Oct-09-17  goldfarbdj: One of the easier queen sac Mondays in a while.

  patzer2: Mate-in-three, starting with 27...Qxh2+, is easy enough for today's Monday puzzle solution.

White's decisive mistake was 26.Rg1? allowing 26...Bxe3 -+ (mate-in-seven, Stockfish 8.)

Instead, neutralizing pressure with the forcing 26. Qf3 Qxf3 27.gxf3 Bxe3 28. Nxe3 = (0.08 @ 38 depth, Stockfish 8) holds it level.

Oct-09-17  Cheapo by the Dozen: Another Monday, another h-file.
Oct-09-17  WorstPlayerEver: Well, I first looked at g2, but it wasn't working. Seemed to be too clever for a Monday puzzle anyway. Then I eyed at h2..

  al wazir: 27. Qxe3 Rxg2 28. Rxg2 Qxd1+ 29. Qg1 Bxd5 30. Qxd1 Bxg2+ 31. Kg1 Bf3+.
Oct-09-17  saturn2: g2 is well protected but h2 is not. ..Qxh2+
Oct-09-17  stst: Normal MOnday Q-sac:
27........Qxh2+
28.KxQ (forced) Rh6#
or, a self-fooled added move:
29.Qh4 RxQ#
Oct-09-17  stst: <27. Qxe3 Rxg2 28. Rxg2 Qxd1+ 29. Qg1 Bxd5 30. Qxd1 Bxg2+ 31. Kg1 Bf3+.>

If that many moves are necessary, it could NOT be Monday!?

  whiteshark: <27...Qxh2+> and that's it.
Oct-09-17  AlicesKnight: Not dissimilar to some recent pieces; 27... Qxh2+ forces open the R file and after 28.Kxh2, ...Rh6+ leaves only the White Q's intervention to delay mate. Oh! - they played it out - chivalrous.

  cocker: White was weaker by 400 plus Elo points, so made the game last as long as possible.

  patzer2: After 26. Rg1? Bxe3! -+, if 27. Qxe3 then 27...Rxg2 28. Rxg2 Qxd1+ 29. Qg1 (diagram below)


click for larger view

followed up (diagram above) with <al wazir>'s clever 29...Bxd5! -+ (-52.43 @ 33 depth, Stockfish 8) is clearly decisive.

However, with Black to move in the diagram above, the overly efficient computer prefers 29...Qxd5 -+ (mate-in-five, Stockfish 8) 30. c4 Qd2 31. Qf1 Bxg2+ 32. Kg1 Be4+ 33. Qg2 Qxg2#.

Oct-09-17  zb2cr: Mat in three, after 27. ... Qxh2+; 28. Kxh2, Rh6+; 29. Qh4, Rxh4#.

  TheTamale: I'm severely sleep impaired, so I thought I might struggle even with the Monday puzzle. Rather, I got it in 2 seconds... just look for the queen sac, and it solves itself.
Oct-09-17  mel gibson: so easy - I saw it in under 2 seconds.

Good!

Oct-09-17  WorstPlayerEver: <patzer2>

It's all very nice, but chess is ruthless :)

  kevin86: Queen sac at h2, then mate in 2 by the rook.
