Another good chess problem [Title &quot;The Chess Monthly, 11/1860, Helpmate In 3 Moves (Version)&quot;] 
[FEN &quot;6R1/7q/8/5k2/3K1B2/8/8/8 b - - 0 1&quot;]
[startflipped &quot;&quot;]

Now, in this chess problem by Samuel Loyd, both sides work together for a checkmate.  If Black is to move first, how can White give mate in 3 with Black's cooperation?
Nice one:

 1 Kf6 Ra8! 2 Kg7 Bb8 3 Kh8 Be5#!  (&quot;Indian theme&quot;)
