P.S. I make a difference between errors in evaluation and failure to follow the
rules of chess. If an engine is unable to find the obvious best move in a
position, I call it a "weakness", and it's up to Chessbase's discretion whether
they want to correct it or not. Evaluation functions are complex things... by
making sure the evaluation is better in one particular situation, the overall
performance of the engine might suffer.

On the other hand, if an engine suggests moves that are illegal, ie moves that
aren't allowed in the standard rules of chess, it's a "bug". No arguing about
it. It should be fixed straight away, and if it can't be fixed the product
should be withdrawn from the market.
