  spyron: What happens after 36...Bf4?
Jan-01-17  drollere: i am in patzer league, but the rook sac at 21. Rxf7 followed by Qh7+ leaped out after about 10 seconds of evaluation.

my divergence was 26. Bb6+ winning the Q and KN pawn, with the black K out in the open and the black R's blocked by the center pawns.

  YouRang: Following this game with the computer, I see that white had a quicker way to win. After <25...Kxe4>


click for larger view

White has <26.c4!>

The Pc4 is stopping the king from escaping back to d5 and c6, but why can't black just take it: <26...bxc4>?


click for larger view

Because now white has <27.Bg1+!>, and now "escaping" via <27...Kd5> actually runs into an ambush: <28.Qf7+ Kc6 29.Qxf4#!>


click for larger view

Black's best choice after <26.c4> was <26...Kd3>, but this looks awful, for black, and indeed it is.

  maxi: <YouRang: Following this game with the computer, I see that white had a quicker way to win. After 25...Kxe4 White has 26.c4!> Yes, simple and effective. It is the kind of move that is almost impossible for a human to find, and yet a computer can find it in less than a second. Hmmm.

After 25...Kxe4 White has 26.c4!> It is the kind of move that is almost impossible for a human to find, and yet a computer can find it in less than a second.> It is almost superhumanly devious to play a pawn with the intention of forcing the king to capture it and then to leave the square to free the space for your queen.
Jan-01-17  scormus: <YouRang> Excellent, insightful analysis. A masterclass :)
Jan-01-17  Muttley101: Jan did an excellent video on this game, it's on youtube.

Jan-01-17  King.Arthur.Brazil: I answered correctly most the beginning failed on 27.Sd2...Se3+ and Qb3. I missed 31.Qd3 and the final 32.Se1. My headaches don't help much.
Jan-01-17  stst: Quite many choices for 1st game of the New Year! Essentially lock up the Black K within the e6-g8 corner. Cite only one & see if it strikes what Wei picked: 22.Rxf7 KxR (others led to mate sooner)
23.Qh7+ Ke6 (also if K stays on f file, Rf1 will mate sooner) 24.Rf1 Bf6
25.Qxg6 Rg8
26.exd5 Bxd5
27.Qf5+ Ke7
28.Qxf6+ Ke8
29.Bg6+ Bf7
30.BxB+ Kf8
31.Bh6+ Rg7
32.BxR#

as said, there're still other possibilities...let see

Jan-01-17  stst: Oh the Black K tries to flee the other side...
But after 25.Be4... thought a good move to lure the KxB, very curious why White did not capitalize to dis+ with 26.Bb6 (R+) to snatch the Black Q....

Agreed with others that White should have won much quicker (& more elegantly!!)

Jan-01-17  mel gibson: Easiest insane puzzle I've seen -
I saw the move in under 1 second.

the computer DR4 64 bit says:

22. Rxf7 (22. Rxf7 (♖f1xf7 ♔g8xf7 ♕h3-h7+ ♔f7-e6 e4xd5+ ♗b7xd5 ♗d3xg6 ♗d5xg2+ ♔h1xg2 d6-d5 ♕h7-f7+ ♔e6-d6 ♕f7xe8 ♗e7-h4 ♕e8xd8 ♖d7xd8 ♖e1-g1 ♖d8-h8 c2-c3 ♔d6-e6 ♔g2-f1 ♗h4-e7 ♖g1-g2 a6-a5 ♔f1-e2 b5-b4 c3xb4 a5xb4 a3-a4 ♗e7-d8 b2-b3) +3.22/18 157)

  ChessHigherCat: <stst: very curious why White did not capitalize to dis+ with 26.Bb6 (R+) to snatch the Black Q....> 26. Bb6 (R+), Kf4??? 27. Qb3 threatening mate with Qf3, with the Q en prise and the King naked among the wolves, but what's the follow-up if black plays 26...Kf5 instead?

Were you using a stopwatch? Perhaps a sundial?

  ChessHigherCat: I got Rxf7 in a couple seconds (who wouldn't after all the puzzles with the exact same theme?) but that hardly counts as solving the puzzle immediately.

Well unlike other puzzles where I look at them for up to 5 minutes - I saw the first move instantly.
