Here is the answer to last week's bonus problem:
Dana-Bashian #3-
1 Qc6 Ke5 2 Qd6+ Kxf5 3 Qf6#
1...Kg5 2 Qh6+ Kxf5 3 Qf6#
1...N~ 2 Q(x)e4+ Kg5 3 Qg4#
Here is David's commentary on the problem:
"My original interest in composing problems came in the summer of 1972 with Pal Benko's composing contest that year. I submitted a complete "A" to "Z" set of letter problems, but none made the cut then. Thirteen years later, I successfully submitted this letter "I" problem from that set for publication in Key Krackers, where it appeared as problem #66. After that publication, I turned to helpmates, and never returned to direct mate composition."
"The problem's themes are a give-and-take key and switchback mates. The key "gives" e5, f5, g5 to, but "takes" f3 from, Black as flight squares. Three of the four mates (1...Kxf5 2 Qf6#) end on f6, the White Queen's origin, and thus those three mates are switchbacks. The fourth mate breaks the otherwise symmetry (about the f-file) of the set of mates."
In keeping with the theme of 'letter problems', Hans Nieuwhart composed a couple of problems in my honor; a 'G' for Gary, and a 'K' for Kevin. He did not compose a 'W' for Ware, but the last problem in my article, Mr. Postman, Have You Got A Letter For Me?,
http://main.uschess.org/content/view/8381/446, was a 'W', and I 'pretended' that it represented my last name.
