Beginner Problem - White To Play

3r1rk1/qp3ppp/4b3/4pN2/6P1/2P2P2/1PQP2K1/5R2 w - - 0 1

As many of you discovered, it's a forced mate in 3:

1.Ne7+ Kh8
2.Qxh7+ Kxh7
3.Rh1#

Intermediate Problem - Black To Play

5rk1/3q1ppp/5r2/pp1pQ3/P2P4/2P2bP1/1P3P1P/R3RNK1 b - - 0 1

Mate in 5:

1...Qh3
2.Ne3 Qxh2+
3.Kxh2 Rh6+
4.Qh5

This accomplishes nothing but delay the impending mate by 1 move.

4...Rxh5+
5.Kg1 Rh1#

Advanced Problem - White To Play

8/ppk1p3/2p3Rp/P3p1bP/2B1P3/1P3P2/2Pr1P2/5K2 w - - 0 1

So the general method here is to see that White can get a passed h pawn,

1.Rxg5!

Black should not recapture. Because 1...hxg5 2.Bd3 Rd1+ 3.Kg2 and Black is paralyzed. His rook is blocked in and he won't be able to get his King over to the h-file to stop the pawn from queening.

So, Black is now a piece down. What are his options?

He can try to undermine White's position with 1...Rxc2, but after White secures the passer by 2.Rg6 Rd2 3.Rxh6, Black is pretty much finished: 3...Rd8 4.Re6 Kd7 5.Rxe5 Rh8 6.b4 Rh7 7.Kg2 and wins.

The other option is

1...Rd6

My app found this move, so I decided to see how it could be played

2.Rg6 Rf6
3.Kg2 Kd7
4.Kg3

Here I come... step by step...

4...Rd6

And now I can simplify:

5.Rxd6+ exd6
6.Kg4 d5
7.exd5 cxd5
8.Bxd5 Kd6

I figure I've got a won game at this point, but I played it out for a few moves longer, just to make sure:

9.Bc4 Kc5
10.c3 Kc6
11.Kf5 Kd6
12.Kg6 Ke7
13.Kxh6 Kf6

Black wants to trap my king on the h-file so it blocks the pawn, but I can generate threats on the other side of the board.

14.Bd3 b5
15.axb6 axb6
16.c4 e4
17.fxe4 Ke5

And there it is! The White king is now to move off the h-file

18.Kg5 Kd4
19.h6 b5
20.cxb5 and wins.

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.
