Re: Chess Computer Vintage (Hardware and Software)

My first computer was SciSys Explorer with full 256 bytes RAM! http://www.chesscomputeruk.com/html/explorer_chess.html. Next Novag Constellation. It was really strong and good looking. And last either Novag Forte B or Mephisto Mondial don't remember sure. From 1990 only PC software.

Re: Some fun positions from my collection

Lc0 is very buggy, because it has no move with syzygy access! But generally tablebases have distroyed this position. SF also sees fast mate in 27 without them. Solved like twice: Analysis by Stockfish 060921: +- (#27) Depth: 53/54 00:00:26 377mN 1.bxc8N+ Kb8 2.Nd6 Kc7 3.Nf5 Kd7 4.Bd5 Ke8 5.Kb5 Kf8 6...

Re: SPCC: Testruns of Stockfish 210906 finished

No progress again! Quite surprising, because there was great (non-NNUE) patch 6.9.

Lc0 against SF14 one core

1 Stockfish 14 +63 +18/=82/-0 59.00% 59.0/100 2 Lc0 v0.27.0 69626 -63 +0/=82/-18 41.00% 41.0/100 1m + 1s and 8 moves book from SF framework. Lc0 runs in GTX card with 2 knps and SF with 2 mnps. I am sure, that even with latest RTX card Lc0 has no chance vs SF multicore. You simply need A100 or V100...
