'''Ed Schröder''', (Ed Schroder)<br/>
a Dutch computer chess programmer and founder of '''Schröder BV''' <ref>[http://www.rebel.nl/ Schröder BV]</ref>, a chess software developing company. Ed is author of various chess programs for PCs as well for [[Dedicated Chess Computers|dedicated chess computers]].

On this page I will try to explain some of the secrets of REBEL, I have retired from the competition so I see no need any longer to hide my ideas on computer chess. It's my hope that some of my fellow programmers find something useful on this page and that it might contribute to increase the elo rating of their chess engine.</ref>.
