Diagram:
White: Kh7, Bh2; pawns - a5, d6
Black: Ke3, Rf1

White has a pair of dangerous passed pawns, but Black is not
without resource, hoping that his active rook will save the day.
White begins prosaically enough, in the expectation that Black will
be unable to cope with a brace of racers.

1 a6/i Ra1!/ii 2 Bg1+ Rxg1/iii 3 Kh8!!/iv Rd1 4 a7 Rh1+ 5 Kg8!/v
Rg1+ 6 Kf8 Rf1+ 7 Ke8!/vi

i) Black is not to be scared
ii) The strongest. After 1...Rf8 2 Kg6, Black is beyond help, as is
easily seen. After the active 1...Ra1!, Black threatens to play
2...Rxa6. On top of this there will be no joy for White in 2 d7? Rd1
3 a7 Rxd7+ - check! What is to be done now? A surprising
combination comes to the rescue.
iii) The capture is forced, as otherwise 3 a7 is decisive. Which
pawn is the better to advance? Hamlet himself would be hard put
here to choose between "d-pawn or not d-pawn." The true answer
tests our belief: neither!
iv) Here it is, that study move in all its glory! Now it is all over!
v) But not 5 Kg7?? Ra1 6 d7 Rxa7 with a pin. The seventh rank is
taboo for the white king!
vi) Black has no choice. He lays down his arms.
