End of the Torch Experiement?

 Andrew Grant: "Almost exactly one year ago we announced the release of Torch. We were a bit ambitious at the time, and announced it as the #2 engine, after beating Leela in the most recent Bullet event at CCC at the time. Today, that claim rings much more true, although still has some minor points of contention. Torch has beaten Leela in multiple Bullet and Blitz events in a row; Never managed to win one of the Rapid events; But has beaten Leela in a h2h classical event. Chesscom got into the space out of a need to develop a replacement for Komodo. They needed a strong chess engine which could be used for integrating their other products. Many features on Chesscom, from Game Review, to puzzle generation, to Bots (obviously!) are powered by high quality engines. The goal was always for that. In fact, despite me being the only full time employee working on Torch, a plurality of my time was spent on things not related to Torch's strength. Its a bit self-aggrandizing, but the Tor

New chess engine: Steel Fighter (Stockfish derivatives)

Steel Fighter by Solista.  Eduard NemethI created this engine for playing on Lichess. The engine uses an extremely fast random op. MultiPV mode! With a value of 2 (default) the engine is only slightly slower than Stockfish dev. Positionally, the Enghine plays a little weaker than Stockfish dev, but tactically it is much better. On Lichess, where half of the enemies are non-Stockfish and make more tactical mistakes, you'll have more fun with Steel Fighter. Steel Fighter is also a good addition for short tactical analyses. Download Win 64 Bit (avx2, bmi2, sse41, source code): https://pixeldrain.com/u/Yqp3g6TT Note: This engine uses special code and specially adapted networks. A change leads to worse results and also incorrect ratings. Steel Fighter download

Chess engine: Deep Ripper -1 (Stockfish derivatives)

Deep Ripper (Stockfish derivatives) by Eduard Nemeth Author: " Here is the first official version of Deep Ripper. For now, I have decided on a version that can be used for any hardware. If you only have a few cores, you should set the number of variants to 1 or 2. However, 4 variants are standard (1 to 10 can be set), which deliver very good analysis results on 6 or more cores. Playing on servers is also possible. I hope you enjoy testing." Deep Ripper - 1 download Deep Ripper - 1 download This engine uses the Random Op. MultiPV mode. Here, several variants are examined in parallel and, after e.g. 16 plies, merged into a single variant. This is not the same as the normal multi-variant mode, where all variants are examined separately. The results can be completely different! So it makes no sense to create an identical engine without the random mode.
