Steel Fighter by Solista. I 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 opponents 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.

Note: This engine uses special code and specially adapted networks. A change leads to worse results and also incorrect evals.

wow
Thanks Eduard

Btw, I use a Slow Mover of 120 on Lichess (with BIN Book) and 95 on PlayChess (with CTG Book).

Thank you, Eduard!

Thank you Eduard !

Wieder einmal ein taktisch extrem starkes Programm.
Sowohl bei Stellungsanalysen, als auch bei Blitz-Turnieren ist es beeindruckend.

Vielen Dank dafür Eduard !!

The engine has a very fast search. Two variants work in parallel in the default setting. Nevertheless, the engine is almost as fast as SF dev. Anyone can test this with the starting position up to depth 35, for example.

I was surprised by the tactical strength. It is extremely good. In a short test with Ponder On and around 4000 kns, Steel Fighter is +2 ahead after 30 games in my test 2min+1s. Because of two variants, the engine is a bit weaker than SF dev in the endgame, because SF calculates deeper here. In practice on Lichess, I have not lost a game, but won many. See my account SolistaBot.

Played a matchup of engines featuring Steel Fighter with 2+1 blitz time
In my opinion this is a completely weak engine that could win only once.

I don't know how you test (Hardware+Books, it would be nice if you could tell me, thanks) but the engine works well for me. You don't have to use the engine if you don't like it. The computer should have at least 4 cores, otherwise there's no point in playing Random Op. MultiPV=2 like with Steel Fighter. You should also play with Ponder ON and Minimum 7 threads/Engine (16 Threads Machine for Ponder ON). If you don't have that, forget Steel Fighter.

On Lichess I played this live in Blitz (All games can be downloaded --> SolistaBot, members only):


Offline I have this result so far against SF dev.
