Chess Thread 02-09-2019

As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.

Easier Problem - White To Play (901)

Goal: White can force a mate in 3
Hint: Force a defender to move

2rqkb1r/pQ4p1/2p1P2p/2p1np2/8/2P2B2/PP3PPP/RN2K2R w KQk - 0 1

More Challenging Problem - White To Play (902)

This is another position where one player, in this case White, resigned in a winning position. He probably saw that 1.f7?? would be met with 1...Rc1+ 2.Ke2 d1=Q+ and threw in the towel. But he missed several lines that actually win.

Goal: use the pawns to force simplification
Hint: break up Black's dominance on the d-file

2kr4/ppp3Pp/4RP1B/2r5/5P2/8/PP1p3P/3K4 w - - 0 1

Easier Problem - White To Play

2rqkb1r/pQ4p1/2p1P2p/2p1np2/8/2P2B2/PP3PPP/RN2K2R w KQk - 0 1

1.Bh5+ g6

Black can't move the knight. If 1...Ng6, then 2.Qf7#

2.Bxg6+ Nf7 (if 2...Nxg6 then 3.Qf7#)
3.Bxf7# (or 3.Qxf7#)

In all of the lines, the key is to force the defending knight out of position.

More Challenging Problem - White To Play

2kr4/ppp3Pp/4RP1B/2r5/5P2/8/PP1p3P/3K4 w - - 0 1

1.f7?? is premature as it allows Black counterplay with 1.Rc1+ 2.Ke2 d1=Q+ and mate to follow shortly.
Much better is

1.Rd6!

There are two ways to capture:

A) If 1...cxd6 then White proceeds with the immediate 2.f7

B) 1...Rxd6 2.g8=Q+ Rd8

3.Qxd8+ Kxd8
4.f7 Rf5
5.f8=Q+ Rxf8
6.Bxf8 Kd7
7.Kxd2 and wins

Another line, which basically comes out the same, is

2...Kd7
3.Qxh7+ Kc8
4.Qg8+ Kd7
5.Qf7+ Kc6
6.Qe8+ Kb6
7.Qe3 Kc6
8.Qxc5+ Kxc5
9.f7 Rf6
10.f8=Q+ Rxf8
11.Bxf8+ 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.

___________

So that about wraps it up for this week. Chess thread tips, suggestions, bribes, rumors, threats, and insults may be sent to my yahoo address: OregonMuse little-a-in-a-circle yahoo dott com.
