In Brian Harley's book, Mate In Two Moves: The Two Move Chess Problem Made Easy, after having shown a Queen's Cross problem, he writes the following, "Themes based on multiple direct mates by pieces other than the Q are not of great interest, as a rule; each can give only two mates against a fixed Black K, increased, when he has flights and with the aid of checking keys, to four by a single R or P and five by a B. Direct mates by the pieces
in pairs are not much more productive of a good theme, four mates by two White Kt's being the most frequently seen, and they nearly always occur as incidental to really strategic play. When mates are given by discovery, there is much more scope for the piling up of variations. The White K can be made to discover six mates, either diagonally or laterally, the R fourteen, the B thirteen, the Kt eight, and the P four (disregarding promotion tasks), all these being maxima; (the Q evidently cannot move, discovering check)."

I will show the other two problems, and the Queen's Cross problem, next week.
6 points for sending me a complete variation to each problem, at
garykevinware@yahoo.com , by next Wednesday.
