Chess engine: Seawall 20230105

-



Chess engine: Seawall,
Rating CEDR=2508  Author - Patrick Heck
This is an [UCI] chess engine. It started as an attempt to build a minimal program that was able to play chess. Over time, it has gained features to make it stronger, but it still implements only a subset of UCI necessary to play games, and there's almost no evaluation.

Some ideas have been borrowed more directly than others; the obstruction difference algorithm is based on the version from [Chess Movegen], while the use of a low pass filter and capture history for move ordering were borrowed from [Stockfish].

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...
