However every time Fritz play white, tabulation occurs to >the first move (in rated games). Why would Fritz assess g3 differently when you lose with this move? I assume that Fritz changes the evaluation of the responses to that move. The learning only affects Fritz's moves, ie. a poor result (a loss against you for example) after 1.g3 d5 means that the value of d5 is reduced and e5 might be tried the next time you play g3. If Fritz plays white and wins or loses with 1.e4 then the weights will change for that move, but not the weights for your response. In engine-engine matches where two engines use the same book, both engines learn. So the weights of all the moves are changed. That's why it might be a good idea to have separate books for both engines. Regards, Mogens
