Solutions Update

Problem 1 - White To Play

r3rn2/p7/3qp2k/1p5n/3P1p1p/1PPQ1P2/P1B2P2/6RK w - - 0 1

1.Qh7+ Nxh7
2.Rg6#

1.Rg6+ Nxg6 2.Qxg6# is also mate, but Black isn't forced to capture the rook. Ibstead of capturing he could do this

1...Kh7
2.Rf6+ Kh8
3.Rh6+ Kg8

...and there's no easy path to a mate.

Problem 2 - Black To Play

6k1/3q1pp1/3b3B/4n3/8/6Q1/5PP1/5RK1 b - - 0 1

1...Ng6!

Blocks the mating threat and now two White pieces are attacked and so he'll lose one of them.

2.Qe3 gxh6
3.Qxh6

Instead of that, I came up with this:

1... Nf3+
2. Qxf3 gxh6

Which doesn't win material. But it does stop the mate.

Problem 3 - White To Play

4r2k/pR5p/6p1/4b3/3B4/2P2K2/1P6/8 w - - 0 1

1.Rb8! Rxb8

1...Rg8 loses to 2.Bxe5#

2.Bxe5+ Kg8
3.Bxb8 and White's material advantage should be enough to win

Problem 4 - White To Play

r1b4k/ppp2Bb1/6Pp/3pP3/1qnP1p1Q/8/PPP3P1/1K1R3R w - - 0 1

1.Qd8+! Qf8

Not 1...Bf8 because 2.Rxh6+ Kg7 3.Rh7#

2.Rxh6+ Bxh6
3.Qf6+ Qg7
4.Rh1 Bh3

Or 4...Qxf6 5.exf6 Nd2+ 6.Kc1 Nb3+ 7.axb3 Bh3 8.Rxh3 f3+ 9.Rxh6# is an alternate line.

5. Rxh3 Nd2+
6. Kc1 Nb3+
7. axb3 Qxf6
8. exf6 Re8
9. Rxh6# 1-0

Endgame of the Week (576)

6r1/p1P2p2/3P3p/8/P7/5k2/8/7K b - - 0 1

This is one of those problems I would never be able to see OTB, but only by working through the position a few times. Maybe a GM could see it, though.

White is about to queen one of his advanced pawns, but his King is positioned poorly. Black takes advantage of this by playing

1...Kf2!

This sets up a mating threat. If now 2.d7, then 2...Rg5 followed by 3...Rh5#.

2.Kh2!

Now Black can't play 2...Rg5 because 3.c8=Q Rh5+ 4.Qh3 or instead 3.Kh3 f5 4.Kh4 and Black has pretty much hosed himself. Instead, Black plays

2...f5!

This moves cuts off g4 as an escape square for White's king and also blocks the c8-h3 diagonal in case of White moving c8=Q.

3.Kh3

Trying to escape via h5

3...Rg1

Oops, that won't work, let's try attacking the rook

4.Kh2 Rg5

There's no stopping 5...Rh5#.

My chess app saw all that and instead played 3.c8=Q Rxc8 4.Kh3 Rd8 which avoids the immediate mate but he loses most of his material doing so.

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 past it into your chess app.
