73rd Amateur Series Division 1

[Graham Banks]

32.0 - SugaR 1.6 64-bit
32.0 - Stockfish 10 64-bit
26.0 - ShashChess 6.0 64-bit

IMHO there are too many Stockfish clones in the CCRL rating list.

Define clone and define derivative.

Define clone and define derivative.

For me, it's the same concept : copying source code with some modifications.
If 90% (or more) of the lines are the same as the original project, don't test the derivative.
