Hi Paul

Sorry to jump onto your question to Nisse but I thought you might be interested in my quick response.

On 'Friendly' mode I have found that if Stockfish evaluates that you are behind in the early middle game it will give you a chance to catch up by making a meaningless move with its black roook on a8 moving to b8. It will then retract the move a few moves later. This has happened to me quite a few times.

On 'Challenger' mode I once missed Stockfish mating me in one. As soon as I played my move I saw mate but for some strange reason Stockfish ignored the mate and made another move. I took back both our moves then replayed mine again out of curiosity and this time Stockfish delivered mate.

On 'Expert' mode I haven't experienced any bizarre play by Stockfish only that I feel that the Centaur isn't a beginners chess computer far from it. Even on the quickest time level on 'Friendly' mode it plays quite a decent game for about 75% of the time which would give a beginner no chance.

I personally do like the design of the board especially the size but I'm glad that I only paid £200 for mine. Plastic doesn't bother me whatsoever as one of my all time favourites in my collection is the CXG Super Enterprise.

Hope this helps a little.
