20000 @ 15+0.05 th 1 SwordFish is a little pet project I have decided to partake in where I am attempting to eradicate unneeded PSQT entries from Stockfish. Please allow this test and all of the games run through to give me an estimate of how far behind (as it will likely be) SwordFish is from Stockfish. Anecdotal tests give me reason to be optimistic, but it is horrible for opening analysis so it needs work regardless.

sprt @ 15+0.05 th 1 I would describe this as the central part of AlwaysDancing. There are still many changes but they do go together in my opinion. The futility margin is from Rainbow Serpent. I have only 100 games so I'm setting priority -2. I do try to get some more games in my own testing.
