103rd Amateur Series Division 1

[Chessqueen]

I wonder if there would be any difference with this time control instead ===>2 minutes with 12 seconds increments.

Unlikely.

This is my 2nd experiment, and you are correct there is NOT too much difference between 4 moves depth and 8 moves depth Opening Book with the top engines and changing the time control to ==>2 minutes with 12 seconds increments
Note: Here is the score so far, using 2 minutes with 12 seconds increments

9.5 - Stockfish 16 64-bit (Using 4 moves depth)
4.5 - RubiChess 20230918 64-bit (Using 4 moves depth)
3.0 - Berserk 11.1 64-bit (Using 4 moves depth)
1.0- CS Tal 2.00 64-bit (Using 8 moves depth)
1.0 - Caissa 1.12 64-bit (Using 8 moves depth)
1.0 - Koivisto 9.0 64-bit (Using 8 moves depth)

The top engine will gain automatic promotion and the bottom engine will face automatic relegation. Any other changes of division will be at my discretion and may not necessarily involve playoff matches.

Congratulations to the Stockfish team for the convincing victory.

Thanks to all who took an interest.

Since Stockfish is way ahead of the other competitors on this list it would be interesting to see another tournament with these 6 engines, and since Stockfish will not be competing the result could be a little different. The time control could be shorter like 2 Minutes plus 12 seconds increment. Why you are not given a copy of Torch ?

The reason why I believe that testing engines with 4 moves Opening is more effective than with Openings that are deeper like 18 Moves Opening is because with 4 moves there is less chances of the opening to have weaker lines variations and to benefit one side or the other
