16. Re2 Qc7 17. exf5 exf5 18. Nh1 {!! A wonderful idea. White
has in mind the manoeuvre Nh1-f2-h3-g5, in conjunction with
Qh5, as a method of assaulting the position of Black's
king. When I first read My System I was so impressed by this
game that I deliberately created situations in my next few
games where the move Ng3-h1 was possible, in the belief that
this mystical retreat would somehow result in a miraculous
increase of energy in my position, irrespective of whatever
else may have been happening on the board at the time.}

quarter? If Black plays 34..axb5 he is mated as follows: 35

Rubinstein elects to surrender a piece but that too is

Chess Artist analysis is completed. In 28. Re5, Keene gave ! whereas Artist gave !!, Brainfish consider this position as very complicated and this is also the move that it found best given 30s of search time.
