An Octagon Sharktank

[MikeB]

Just for fun...

An Octagon Sharktank, an Easter special running for the next 72 hours, 8 different flavors of the latest bleeding edge Stockfish and derivatives with the relatively "long" time control of a 150 second base with a full 5 second increment - 40 positions will be selected at random ( via script using "jot") from a 200 handpicked positions that were handpicked to foster very sharp play,
Single thread , with 12 games running concurrently on a 12 Core ( real) Mac Pro
256 MB hash
Full 6 Man Syzygy on SSD drive.
All run on Bob Hyatt's csh scripts and match code, totally GUI less and automatic, including positing of results ( using a modified bayeselo) and games (slightly modified)

Fish Participating :
set eng1 = asmfish
set eng2 = corchess
set eng3 = matefinder ( not J Ellis's matefinder - but relatively close)
set eng4 = McCain-dev-042019
set eng5 = shashchess
set eng6 = sugar
set eng7 = stockfish
set eng8 = stockfish-042019 ( same as Stockfish, but it includes features from McCain)

It was kicked off at 12:56 PM today.

First results will be posted in about an here https://www.dropbox.com/s/0xr3pc1gmx7ch ... 1.txt?dl=1 and about every 40 minutes there after.

Alternatively, after every completion of 56 games ( one position with all engines playing white and black against the other engines) - each round will take about two hours https://www.dropbox.com/s/0xr3pc1gmx7ch ... 1.txt?dl=1

Games will be posted here:
https://www.dropbox.com/s/khe6cvvcv5na0 ... s.pgn?dl=1

Note files will be blanked for while , until the completion of games , set by time or by completion round (56 games)

I have all sources of the above engines located or forked on my main Github page :
https://github.com/MichaelB7 asmfish and shashchess are separate repositories, the rest are branches under Stockfish

A few comments - my bad, but I included am amsfish that plays with variety, hence the unexpected poor showing here. After the next round. 20 random positions would have been used - which is halfway through and at this point , I will end it. I had expected Corchess or Sugar to finished on top and I have played more games, one of those engines most likely would have finished on top had I kept it going. IMHO, I believe Corchess tp be the strongest Stockfish derivative for LTC games with Sugar a close second ( and whenever asmfish is current, it is a major force as well) I tip my hat to both Ivan and Marco for their efforts as well large head nod of appreciation to the entire SF development team for making this possible as without SF none of these very fine derivatives would exist period. Will post the final results ( as noted, aborting at 20 positions as soon as it wraps up). May do a threesome with Corchess, Sugar and McCain soon.

Edit : I meant to include cfish as well, will include that excellent SF derivative in the next round as well. So it will be a foursome: Cfish, CorChess, McCain & SugaR.
