Answers for Puzzles #15
Correction:
This puzzle has some errors. The top board is the Chaturanga board, and the question should be changed to read: "Mark H. is about to win one game in two moves, and the other in three."
141 pages, from which you pull the sheet that has pages 5 and 6.
However, if book binders ever started with the odd pages on the left (i.e. the inside of the cover rather than the cover) then the answer WOULD be 142 pages, tearing out the sheet with pages 76 and 77.
