I understand that you define correct main line as a winning line for white and you do not care for the fact that the line suggest that the computer does not know how to win. In this case by your definition in KQ vs K every line that does not lead to stalemate or to draw by repetition or draw by the 50 move rule is correct. This is not what I meant by correct main line and the main line that begins with Kb3 in Wac 100 is not defined by me as a correct main line. Uri
