Chess engine: KhepriChess 3.1.0 (java)

KhepriChess - java (UCI) chess engine

v.3.1.0:
This version features a fairly heavily reworked search, including changes to the iterative deepening function, aspiration window, selectivity, etc.

Some minor changes include letting the engine search longer when the PV changes. Also hopefully fixed a somewhat uncommon bug where, in clearly winning endgame positions (like KQvK or similar), the engine would fall into a 3-fold repetition draw.

48.3 +/- 5.3 Elo in self-play

KhepriChess is a JavaScript (written in TypeScript) chess engine. It uses native 64-bit integers for bitboard representation.

UCI
Use "kheprichess_uci.js" in UCI-compatible applications.
Nodejs is required. Please download the latest version (or the LTS version) [here](https://nodejs.org/en/).
Once node is installed, you can add KhepriChess to a GUI program, like Arena or Cute Chess.
* In [Arena](http://www.playwitharena.de/), the command line should be the path to the nodejs executable. In the "Command Line Parameters" field, specify the path to the kheprichess_uci.js file.
* In [Cute Chess](https://cutechess.com/), the command field should look something like `<Nodejs directory>\node.exe "<Khepri directory>\kheprichess_uci.js"`.

Polyglot
KhepriChess supports the use of a polyglot opening book. Simply place a book file with the name of `khepri_polyglot.bin` in the same directory that the JS file is running from and it will automatically detect and load it.

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...
