Strange artifact of Syzygy format

Post by Dann Corbit »

Given the following 6 man position:
[d]1K6/1R6/1B6/1b6/8/8/8/2b4k w - - acd 66; ce 32702; acs 675; acn 294528; bm Bc7; pm Bc7; pv Bc7 Bd3 Rb3 Be4 Rb4 Bf5 Rb5 Bg6 Rb6 Bf5 Rf6 Bh3 Rf3 Bg2 Rd3 Kg1 Rd1+ Kf2 Rxc1 Ke3 Bb6+ Kf4 Rc5 Bh3 Kc7 Be6 Kd6 Bf7 Re5 Bb3 Ba5 Bc2 Bd2+ Kg4 Kd5 Bd3 Re3 Bb5 Ke5 Bc6 Be1 Bf3 Bf2 Bc6 Rg3+ Kh5 Rg8 Bb5 Kf6 Ba6 Bg3 Bb7 Rg5+ Kh6 Rg4 Bf3 Rh4+ Bh5 Bf4+ Kh7 Rxh5+ Kg8 Bg5 Kf8 Rh8#;

And Stockfish (or Cfish) with access to the complete 6 man tablebase files, it does not find the mate score, even after a 70 ply search.

It must be something strange about this position that causes such a fuss. Nalimov 6 man files find the exact answer instantly, of course.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Stockfish 8 single core with only complete 5 man Syzygy tables on this slowish computer takes just 1 second to get a mate score at depth 20.

It shows a win.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

It shows a win.
By clicking through the mating sequence at https://syzygy-tables.info/?fen=1K6/1R6 ... _w_-_-_0_1
you'll notice many 'only' moves.
Search alone will never find the mating line but by sheer luck.

That's why we use tablebases.
