Most beginner's books are full of errors like these--by no means does this mean that Logical Chess: Move By Move
is a bad book. As Frederick Rhine noted in the previous comments, it wouldn't be surprising for a GM to make the same mistake. (Chernev's error on move 8 is crude enough for me to notice without a computer, or for an alert beginner to catch.)Resignation in a drawn position is fairly rare (I confess that I did it against NM William Aramil in 2001.)
