Saturday Afternoon Chess thread 12-19-2020

WIM Mona May Karff
There is no movie thread scheduled today, but there will be one later, perhaps fishing, perhaps something else. But regardless, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.
Pic Note
Ms. Karff was quite an accomplished chess master:
She played in three Women's World Chess Championships: 1937 Stockholm, playing for Palestine and placing sixth (won by Vera Menchik); 1939 Buenos Aires, playing for the U.S. and placing 5th (also won by Menchik); 1949 Moscow, playing for the U.S. (won by Lyudmila Rudenko). When FIDE established titles in 1950, Mona May Karff was one of four American women to receive the title of International Woman Master.
Karff, along with Gisela Kahn Gresser and Mary Bain, dominated U.S. women's chess in the 1940s and early 1950s. Mona May Karff won her first U.S. Women's Chess Champion title against Adele Rivero in 1938. She competed and won the title six more times, in 1941, 1943, 1946, 1948 (sharing it with Gresser), 1953 and in 1974 (at age 66). She also won four consecutive U.S. Open titles.
She also spoke 8 languages fluently.

Beginner Problem - White To Play

3n3r/5br1/4pk2/1p1p1p1B/pP1P1N1P/6P1/4RK2/4R3 w - - 0 1
All of Black's moves are forced.
1.Rxe6+ Bxe6
2.Rxe6+ Nxe6
3.Nxd5#
Intermediate Problem - White To Play

r3k2r/p4ppp/1pN5/n2P4/8/7P/P4qPB/R2R3K w - - 0 1
It's technically a mate in 6 only because there's a futile delaying move that only a machine would make. So if you got the mate in 5, you can declare victory:
1. Re1+ Qxe1+
And there it is. Black tosses the queen to delay the mate by one more move. Give yourself a pat on the back if you saw 1...Kf8 2.Bd6+ Kg8 3.Ne7+ Kf8 4.Nc8+ Kg8 5.Re8#
2.Rxe1+ Kf8
If 2...Kd7 then 3.Re7+ Kc8 4.Rc7#
3.Bd6+ Kg8
4.Ne7+ Kf8
5.Nc8+ Kg8
6.Re8#
Advanced Problem - White To Play

2q4R/8/4p3/3kP3/5K2/4P3/2P5/8 w - - 0 1
1.e4+!
Not 1.Rxc8?? stalemate. Now is not the time to grab the queen. Also Premature is 1.c4+? because 1...Qxc4+ and Black gains the initiative.
1...Kd4
2.c3+ Qxc3
3.Rd8+ Kc4
4.Rc8+ Kb3
And now all of White's maneuvering has paid off and the simplification is now very much in his favor:
5.Rxc3+! Kxc3
6.Kg5 Kd4
7.Kf6 Kxe4
8.Kxe6 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.
