| May-09-16 | | starry2013: I saw the possible fork and the sacrifices but somehow didn't manage to combine the right things in the right order. Maybe I should stick to chesstempo their puzzles seem to fit my mind easier. |

| May-09-16 | | Cheapo by the Dozen: Not your typical Monday.
Honestly, since it was presented as a Monday puzzle, I did it so quickly that I didn't check Kh3. |

| May-09-16 | | CHESSTTCAMPS: Black is down an exchange, but can set up a royal fork to secure a winning position. After 16...Rxf2+!, white can't save the game: A. 17.Rxf2 Ne3+ 18.K moves Nxc2 wins
B. 17.Kg1 Rg2+! 18.Kh1 (Kxg2 Ne3+ is similar to A) Rxh2+ 19.Kg1 c4+ 20.Rf2 Qxf2# C. 17.Kh3 Rxh2+ 18.Kxg4 Qe6+ 19.Kf4 (Kg5 Bh6#) Bh6+ 20.Kf3 Qe2# C.1 19.Rf5 gxf5+ 20.Qxf5 (Kf3 Qf2+ 21.Kf4 Bh6+ 22.Kxf5 Rh5#) Nf6+ 21.Kf3 Qe2+ 22.Kf4 Bh6+ 23.Qg5 Bxg5+ 24.Kxg5 Rh5+ 25.Kf4 e5# C.2 19.Qf5 gxf5+ 20.Rxf5 Rh5! 21.Kxh5 Qxf5+ 22.Kh4 Bf6# I suppose the game goes 16... Rxf2 17.Resigns |

My sentiments exactly! |

| May-09-16 | | Sally Simpson: This is a wonderful piece of chess.
Teachers needing an example to encourage students to look deeper when playing combinations and beware of the 'Sting in the Tail' need look no further. It started here when White saw the undefended b7 Bishop and the Knight fork pattern on e6.

Hi Penguincw,
"I am surprised this game continues after 18...Nxc2, as white plays 19.Nc4. Personally, I'd play 19...bxc4." The whole game is a feast of instruction. Never relax in a won position still seek the best move. 
click for larger viewRichter was being exact when playing 19...Qe6. It leaves the a1 Rook and the c4 Knight hanging. If Black takes on c2 20.Rxc2 Qe1+ Kg2 Qe4+ picks up the c2 Rook. Good player Richter. Great writer. ' "Chess Combination As A Fine Art" Edited by Golz and Keres is a collection of Richter's articles and instructive puzzles. One of the best books ever written covering this subject. Highly recommended. |

 | | mjmorri: The opening moves appear to be fairly standard. Perhaps White went wrong with the 12.e6 tactical idea which is seen in some openings but obviously does not work here. |
|
| May-09-16 | | WorstPlayerEver: I really think this one is too hard for a very easy puzzle. Took me at least two minutes to find the fork. |

I would have agreed, but last Monday was not your typical Monday either. I suspect that cg.com has decided that Mondays were too easy and decided to make them a tiny bit more challenging.> -------------------
For Kurt Richter, it was a Monday puzzle.
Seriously, what I think might have happened is that this was also used as a Monday puzzle back in 2004. Those were the early days of POTD, and the now expected progression of difficulty was not always followed. By today's standards, this is probably a Wednesday. |
|
| May-09-16 | | roentgenium: Mondays appear to have gotten harder indeed - multiple side lines and needing to find mate 5 moves in advance used to be the domain of Tuesday and even easier Wednesday puzzles. I was not able to see the mate after 16...Rxf2+ 17.Kh3 Rxh3+, because I did not see the power of the Black Bishop to deliver checkmate on the c1-h6 diagonal. Instead, my attempt was 16...Rxf2+ 17.Kh3 Ne3?! which leads to the following diagram:
click for larger viewHere, 18.Qb3+?? fails due to 18...c4 19.Nxc4 Qe6+ with mate to follow. However, White now has 18. Qe4!, protecting against Qe6+ and threatening both Qd5+ and Qxe3, and I can't work out how Black can do more than win back the exchange here. |
|
| May-09-16 | | yadasampati: <roentgenium> After 16...Rxf2+ 17.Kh3 black has 17 ... Rxh2+! 18. Kxg4 Qe6+ and white is finished |
|
| May-09-16 | | YetAnotherAmateur: What happens when white accepts the rook is obvious enough: 16. ... Rxf2+ 17. Rxf2 Ne3+ wins the queen. More interesting is what happens if white refuses, but it's clear that Rxf2+ doesn't lose, e.g. 17. Kh1 Rxh2+ 18. Kg1 c4+ 19. Rf2 Qxf2# |

 | | kevin86: The P at f2 prevents the fork at e3, so it must be removed. Black wins queen and pawn for a rook. |

The point of the puzzle is to find that sacking the rook leads to the fork. If you find that you have the puzzle. It is important that many here try to go down every line, but regardless, if those lines are not refutations of Rxf2 as the best move then that is how the level of the puzzle is established. |
|
| May-09-16 | | Marmot PFL: Still within beginner level but took a bit longer than the average Monday problem. |
|
| May-09-16 | | JimmyRockHound: I thought about 16.., c4 first so as I could mate with the Queen and Knight but then thought about the Rook on f1 so then Rxf2 first would do the trick. |
|
| May-09-16 | | YouRang: Easy once you see the K+Q fork. Remove the defender and boom! |
|
| May-09-16 | | RoyalPawn: It didn't take me that long when I realised that it was black to move. I consider first if it was a spoiler white to move as if you do nothing the forced forked it is coming! |
|
| May-09-16 | | thegoodanarchist: < cow: ...
I suspect you guys are overthinking this. > I was <forced> to overthink <on a Monday> to solve it. Are there no days left for being lazy on cg.com? What is the world coming to?? |
|
| May-09-16 | | WorstPlayerEver: I thought I could handle this Monday puzzle. Now my brain is totally wrecked. Thank you, CG! |
|
| May-09-16 | | morfishine: Very nice post here <Sally Simpson>, reminds me very much when I was working hard on my own game ***** |
|
| May-09-16 | | stst: No instant kill, but still R-sac Monday will get it rolling... 16..........Rxf2+
17.RxR Ne3+ forks K & Q ==> Q lost
OR, to delay the Q loss,
17.Kg1 RxR+
18.KxR Ne3+ forks K & Q -- same thing!!
The config is so nice for the Black N, position just right for the fork to materialize in either line. |
|
| May-09-16 | | stst: <I suspect that cg.com has decided that Mondays were too easy and decided to make them a tiny bit more challenging.> yes & no.... challenging may mean different things...to find the best move to achieve: the usual checkmate
gain in material
gain configuration/positional advantage
stymie the opponent
slash the opponent's fighting power
etc etc
the more hidden, the more challenging...I guess |

One of the best books ever written on the subject. Highly recommended.> That's a succinct and excellent review of the book and I am seriously considering purchasing and looking through it notwithstanding the fact that I spotted Rxf2 and the fork almost instantly. Thank you.# |

 | | gawain: I really liked the King hunt that ensues if he tries to run via 17.Kh3 Rh2+ 18.Kxg4. 18...Qe6+ here is a lovely move. |
