Hi, in the simple book I implemented for Kiwi 0.2a, there was the risk of incurring in some classical blunders such as 1. e4 e5 2. Bb5 a6 3. Nf3 => Nc6 from book, or 1. Nf3 Nf6 2. Ng1 => Ng8 from book. To avoid this I play from book only if the start and end positions are both present. The above cases work ok but today I was testing an idea from Dan Honeycutt and played: 1. e3 e5 2. e4 Nf6 3. Nf3 and Kiwi played 3... Ng8?? from the book! Argh! I have now added a check to never play the reverse of a move that was already played... is this solution good enough or there are more subtle bugs to discover? In my book, I only store position hashcodes together with a frequency counter...
