I guess if anything ... this shows the importance of bug free code in a chess program. I think the first to show that was Fruit. While it is nice to have many features and many minor little tweaks to get the program to play "proper" chess ... bugs are the Achilles Heel of any chess program. Each additional improvement needs to come without letting any bugs creep in.
Good job on your program and I must say it is very interesting to follow up on the progress!
Thanks for the comment ! although I am not sure at all Minic is bug free ... To be honest, just after you posted this message, I discovered that null-move was in fact not activated ... This some work to do !
Best regards

While Minic 0.45 is not released yet, here is a Minic no-book depth 30 opening line. What do you think of it ? the queen exchange seems to weaken white side

I do not think much by myself, but 15.a3 look like a weak move; and anticipating the exchange with 15.Qxf5 exf5 looks better. Here is a retro-analysis by Stockfish 10 of this opening, which seems to disagree on almost every move:

Still under 4000 lines - that's impressive for the strength it has. Nice work!

While I am now working on evaluation (mostly king safety and pawn structure) I ran a 40/3 match Minic 0.47 against Fruit 2.1. Here is the results, Minic is just behind.

Minic 0.50 is now available. Should be 2700 on CCRL scale.So please never "test" Minic using those, only for playing purpose.

Thanks Vivien.
Although one remark: Minic doesn't respond to the 'protover 2' command. My own GUI (galjoengui) tries to autodetect the protocol and thinks that Minic follows the 'xboard version 1' protocol. And then, nothing works of course...
