Beginner Problem - White To Play
r1b3kr/pppp1qbp/6p1/3Q2B1/8/8/PPP3PP/RN2R1K1 w - - 0 1
1.Re8+ Bf8
Forced.
2.Bh6 Qxd5
Or any other legal move. Doesn't matter, because no move will stop
3.Rxf8#
Intermediate Problem - White To Play
r3r1k1/pp1q1pp1/4b1p1/3p2B1/3Q1R2/8/PPP3PP/4R1K1 w - - 0 1
1.Qxg7+ Kxg7
2.Bf6+ Kg8
3 Rh4 d4
4.Rh8#
But 2...Kg8 isn't forced. There are other flight squares, but they all lead to mate:
a) 2...Kf8 3.Rh4 Bf5 4.Rh8#
b) 2...Kh6 3.Rh4#
c) 2...Kh7 3.Rh4+ Kg8 4.Rh8#
Advanced Problem - White To Play
r1b2k1r/ppp2ppp/1bnp1R2/3Np3/2BqP1Q1/3P3N/PPP3PP/R1BK4 w - - 0 1
1.Qxg7+! Ke8
If 1...Kxg7 then 2.Bh6+ Kg8 3.Ne7+ Nxe7 4.Bxf7#
2.Qxh8+ Kd7
3.Rxf7+ Ne7
3...Ke6 4.Ndf4# (or 4.Qf6#)
4.Bb5+ c6
(4...Ke6 5. Qf6#)
5.Rxe7#
So, lot's of branches but none > 5 moves.
Hope to see you all next week!

Note: that cryptic line of letters and numbers you see underneath each board diagram is a representation of the position in what is known as "Forsyth-Edwards Notation", or F.E.N. It's actually readable by humans. Most computer applications nowadays can read FEN, so those of you who may want to study the position, you can copy the line of FEN and paste into your chess app and it should automatically recreate the position on its display board. Or, Windows users can just "triple click" on it and the entire line will be highlighted so you can copy and paste it into your chess app.
