Hello all, just a heads-up that a new release of Moby Dam is available. (...)
Thank you so much for sharing Moby Dam's third version.

It's incredible to see that the "original" Dam has already 20 years (1999)!!

Request to Harm Jetten.

What to do to make the engine continue to play after exceeding the moves for the game and there is no message about the end of the game. For example, I set the program to 15 minutes for 75 moves and after 75 moves it doesn't play anymore.

Hi Krzysztof,

You can set the number of moves to 0 instead of 75; 0 means "unlimited" moves.
Of course Moby Dam will then play a bit faster so by move 75 it will have used maybe 12 or 13 minutes, to account for the possibility that the game will be much longer.

You told it that the game would end after 75 moves, so the program behavior after that is not defined by your match rules. The state of the program and how it thinks and moves at that point is left to the discretion of the program designer.

An idea to extend the move/time format would be to separate multiple formats with a ;, with a * as 'repeat last format ad infinitum'.

E.g. the old time format for games was '50 moves in 2 hours, and then all next 25 moves in 1 hour', which would lead to time format '50:120;25:60;*'.
Or '75 moves in 15 minutes, and then 5 minutes to finish the game': '75:15;0:5'.

But yes you can like you are using Linux or Windows.
