Haha, yet another one, why win an exchange with winning position when you can also just play a dubious piece sacrifice. (to be fair it might have almost worked) :P EDIT: Wait I'm stupid, 30.Nxe8 Rxg2+ was a draw, the pieces sacrifice was correct, just the followup wasn't. On the plus side, it keeps ...

I was wondering what a good rating system for a 2 vs 2 chess variant would be. I was thinking Glicko should be a good starting point so I modified it for this purpose. However there are a few problems with that: If everyone starts at 1500 and RD 350 or something like that, the RD goes down only very...

Thanks for including my engine again. If you announce the next one a bit earlier I might get a new version ready. ;) And what a coincidence, next round my engine vs the TarraschToyEngine, which I used to roughly determine the strength of my first version. I've run tons of blitz games between them wi...

On an unrelated note, I was checking some other TB position and stumbled upon this position https://syzygy-tables.info/?fen=6Q1/5NR1/8/8/1q6/2k5/8/2K5_b_-_-_0_1 Why does the DTZ value of the position vs the one of the top move, down the top line look so weird? Am I missing something? The value I se...

Why does the DTZ value of the position vs the one of the top move, down the top line look so weird? Am I missing something?

I am wondering about this: ftp://112.73.74.24/pub/syzygy/7men_testing/KRRPPPvK.txt Longest win for white: 13 ply; 8/8/1P6/RP6/RP6/8/2k5/K7 b - - [D]8/8/1P6/RP6/RP6/8/2k5/K7 b - - Why can white not respond to any move by black with b7? I don't understand very well your question but I ran the positio...

I know syzygy don't always go for shortest mates. My idea is if syzygy somehow did go for shorest mates, those extra moves can potentially save a good amount of space. Mate in 49 versus 60 mean less space used, just a thought. But if you can convert in 40 moves instead of mate in 49 your numbers ar...

I have it working now. It produces this game: [pgn][FEN "k7/2QR4/8/8/8/4N3/2r4Q/1K6 b - - 0 1"] [Annotator "syzygy-tables.info"] { DTZ -62 } 1... Rc1+ 2. Ka2 Rc2+ 3. Ka3 Rc3+ 4. Ka4 Rc4+ 5.

Was that changed recently? I remember SF used to give DTZ values.
It would output all moves and give the DTZ score for each with something like +3, or -2.
Or maybe that was my GUI, not 100% sure.
