| May-21-18 | | diagonalley: hmmmmmm "BFTC" (!?) ... that had me puzzled for a while (had it been "BTFC" i reckon i would have got the gist, as it would be a means of escaping the attentions of the dementors) ... so in the end i had to google it ... sad! |
|
| May-21-18 | | saturn2: 38..Qxf2 and mate after both possible answers |

 | | Richard Taylor: Another impetuous move by Sue who was still in the game. I got her years ago from a hopelessly lost position with the old Rh1+ and Q back to h6+ then the B and Q force mate. I'd seen the tactic in a book before the game so I tried to engineer it and it happened...I think I was rook a B and 2 pawns down and had been completely lost for about 15 moves, unless my opponent got careless...And "no one ever won a game by resigning"... |

| May-21-18 | | leRevenant: Happy Pfingsten to those who live in Germany. Enjoy your day off!
And yay, nice easy Monday puzzle. Queen sac and then mate. |
|
| May-21-18 | | malt: We do like Mondays
38...Q:f2+ 39.R:f2 Rb1# |
|
| May-21-18 | | schachfuchs: I've read "Bobby Fisher Teaches Chess" (in a simple german translation) about 40 years ago and I think not only for me these kind of positions with queen sac and back rank mate will always be related to his name. Frohe Pfingsten! |

| May-21-18 | | takchess: Qxf2 Rxf2 the rook is pinned and Back Rank Mate can not be stopped. Happy Monday all. |
|
| May-21-18 | | wooden nickel: Another fun way to win is 38... Bxf2+ 39.Kh1 Bd4!

| May-21-18 | | zb2cr: As with <Cheapo by the Dozen> and <stacase>, this position reminded me of the little book "Bobby Fischer Teaches Chess", with its relentless focus on back-rank mates. The only difficult part was seeing that the d-file Rook should not be the one to give check. Thus, 38. ...Qxf2+. Two short forced mates next move for Black; if 39. Kh1, Qxf1#; if 39. Rxf2, Rb1#. |
|
| May-21-18 | | lost in space: I love Mondays!
38...Qxf2+ 39.Rxf2 (if 39. Kh1 Qxf1#) Rb1# |
|
| May-21-18 | | Once: Now that's interesting. Black had already shown white the combination a few moves earlier. Here's the position after 33. Qc6
click for larger viewNow black plays 33...Rxa5 equalising material. Both black rooks are temporarily en prise but white can't take either of them because of Black's Qxf2+ trick followed by a black rook to the first rank for a back rank mate. So white defuses the back rank mate threat with 34. Rdd1 and after 34...Rab5 the position is pretty level. And yet a couple of moves later white forgets about the threat and walks into it. I'm guessing time trouble. |
|
| May-21-18 | | ChessHigherCat: <Once: I'm guessing time trouble.> Just playing on to mate is a sure sign of time trouble, except in the good old days when the occasional NN sportingly let some hot shot do his thing for the benefit of posterity. Lamest pun of the year: <Drowned Turkey in the Sue of Maroroa> https://en.wikipedia.org/wiki/Sea_o...
(please don't quote me on that!) |

| May-21-18 | | mel gibson: Poor White just made one blunder on the previous move.
Moving that Bishop opened a file for the black Rook. Stockfish 9 says:

 | | gawain: As soon as I noticed that Black's piece on a7 is a bishop (not a pawn) I found the solution. |
|
| May-21-18 | | starry2013: First black seems a move from being checkmated so a check is needed. Second the bishop sac doesn't work as the king can get to safety. So it must be the only other sac, the queen. The other rook can come down to deliver checkmate to the boxed in king. The white rook has to take otherwise the queen delivers mate. But the rook is then pinned by the bishop. |

 | | playground player: Black is at sword's point, so all his moves must be checks--otherwise White will checkmate him. |
|
| May-21-18 | | Madman99X: This puzzle was instructive to me, as I backed up a move, and found 38. Bf8??? which threatens mate, but also single-handedly opens up a line for the B-file rook and hangs the white d8 rook. From this point, anything that defends the mate without losing material wins. The text is obviously the best, but 38... Bxf2+ 39. Kh1 Bd4 40. Rd1 Rxd8 41. cxd4 f6 - Houdini 
click for larger view (for example) is crushing as well.
This is a lesson from my betters to look before I leap. |

The Brazilan I think a little sub-rated.
Nevertherless the rating, It was blunder (probabily time pressure) |

Yep, both points raised by <landshark> earlier. |

<Yep, both points raised by <landshark> earlier.> Are you suggesting that <Once> should change his name to <Twice>? |
|
| May-21-18 | | SpamIAm: I always like games where white puts a piece back on its original square early on (6.Bf1). It's almost a "okay, the weather was nice outside but I'm coming back inside" kind of thing. |
