Qxh2   {Now comes the key point of the study. White has to move his rook. But where?}   2 Rb1!!!   {A move of amazing depth.

The text move prevents this plan by Black in a beautiful way.}   2... h4 3 Kc6!!   {The point. White is running with his king toward the a8 square. Why? Just wait a moment...}   3... h3 4 Kb7!!   4 ... c4 5 Ka8!!   ({It is important to note here that a move like}  5 Ra1  {would be met by}  5...
