Sep-16-19  belgradegambit: I swear I looked at it and assumed it was black to move and that made it an easy Monday puzzle.
Sep-16-19  swclark25: I also thought something was strange, but was happy to also get 34.Rxd5 as the best move for white like several others.

  Sargon: Apologies for the for the confusion with today’s puzzle, ladies and gentlemen—it should read <Black to play: 34...?> rather than White. It has been belatedly corrected.

  Yuridmi: Thank You, Great God Sargon!
We offer you prayers and supplications!

Actually a very instructive anti-Benoni game. Shows how White can get his bum in a sling with just a few non-contact slow moves in the opening when aggression was called for!

Thanks Again Sargon! We love the daily Puzzles!

Sep-16-19  zb2cr: STILL not right. If it's Black's 34th move, the home page diagram should have the White Bishop on g6.

To be sure, the diagram on this page does have the Bishop positioned correctly.

Sep-16-19  WorstPlayerEver: I found this not so easy:

34... Bxf3+ 35. Rg2 Qxe2 36. Bxf7+ Kh7 37. Rg1 Bxg2+ 38. Rxg2 Qf1+ 39. Rg1 Qxf7 40. Qxh4

And then? I got stuck lol

  al wazir: Far too easy for a Thursday/Friday puzzle.
Jan-15-21  Brenin: Is it Monday already? As <Walter Glattke> wrote, 34 ... Bxf3+ 35 Rg2 (35 Qxf3 allows mate on h2) Qxg3 36 Nxg3 Bxd1 leaves Black with R+P for B, and White has no compensation. 35 ... Qe2 also works, though White has some counterplay with 36 Bxf7+, e.g. 36 ... Kxf7? 37 Rd7+ wins for White.
Jan-15-21  AlicesKnight: I saw .... Bxf3+ and thought "There must be more to it on Friday ... seems not. After 35.Rg2 Qxg3 36.Nxg3 Bxd1 there remain the threats of Bf3 and fxg6.
Jan-15-21  TheBish: Easiest Friday puzzle ever. Maybe because it was a Monday puzzle in 2019!

  Messiah: I totally agree with my friends who said this is an unusually easy puzzle for a Friday.

However, it was tricky, because I did not even check for the most obvious moves, once I saw the idea, exactly because it is Friday: I tried to make it work with 34...Bf4 or 34...Rxh2+, which means, in a time trouble, I might have been unable to find the easy win. It occurred numerous times in my laughable career.

Jan-15-21  stacase: Super easy for a Friday. What gives?
Jan-15-21  saturn2: White threatens Qxh4 but after 34...Bxf3 not any more.

And it really didn't take me that long.

  Jimfromprovidence: CG is recycling puzzles from the middle of September, 2019, so I am offering this one from a collection of LA Times puzzles I have accumulated.

This is a clever puzzle of moderate difficulty. It's white to play and win, move 31.

Jan-15-21  Everett: Not best, after the obvious 34..Bxf3 35.Rg2 I chose Qxe2

  agb2002: Black is one knight down.

The black queen x-rays the square h2. Therefore, 34... Bxf3+ 35.Rg2 (35.Qxf3 Q(R)xh2#) 35... Qxe2:

A) 36.Qxh4 Qxg2#.

B) 36.Rdg1 Bxg2+

B.1) 37.Rxg2 Qe1+ followed by fxg6 wins decisive material.

B.2) 37.Qxg2 Qxg2+ followed by fxg6 wins decisive material.

C) 36.Bxf7+ Kh8 (36... Kxf7 37.Rd7+ wins for White)

C.1) 37.Bxe8 Qf1#.

C.2) 37.Rdg1 Bxg2+ wins an exchange at least.

Jan-15-21  mel gibson: It's a Monday puzzle - surely?
Jan-15-21  messachess: Funny mistake.
Jan-16-21  Everett: <RandomVisitor: After 9...Nbd7 white has a good position: >

White often has a good position facing the hedgehog... it just proves treacherous moving forward
