Go up one level in this thread


Does that mean that we can be sued for using ideas such as using bitboards... or
a 64 bytes array to represent the board?
The only two pieces of code that I have ever copied are:

  1) A few lines to read the input, because I didn't know how to do this.
  2) A branchless assembly version of a 64-bit BSR/BSF for 32-bit processors.

The implementation (but not the original ideas) of typical chess engine search /
evaluation functions are mine... because I don't like reading other people's
code. Do you advice to start sending lots of mails to lots of people asking for
the permission to use their ideas if I ever decide to send my program to a
tournament (or make it commercial)?
All this sounds a bit extreme to me.

Regards,

 Jaime
