Aha! Finally got some of you on problem #8 !  Most people thought
that 1.Q-Q5+ or 1.Q-R5+ was the move, but they both lead to mate in
three moves, not two (because of 1. ... N-K4). The correct move is
1.Q-R7!. Then if:
			1. ... P-N4 2.QxN++
			1. ... N-R3 2.N-B6++
			1. ... N-N4 2.N-B4++
			1. ... N-?? 2.Q-R7++

#9: White to play and win:

        BLACK (lower case)
