My respect to Eugenio Castillo for his late apology. It seems that he had a hard time and a long fight to decide so. It was a severe offence of Eugenio, i understand that routines like NextMove have another quality than some cray like bitscan routines or moveInput. Eugenio obviously used Crafty framework as a toolbox for the bitboard infrastructure and parts of move generation and even minor parts of eval. He was, probably due his naivety, not fully aware of the cloning issue or did repress it in some way, after receiving no answer from Bob after some tries. Didn't Dann Corbit mention Eugenio mailed Bob about that issue, but Bob didn't receive for what reasons ever? It is difficult to quantify for me, but it seems that most of ElChinitos strength was not based on Crafty but on Eugenio's own search and most parts of it's evaluation. So i respect his decision to don't make ElChinito open source and i suggest to give ElChinito a second chance after some time, until Eugenio assures that no more parts of crafty are inside - IMHO.
