New chess engine: iBlunder 2024-09-05 (Windows and MacOs)

iBlunder - A strong dotnet UCI Chess engine 
author: Tim Jones (GBR)

iBlunder is still in active development so will so expect certain features to be missing or experimental. Also the current release is using a NNUE net trained from self play starting with random weights and is only 6 iterations deep, expect the engine to be much stronger in the coming days as the training does takes a while.

- iBlunder makes use of hardware intrinsics to improve performance. Currently your CPU must support: `Avx2`, `Bmi1`, `Bmi2`, `Popcnt`, `Sse`. Most modern hardware shipped after 2013 should be supported.
- The releases come with a bundled version of the dotnet runtime, however if you want to run from source you'll need the dotnet 8 SDK installed.

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...
