Chapter 12: Trade a rook for a fork

I am reading How to Beat Your Dad at Chess by Murray Chandler. I am blogging to create supporting puzzles in studying the content.

  1. White has a knight on g5 or e5.
  2. Black has castled kingside, and his h-pawn is missing.

A white rook check on h8 (to decoy the black king with a forced move) is followed by the white knight capturing on f7 with check, so that the knight forks Black's king and another piece. 

51) The basic set up, this leading to the ideal fork and the loss of bq.

52) Black has an analogue with bn on e4 and br prepared to sacrifice on the open h file.
53) Black must trade bishops in this example to open f2.
54) White uses the pattern to win bq and bp for wr and wn through forced moves initiated by the rook sacrifice down the h file.
55) The h-file is not open here and if wb opens it, that's a bp en prise or else forced moves lead to the fork.
