It's nothing special. I have
Msys2 installed and all kind of toolchains with it. A lot of people have this nowaydays.
This was under Win-7 Ultimate.
Thanks Guenther, that is sufficient for little note in README -- I think the setup might be less common than you think, the variety of development tools is incredible nowadays, new tool names jump out practically every time I ask (had not heard of
Msys2 before either).

BTW I have a question, you have already said it uses a fixed depth (4) currently, but I found only a setting which corresponds to (3) in it.
I changed it to (5) in another compilation for not playing immediately but that resulted in depth (6) playing (that was too slow ofc).
It seems then the default depth setting starts from zero counting?
Code: Select all
globals.c/15: #define MONCHESTER_DEPTH_DEFAULT 3
Your interpretation of depth is correct, counting starts from 0. I guess this is fundamental enough to warrant little comment on these
#defines.
I think effective depth 5 (
#define MONCHESTER_DEPTH_DEFAULT 4) should still be tractable for middle-games on most relatively modern hardware, as
./monchester --bench 5 shows 1.077 second time (4711 kN/S) for search of initial position at effective depth 5 on i5-5200U 2.2GHz laptop, but
./monchester --bench 6 takes 15.253 seconds (8138 kN/s) at effective depth 6, so that becomes too much for fast time controls for minimax without alpha-beta as it is implemented. Though there is little heuristic time management for decreasing depth when running low on time, so it is not entirely impossible that Monchester might be able to finish some games at effective depth 6 without getting flagged.
Thanks Taimo. I did just two games now in CuteChess and also had no problems.
I even tried a default depth 5 version now at 40/180s and it lost only one of them on time (my slow hardware).
But for slower Blitz it will be sufficient. I will upload both WIN compilations soon for testing :)
