Peras 3.6.1 is the latest version of a powerful chess engine

Peras - A strong UCI chess engine in Rust, for standard chess, Chess960 and five other variants.
Author: Jesse Sissala  Rating CEDR=3785

Peras is a fascinating and powerful chess engine, with initial tests showing impressive results, as highlighted on our website. Hats off to the talented programmer from Finland.

What's new?
Elo-neutral, and not a regression. A forced move reports a searched score rather than a static evaluation.

Score of v3.6.1 vs v3.6.0: 868 - 813 - 2402  [0.507] 4083
Elo: +4.7 +/- 6.8  (LOS 91.0%), 0 time losses
SPRT bounds elo0=-5 elo1=0, alpha=beta=0.05, 10s+0.1s, one thread
Fixed
With one legal move under a clock, the engine played it at once and reported the static evaluation. Forced moves mostly come in the middle of a tactic, such as out of check, where that number means little, and it is the score the GUI shows. It now takes an exact score of depth 5 or more that the previous search left in the transposition table, for the position or the one after the move; failing that, it searches on an eighth of its usual time target, stopping by a quarter.

We already have the new Fritz 20 program - what does it look like and how does it work?

The purchase process for the download version on the ChessBase website took only 5 minutes. Downloading the files from the cloud was even quicker. The installation itself, which involved five large files, took maybe 7 minutes, including restarting the system and entering the serial number I received upon purchase. The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it. As you can see in the second screenshot, the program interface hasn't changed much; only the icons are different (we've been using Fritz 17 until now). It looks nice, but it's no major revolution. The next two screenshots show engine management and the installation of the UCI chess engine (here, Cataphract 1.1). As you can see, there are no changes. Screenshot no. 5 shows the analysis of some position by Fritz 20 engines. The changes are minimal - it is still very legible. Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
