Two leading chess programmers have joined forces. An unique new development in computer
chess. It surely will make both REBEL as CHESS-TIGER much stronger chess players. The
expectations are high.
The idea itself (to combine 17 and 16 years individual chess programming ideas) is
estimated to have a potential of at least 100-150 elo points progress. On this page
you can follow the developments.
CHESS-TIGER ideas to REBEL
- One of CHESS-TIGER's search algorithms has been implemented in REBEL and is further
improved by Ed Schröder. The CHESS-TIGER idea plus Ed's own improvements have speed up
REBEL with a factor of 2-3. The first results are very promising. At the playing level
of 1:00 per move REBEL scores 47½-31½ against various strong computer opponents.
For the moment the conclusion is Christophe's idea has given REBEL an elo jump of at least
30 elo points but more likely the gain in playing strength is 50 elo points or even
more. The basic idea is implemented in the third party engines of:
Please note the "REBEL10 engine for ECTOOL" is free for REBEL10 customers who have subscribed
so you can already have a look for yourself. More info on the

REBEL ideas to CHESS-TIGER
It will take some time to report the results and conclusions.
- As a result of Christophe's idea to Ed which has made REBEL 2-3 faster Christophe will
investigate if Ed's suggested improvements to the search algorithm will work for CHESS-TIGER
- Currently the King Safety software of REBEL10 is implemented in CHESS-TIGER.
