I finally managed to produce a crosstable for ALMOST the whole tournament. I did try with Chessbase 14 and Frtiz 15 database but both of them crashed hopelessly. Probably because of the size of the table. These files are based on scid vs pc database software. The only caveat is that scidvspc dropped all the games after 9,737 games. It seems the software has a limitation around that number of games. So this crosstable is missing some 800 or more games. Hopefully it will serve a good purpose.

Went searching for stockfish clones. Found Leptir but my pc antivirus declared it a virus so it prevented the download. Got a workourount but it was a notpad++ sorce code, not a chess engine. Tried to contact the original creator bu his blog was offline (not found).

I also found a new clone of stockfish. Actually,. it looks more like a clone of ShashinChess: Chimera. Unfortunately (or fortunately maybe) it did not work on my pc. It crashed endlessly.

Did found a working one: BlueMarlin 15.7 this one seems to be in working order, so im uploading here for our perusal.

there is quite a few different stockfish clones. I will make a point of searching for them and put them trough the tough crucible of 90m 59 Sec games. This is scratching correspondence chess timecontrols. They will show their mettle, as has been proven by CorChess and others.

NONE OF THEM have proven to be as capable as the original stockfish, SO FAR.

So, there is a war going on in the stockfish world. We shall know which clones are better than the original. Maybe.

At any rate, from my perspective the war of the clones vs stockfish is on.
