103rd Amateur Series Division 1

[Graham Banks]

I am going to hold the same Tournament match but only with the first 6 engines which are on top listed here, I will restrict the LowDraw1000.cgb book to 4 moves depth for Stockfish, Berserk and Rubichess, whereas, the other engines opening Book are restricted deeper to a 8 moves Depth . What is your prediction

Not much difference.

Not much difference.

You are correct there is NOT too much difference between 4 moves depth and 8 moves depth Opening Book with the top engines
Note: Here is the score so far. I should also only use 4 piece tablebases for the last 3 engines and none for the first top 3 engines

9.5 - Stockfish 16 64-bit (Using 4 moves depth)
4.0 - Berserk 11.1 64-bit (Using 4 moves depth)
3.5 - RubiChess 20230918 64-bit (Using 4 moves depth)
1.5 - CS Tal 2.00 64-bit (Using 8 moves depth)
1.0 - Caissa 1.12 64-bit (Using 8 moves depth)
.5 - Clover 6.0 64-bit (Using 8 moves depth)

I decided to continue with my experiment that I said I was going to hold the same Tournament match but only with the first 6 engines which are on top listed here, I restricted the LowDraw1000.cgb book to 4 moves depth for Stockfish, Berserk and Rubichess, whereas, the other engines opening Book are restricted deeper to a 8 moves Depth. Your Prediction was correct Graham.
NOTE: I should replace Clover 6.0 with Koivisto 9.0

19.5 - Stockfish 16 64-bit (Using 4 moves depth)
14.0 - Berserk 11.1 64-bit (Using 4 moves depth)

NOTE: Clover 6.0 was replaced by Koivisto 9.0. I am totally convinced that 4 Moves depth is as good as 8 moves depth when played by the top engines on this list

29.5 - Stockfish 16 64-bit (Using 4 moves depth)
24.0 - Berserk 11.1 64-bit (Using 4 moves depth)
23.5 - RubiChess 20230918 64-bit (Using 4 moves depth)
21.5 - CS Tal 2.00 64-bit (Using 8 moves depth)
21.5 - Caissa 1.12 64-bit (Using 8 moves depth)
20.0 - Koivisto 9.0 64-bit (Using 8 moves depth)

[Graham Banks]

Try a book that allows 12 moves depth, and I doubt you'll see much difference either.

What I honestly believe is that Stockfish, Torch, and Dragon 3.2, can beat any other engines with a book of only 4 moves depth no matter if it is 12 moves or 18 moves deep, because the quality of moves created by those top 3 engines will be as good as any Opening Book created so far, as long as they have at least 12 seconds to think on every move

35.5 - Stockfish 16 64-bit (Using 4 moves depth)
30.0 - Berserk 11.1 64-bit (Using 4 moves depth)
29.5 - RubiChess 20230918 64-bit (Using 4 moves depth)
27.5 - CS Tal 2.00 64-bit (Using 8 moves depth)
27.5 - Caissa 1.12 64-bit (Using 8 moves depth)
26.0 - Koivisto 9.0 64-bit (Using 8 moves depth)

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

Unlikely.
