Karpov 2294

And another blast from the past. The Karpov 2294, the strongest dedicated chess computer that I own. It is rich in features, such as time control, infinite analysis, and many levels. It also features a very elegant magnetic chess piece set.

Chess for Andoid: version 5.9

I am enthusiastic to announce that I am rolling out version 5.9 of Chess for Android on Google Play. New features include:
Configurable tags for PGN export (player, ELO, event)Ability to offer draw or resign (click king twice to enter menu)Support for Certabo electronic chessboards The application now supports connecting to any of the DGT, Millennium, and Certabo chessboards (let me know if there are others). I have a second instructional video on this topic on YouTube. As usual, looking forward to your constructive feedback!

Chess for Android: Certabo Support

Besides the Millennium and DGT, Chess for Android now also supports the Certabo electronic chessboards. I hope to roll out a next update soon, after more rigorous testing.

Unlike the other boards, the Certabo board does not necessarily come with chess pieces. Instead, a set of 34 identifying chips is provided, which can be attached to the bottom of pieces in any chess set (which means that, unlike the other board, the GUI must first match newly attached chips with the right pieces).
Since I did not have a spare set, I asked my brother-in-law, Gerard Harbers, who just bought a fancy new 3D printer, to print a full chess set for me. He enthusiastically got to work!

The pieces have some spare room at the bottom, perfect for placing the identifying chips.

Fidelity Electronics Chess Challenger

As long as I am making a trip down to memory lane, I remember how happy I was when I got a Chess Challenger for my birthday in 1981. As a starting young chess player, I certainly learned a lot from playing this computer, and I was thrilled when I had beaten the highest level for the first time. It certainly has sparked my interest in chess programming.

After playing for a while, I discovered that if Chess Challenger responsed to e2-e4 with e7-e7 from its random opening book, it could always be beaten at Level 1 through the game shown below. As depicted on the corresponding photo, the Chess Challenger would admit its defeat by flashing all 64 red indicators.
