October 2000 Rebel Century 3.0 second on the ChessBits rating list
ChessBits is an independent bi-monthly computer chess magazine in German. On the latest ChessBits rating list Rebel Century 3.0 is listed no.2.
ChessBits about Rebel Century 3.0:
The first results indicates that Century 3.0 is 157 elo points better than its precursor Century 1.0.
Unfortunately the auto232 driver prevents Century 3.0 to have a better ranking. When one only counts the games played by hand than the new Century 3.0 would be ranked first miles away from the competition.
More about Rebel Century
Rebel Century 1.0 during the 1999-2000 season together with 3 other chess programs (Fritz, Junior and Shredder) participated in the Israeli League. Rebel in total played 8 games against strong human players on normal (tournament) time control. Again Rebel proofed in its natural style and class playing strong humans. Rebel Century scored 5½ points out of 8 games losing only one game (W4 D3 L1). Rebel Century scored a TPR of 2541 and with this result Rebel (again) was the highest rated computer. More.
Rebel Century 1.2 during 1999-2000 played several games on tournament time control (considered as the last straw of human kind) against strong grandmasters with as highlight the game against Vassily Smyslov former world champion. More.
The chess press about the Israeli League:
Selective Search: The REBEL CENTURY result and rating is a big boost for the programming effort in concentrate on its v human strength.
ChessBits: You can evade the question as much as you want but REBEL since years and at every opportunity proofs itself to be the strongest around against humans with a continuation that is astounding.
Rochade Europa: Very successful in the Israel League was REBEL CENTURY from Ed Schroder. This dutch Program for years has the image to play particular effective against strong human chess players. REBEL again proofed its image to be true, REBEL CENTURY scored 5½ out of 8 rounds, being the best computer chess program.
October 2000 Rebel Century 3.0 wins the strong DEBRECEN tournament
Pictures from the tournament.
Rebel Century 3.0 wins the yearly DEBRECEN tournament in a convincing way 1.5 points above the second best computer.
The traditional Debrecen tournament in Hungary from its origin was a normal human chess tournament. Later computers were allowed to participate but when computers started to dominate the final ranking the Advanced Player was introduced.
An advanced player is a strong human chess player who with the help of a computer chess program of his choice is playing the games. And with success as the final ranking is indicating.

December 2000 Jeroen's Christmas 2000 tournament
Specifics
. Hardware: 2 x K6-II 500 MHz.
. Time control: 90 minutes for the whole game.
. Manual games (no autoplayer)
. Seven rounds robin.
Jeroen Noomen over the last round: "A sensational last round led to a double victory of Tiger and Century! First Tiger had to deal with Gandalf. It was no match at all: Tiger stood better after the opening and Gandalf had a lost position after less than 30 moves.
That left Century the big task to beat Fritz as Black. After a Sicilian Fritz sacrificed the exchange and thought the position was equal. Century believed in a clear advantage. The ending became dramatic: Century's evaluation dropped, but..... Fritz got nullmove problems!!!! It still showed 0,00 when Century already had seen the win. Suddenly Fritz's evaluation went to -2, then it was too late.....
Wow, what a game and what a nice conclusion to this tournament!

Specifics
. Hardware: 2 x K6-II 500 MHz.
. Time control: 5 minutes for the whole game.
. Manual games (no autoplayer)
. 4 games per match.
Jeroen Noomen over the last round: Thanks to a 4-0 whitewash against Gandalf, Tiger 13.0 managed to win my blitz tournament in the last round. Fritz 6a became 2nd, thanks to a VERY LUCKY 2-2 against Century 3.0. Yes Ed, it should have been 2,5-1,5 for Century, but a tablebase draw spoilt a winning position....

REMARKABLE: Rebel Century 3.0 during the whole tournament was leading and only needed 1 point
in the last round to win the tournament or just one draw to end first together with Tigert II.
But then its opponent in the last round was Rebel-Tiger II (engine Chess Tiger 13.0) and
Century 3.0 lost both games! and so it was the TIGER again winning another tournament. Not that
it matters as the victory remains in the REBEL family after all BUT who can stop the
Tiger? as it seems to win almost every serious tournament.

Conclusive by Heinz-Josef Schumacher: The progress of the "New Generation" of chess programs is in close bounds and only a few updates are really worth the money. In this respect only the REBEL 11 package with Tiger 13 and Century 3 convinced me, more it offers the best price what you can get for money.
January 2001 Match REBEL-CENTURY 3 versus GM John v/d Wiel 3½-2½
After the matches against Arthur Yussupov and Vishy Anand which were mainly about short time control Rebel in January 2001 had to face a new challenge. This time Rebel had to compete against the world best computer fighter AND in the area the human still is superior that is tournament time control.
Download all the games GM John der der Wiel has played against computers and notice his tremendous score of 24½ - 3½ against the silicon losing only one game in 1990 but that was during a simultaneous play John gave in Brussels so actually John never lost one single serious game against a computer. Outstanding and unrivalled!
But REBEL is a different animal, it has a playing style that is well suited to play humans and has been tuned for many years to compete in the human area, it has an anti-GM algorithm to avoid anti-computer strategies, it has a special time control when playing humans. All of this was responsible for 6 spectacular games, the human leading after the first 3 games with 2-1 but then the season turned and REBEL was without mercy and scored 2½-½ out of the last 3 games making the total of 3½-2½ in favor for REBEL!
GM John van der Wiel about his computer opponent after the match: It avoided 'anti-computer' type of positions more often than other programs so far. Still it made quite a few mistakes (I have to add that I certainly made more!) and in the middle-game treatment there is a lot to be improved. I was impressed by REBEL's endgame technique, though. Looking back at the match I am convinced that a Van der Wiel "in form" should definitely come out victorious.
