Welcome the newest version!
Velvet is a free open source chess engine written in Rust, licensed under the GPL v3.0.
Behind the velvet curtain...
...Hides a real and strong chess aggressor who can play in an extremely impressive style - you can find examples here.
Velvet, is one of my most favorite chess engines. Why? Because it plays exceptional chess. And while there is no shortage of equally strong or more powerful chess engines - none of them play like Velvet can :)
Here is an example of what latest Velvet is capable to an opponent with a strength of well over 3000 Elo; white: Sting SF 28 AI, black: Velvet-5.0.0.
Having previously sacrificed Rook, Velvet does not hesitate to give extra to Bishop to get the white King!
After playing 700 games, the latest Velvet-5.0.0 has settled at 3342 Elo
This is 55 Elo more than its previous version 4.1.0.
