Chess Thread 06-09-2018
Pic Note
A couple three book threads ago, I mentioned the Arthur Conan Doyle Room in the Toronto Public Library. This is the Sherlock Holmes-themed chess set on display. Click on it if you want to see the large version.
As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.
Easier Problem - Black To Play (Ch. 1304)
Hint: You can either deflect or pin one of White' big defenders
3r2k1/1b3ppp/pb2p3/1p6/1P2PPnq/P2N2P1/1B2Q2P/2RR3K b - - 0 1
More Challenging Problem - White To Play (680)
White: "I can force a mate in X moves."
What is the lowest (legal) value of X you can find? And remember, the mate has to be forced, not brought about because Black played a suboptimal move.
Hint: The solution does not involve a sacrificial combination
4B3/2p5/3p4/2pk4/8/2B5/3K4/4Q3 w - - 0 1

3r2k1/1b3ppp/pb2p3/1p6/1P2PPnq/P2N2P1/1B2Q2P/2RR3K b - - 0 1
Mate in 2:
1...Bxe4+!
2.Qxe4 Qxh2#
or 2.Qg2 Qxh2#
More Challenging Problem - White To Play
4B3/2p5/3p4/2pk4/8/2B5/3K4/4Q3 w - - 0 1
White may try 1.Qh1+ and there would follow 1...Kc4 (1...Ke6 2.Qe4#) 2.Qe4+ Kb3 3.Qa4# which, being a mate in 3, is pretty good.
Also a mate in 3 is 1.Qe2 c4 (if 1...c6 then 2.Be7#) 2.Qg2+ Kc5 3.Qc6#
But the best move, the lowest value of X is X=2. Thus:
1.Qb1!
There are 4 responses, all of which mate in 2:
1...Ke6 2.Qe4#
1...c4 2.Qf5#
1...c6 2.Bf7#
1...Kc4 2.Qa2#
Boom.
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.
