Dec-07-15 | | morfishine: <28.Qe8+> Pecking away |
|
Dec-07-15 | | kubbybulin: Ditto Cheapo...my first thought was that Peck never read the classic treatise on back rank mates. One rook on the back rank seems to never be enough back rank defence. |
|
Dec-07-15 | | nalinw: <Moonwalker> ??? The pawn is pinned and cannot promote unless it takes the Bishop - but promoting to a Rook or Queen allows Bb7 and promoting to a Knight allows Ke8. I got it wrong too - had Qg5# forgetting Queens can move backward. |
|
Dec-07-15 | | greed and death: Classic queen sac Monday puzzle.
28. Qe8+ Rxe8 (forced)
29. Rxe8# |

|
Dec-07-15 | | agb2002: White has a rook and a knight for the bishop pair.
Black's back rank is so weak that it allows a mate in two: 28.Qe8+ Rxe8 29.Rxe8#. |
|
Dec-07-15 | | Sularus: Qe8+, RxQ, RxR++ |
|
Dec-07-15 | | poslednieje: This young guy is making progress, a couple of years ago I was playing black against him, a good game from both sides and although I was winning I was impressed and made an extensive analysis of the game for my archive. |
|
Dec-07-15 | | Willem Wallekers: <waustad: I kept looking at something involving the knight until I thought "duh".> Me too, that knight is only there to confuse us. |
|
Dec-07-15 | | Oxspawn: Today's position not hard but I spent a while on the mate in 1. For some time I thought it was Nf6 but that falls foul to one of the many black diagonals. So I think it must be Qa3. |
|
Dec-07-15 | | CHESSTTCAMPS: The x-ray queen sac 28.Qe8+ finishes cleanly. |
|
Dec-07-15 | | patzer2: The most interesting move of the game for me is 17. Ne3!?, enticing Black into the pawn grab 17...Qxb4?! (better IMO is 17...Be6 =). After 18. Qc1! Bg6? (better is 18...Be6 = or 18...Bd7=) 19. Ba3 Qb3? (better is 19...Rxa3 20. Qxa3 ) 20. Bxa8 (+3.48 @ 20 depth, Deep Fritz 14), Black's game is resignable. |
|
Dec-07-15 | | zb2cr: Quite simple to see. Black's Rook on the back rank is defended, so lure it to a place were it isn't defended: 28. Qe8+, Rxe8; 29.Rxe8#. |

|
Dec-07-15 | | patzer2: The position below after 17...Qxb4?! is a good example of an instance when making a threat is better than making an obvious capture. click for larger viewHere the typical beginner novice reaction of "I'll take your's and you take mine" with 18...Nxf5? 19. Qxb2 is a mistake. Instead 18. Qc1!, with the triple threat 19. Nxf5, 19. Ba3 and 19. Rxa8 Rxa8 20. Qxc6, is White's best move. |
|
Dec-07-15 | | patzer2: <whiteshark: All you need is <luft> All you need is <luft> All you need is <luft> <luft> <luft> is all you need.> Didn't think about today's Monday puzzle solution being a back rank mate position, typical of several in the novice book "Bobby Fischer Teaches Chess," until your post reminded me of the Hollies' hit song "All I need is the Air that I breathe" as well as the Beatle's hit song "All you need is love." |

 | | gawain: Clever! The back rank is vulnerable despite being occupied by a defending rook. 28 Qe8+ Rxe8 29 Rxe8# |
|
Dec-07-15 | | YetAnotherAmateur: <whiteshark> 99 luft pawn moves? |
|
Dec-07-15 | | YetAnotherAmateur: Also, <penguincw>, your mate in 1 puzzle (which I also didn't see last week) is not all that hard - the king is stuck, so all you have to do is deliver check with the one piece that can do that and not be immediately captured. Or for those who still haven't figured it out, Ng6#. And yeah, the 6-mover isn't hard at all, because all you have to do is play the only legal move on both sides until white wins. |
|
Dec-07-15 | | saturn2: Mate in two after Qe8 |
|
Dec-07-15 | | kevin86: White mates in two by a decoy/fork. Qe8+ and mate next move. |
|
Dec-07-15 | | daveinsatiable: <YetAnotherAmateur> 1. Ng6, Bxg6.
Not so easy after all.
I didn't get it either, made the same mistake as <Moonwalker>.
The correct answer is given by <Oxspawn>. |
|
Dec-07-15 | | whiteshark: < patzer2 / YetAnotherAmateur > :) |
|
Dec-07-15 | | dfcx: Black still had a chance to save game with
19...Rxa3 20.Qxa3 Qxa3 21.Rxa3 f5 22.exf6 gxf6
another alternative is 19...Qc3 |
|
Dec-07-15
 | | Bubo bubo: Black's back rank turns out to be poorly defended because of the white rook's x-ray effect: 28.Qe8+ Rxe8 29.Rxe8# |
