  An Englishman: Good Evening: What, a Monday with no Queen sacrifice? Or any sacrifice at all?
Nov-06-17  Cheapo by the Dozen: I've always loved this theme.

But then, one of my first chess books was "Bobby Fischer Teaches Chess".

Nov-06-17  saturn2: The weak back rank allows 26..Rf1
Nov-06-17  morfishine: <26...Rf1+>

*****

Nov-06-17  lost in space: I love Mondays!

26... Rf1+ and end of the story

Nov-06-17  AlicesKnight: ....Rf1+ sandwiches the White defending R and drags it away from its support. Mate after exchanges.
Nov-06-17  gofer: I think we should re-wind a little bit <16 Nd5???>. What was white thinking!?! Surely nobody walks into this "trap" at this level!?!

Nov-06-17  leRevenant: What the first guy said.
Nov-06-17  wooden nickel: after 11.Qe2, Black took the pawn 11 exf4. How do we know when to take that pawn in this kind of position? I'm never sure!

Nov-06-17  zb2cr: A mate in 2 following a Rook sacrifice. Must be Monday. 26. ... Rf1+; 27. Rxf1, Rxf1#.
Nov-06-17  patzer2: That (26...Rf1+) was a quick and easy two-move mate solution, even for a Monday puzzle.

White's decisive error was 16. Nd5? allowing 16...Nxd5 -+ (-2.85 @ 23 ply, chessgames.com Stockfish 8 engine). Instead, 16. Nf5 ⩱ (-0.31 @ 20 ply) would have kept White in the fight.

In the opening, instead of 11. Qe2, our Opening Explorer indicates White has had more success with the popular move 11. Kh1 as in the hard fought draw Yifan Hou vs A Giri, 2012.

Earlier in the opening, instead of 6. f4, I prefer 6. Bg5 as in White's wins in A S Rasmussen vs J Ferreira, 2017, Caruana vs Nakamura, 2017 and Nakamura vs I Nepomniachtchi, 2017.

  whiteshark: <26...Rf1+!>, and that's it.
Nov-06-17  lzromeu: 26Qe2, bad monday!!!
Nov-06-17  TheTamale: I saw this instantaneously--the easiest Monday puzzle I've ever encountered. Made me wonder how a master-strength player didn't see it coming. Then I saw that White was not a master-strength player.

  PawnSac: < Caissas Clown: 26...Qe2 takes longer,but is more fun and more in the spirit of Monday. >

also possible is ..Qf2

Nov-06-17  Joseph Blackcape: Very Easy indeed. While Rf1+ mates, almost any Queen move that attacks the e1 Rook again wins too (outside of Qb4 of course) - not only Qe2, but also simple Qa1, Qb1, Qc3, Qd2 and Qf2 all win, since White Queen is completely cut off with not a single move to defend the Rook again and no available checks to win a tempo.
Nov-07-17  ruzon: Even if White gets to take his last mistake back, the best he can do is 26.Rg1 Rxg1+ 27.Kxg1 Qf2+ 28.Kh1 Qf1#.
