1)Some details about my source code
Most of the code is the move generator and it is clearly not taken from TSCP.
I copied some names of varaibles and I use similiar search rules *for now*
I also use similiar structure in the main function but it is not a code that
I started by changing TSCP.
2)If you do not want to answer directly to my question
you do not have to answer me but
I still expect at least to explain how do you expect David to understand it.
Do you expect David to understand it because of previous knowledge about your
code that you sent him by email or maybe because of previous knowledge about
Crafty's code or another free code?
