Saturday Afternoon Chess thread 09-26-2020
Zsuzsa Polgár (HUN)
Thanks to NaCly Dog for filling in while I was away last week.
We will have a fishing thread later. As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.

Intermediate Problem - Black To Play (1201)
Goal: Black can force a mate in, at most, 7 moves

Advanced Problem - White To Play (1200)

Beginner Problem - Black To Play
5rk1/p2p2bp/1p2p3/6p1/2P2Bn1/1PNQ1PPK/P4q1P/3R4 b - - 0 1
1...Qxh2+!
2.Kxg4 Rxf4+
3.gxf4 Qh4#
Black had to remove not just one, but two obstructing pieces to force mate.
Intermediate Problem - Black To Play
r6k/6pp/2pN2r1/b1P5/PnQ1p3/1B2Rp2/1BPq1PPP/4R1K1 b - - 0 1
1...Rxg2+
2.Kh1
Not 2.Kf1? Qxf2#
2...Rxh2+
3.Kxh2 (not good is 3.Kg1? Qxf2#)
3...Qxf2+
4.Kh3 Qg2+
5.Kh4 Bd8+
6.Bf6 (6. Kh5 Qg5#)
6...Bxf6+
7.Kh5 Qg5# 0-1
Advanced Problem - White To Play
8/q1pB4/pk3K2/3p4/PN1P4/8/4P3/8 w - - 0 1
The key to this problem is recognizing that Black is backed up into a corner and his pieces are kind of stepping on each other.
1.a5+ Kb7
My chess app decided that 1...Kxa5 allowing the fork was the better option. I played it out because I saw that if I wasn't careful, Black could free up one of his pawns. 2.Nc6+ Kb5 3.Nxa7+ Kc4 4.Ke5 c5 5.e3 Kb4 6.Kxd5 c4 7.Ba4! c3 8.Bc2 a5 9.Nc6+ Kb5 10.Nxa5 Kxa5 and wins.
2.Nc6 Qa8
3.Kg7
The queen is toast.
3...Qc8
4.Bxc8+ Kxc8
5.Kf6 Kd7
6.Nb8+ Ke8
7.Ke5 Kd8
8.Kxd5 c6+
9.Kxc6 Ke7
10.e4 Kf6
11.Nxa6 for the win.
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.
