Sacrifice Games Search Tool released

[pohl4711]

I proudly release my Sacrifice Games Search Turbo Tool, which is a huge leap forward, compared to my Agressive Games Search Tools.

The new tool can search for sacrifices from 1 pawn sacs up to 5+ pawnunits (rook-sacs for example(!!!)). And it can additionally build a statistics.txt file about all found sacs in pgn-file. And it finds a lot of (uncommon) piece-patterns of sacs more, than the AGS-tools do. Hint: If you still want to use the AGS-tools, re-download them: pgn-extract had a severe promotion-bug, which now seems fixed in the latest update-version, which I included in the AGS-downloads...

IMHO, this tool can be very useful especially for engine-developers, if they want to make their engine play more spectacular chess. Because the SGS-tool statistics can measure this really precise...

Here an example: Stockfish compared 2 versions: 220205 (latest version, which I tested for my SPCC-ratinglist (7000 games) before the new nnue-net architecture was implemented. And 7000 games (same opponents) of SF version 220210 (first version with new nnue-net architecture):

You can see a clear progress of the number of sacs played by the new net-architecture (!):

Here the statistics by my new SGS-tool:

Old net-architecture:
Source pgn-file: SF_220205.pgn
Number of games found in the source file: 7000
Max. allowed length of games, investigated: 100 moves

New net-architecture:
Source pgn-file: SF_220210.pgn
Number of games found in the source file: 7000
Max. allowed length of games, investigated: 100 moves

Thank You!

I found a serious bug in the Sacrifice Games Search Tool (searching for 1 pawn sacs for black was complete broken)...

I fixed it - Please redownload the tool. I am very sorry. Additionally I lowered the piece-limits for all sacs, so sacs can be found later in a game, now.
