seeded player of this group is more than bad luck - and surely some Elo points abandonned once the tournament is over.  In the first game, the Mach III playing as Black commits a positional inaccuracy that lets the CC2150 widely open the position with an overwhelming control of center files. Soon this translates in a large material advantage (Queen+Pawn vs Rook) for the Tandy. Nevertheless not an easy win, with 50+ moves still to play. In the second game, the CC2150 as Black happily plays fourteen moves from its book, whilst the Mach III only ten. The position is kept balanced until late middlegame, then the Mach III gets a Pawns majority on King side. CC2150 defense is not accurate enough, it has no chance in the King+Pawns endgame, the Mach III leveraging its small, nevertheless efficient, hash tables.

AW: The 64-cup
Hi,
we now have all the information available to unveil the next phase of the tournament! Let's start with the main competition, 1/8th final, featuring sixteen chess computers: Code:
1st of group 1 DGT Centaur (2919) 2nd of group 8 Saitek GK 2000 (2000) 2nd of group 2 Novag Constellation Expert (1916) 1st of group 7 Mephisto Chess Challenger 10Mhz (2032) 1st of group 3 Vonset / Femuey L6-v2 (2496) 2nd of group 6 Novag Emerald Classic (1982) 2nd of group 4 Mephisto Milano v2.00 (2008) 1st of group 5 CT800 1.42 (2291) 1st of group 8 Tandy 2150 (1759) 2nd of group 1 Systema Challenge (1802) 2nd of group 7 Mephisto Chess Challenger 32Mhz (2138) 1st of group 2 Millenium The King Performance (2527) 1st of group 6 Mephisto Berlin (2181) 2nd of group 3 Fidelity Champion Sensory Chess Challenger (1569) 2nd of group 5 Yeno 532XL (1840) 1st of group 4 Millenium Chess Genius Pro (2303) As you may read, no additional randomization is applied: matches were pre-designed, and ranking first in any selection group translates into an advantage, which is to initially face a second-ranked competitor. Winners of the selection phase can only meet on quarter-final phase; this of course does not exclude some second-ranked devices to access the next step. And the consolation cup list is as well completed, simply complying with the order the third-ranked computers were identified group after group: Code:
1 Novag Beluga (1701) 2 Mephisto Rebell 5 (1816) 3 Saitek Turbo King II (1888) 4 Tiger Grenadier (1855) 5 Mephisto Maestro Travel (1561) 6 CXG Super Enterprise (1684) 7 Mephisto II (1426) 8 Fidelity Designer Mach III Master 2265 (2044) Other computers can take a nap... I shall start matches with the main cup: let's keep the consolation cup for later. In this elimination phase, computers will face each other an even number of times, with alternate colors, until we get a winner. If a match is still drawn after six games, the tournament director may change the level set in both computers (usually for faster games). No tie-break applies. Last rule, but not least: I am the tournament director  (and the referee as well  ).MfG, Tibono Geändert von Tibono (17.11.2023 um 14:43 Uhr) Grund: better list alignment

AW: The 64-cup
Good morning,
First match from 1/8th final is DGT Centaur vs Saitek GK 2000. Playing Black in the first game, the GK 2000 cannot stand a foot on the ground; and playing the White side, only resists twenty moves or so. 2-0 for the mighty Centaur, first chess computer qualified for quarter-final.
