| May-26-12 | | James D Flynn: 28……Ne1+ 29.Kg1 Qh1+ 30.Kxh1 Rf1+ 31.Qg1 Bc6+ 32.Rg2 Bxg2# or 29.Q(or R)g2 Rf1# I don’t consider 5 checks during which White had virtually no choice in his replies “very difficult”. |
|
| May-26-12 | | RMKvdS: Woke up, took a quick glance, went to the loo, solved it blind. Kind of proud, but also indicating the puzzle is not that hard for a Saturday. All moves are forced in the sense that something else leads to a quicker mate. |

 | | rhickma4: White looks to have a completely forcing line.
28...Ne1+ 29.Kg1 (29.Rg2 Qg2+ leaves Black the exchange and a pawn ahead) 29.Qh1+ Kxh1 30.Rf1+ Qg1 31.Bc6+ Rg2 32.Bxg2#
Seems easy for Staurday. |

| May-26-12 | | problemist: The wQ checking from d5 and then sacrificing itself at h1 reminds me of a famous chess problem of Herbert Grasemann, Deutsche Schachhefte, 1950:

Mate in four moves |

| May-26-12 | | CHESSTTCAMPS: Black is up a critical pawn, the missing white g-pawn exposing the WK to a decisive attack. White threatens the discovery 29.Ne5, a double attack on Qd5/Nf3 that would win a piece. However, black gets in first with a more deadly discovery. 28... Ne1+! forcing mate:
A) 29.Qg2 (or Rg2) Rf1#
B) 29.Re4 Rf1+ 30.Qg1 Qxe4#
C) 29.Kg1 Qh1+! 30.Kxh1 Rf1+ 31.Qg1 Bc6+ 32.Rg2 Bxg2# |

| May-26-12 | | standardwisdom: Yet another time when I solved a Saturday puzzle completely for everyone to chime and say that yeah, it was an easy Thursday puzzle really. :-) :-) Great puzzle though! Enjoyed bringing the bishop into action, and the rook to play a role. |

 | | chrisowen: Cinch alive in e1+ good king got nowhere to go in level e2 one knight heading for g3 it scatter in engage one thought in con it draw in quick it among in juicy it slide again level it the dead in heat ar in 15th court bad in dilemma delirium it nice in f5 day it down Pf4 in the fray too believe open kingside coming soon for low calc in bind ie 28...Ne1+ hi ne in delve again e1+ 29.Kg1 Qh1+ 30.Kxh1 Rf1+. |
|
| May-26-12 | | Zatrikion: Black should definitely exploit their dominance on the diagonal a8-h1 and start with the obvious discovered check. So: 28..Ne1+ 30.Kg1(forced since Rg2 or Qg2 is met with Rf1#)30..Bc6 0-1
Threat mate cannot be confronted. (31.Rg2 Nxg2 and 32..Ne1) |
|
| May-26-12 | | gaurav33: very very difficult quiz.Qh1+, wow, does't come in my mind. |
|
| May-26-12 | | gofer: I like the idea of <28 ... Bh3>, not using the discovered check immediately, but
instead forcing white to deal with the threat of 29 ... Ne1+ 30 ... Rf1#, but
<29 Ne3> seems to hold the fort. So instead lets try using the discovered check! <28 ... Ne1>
<29 Kg1 Qh1+!!!>
<30 Kxh1 Rf1+>
<31 Qg1+ Bc6+>
<32 Rg2 Bxg2#>
Err. A forced mate in 5, with a queen sac, on a Saturday. Am I dreaming??? |
|
| May-26-12 | | FrogC: I got a Saturday puzzle! First time ever. But I think this is more Thursday level. |
|
| May-26-12 | | James Connelly: (midknightblue) I agree that this should not be a place to brag, but as a relatively new player, I do like to see how others fared compared to myself.
In this case I found the solution rather quickly as well. Knowing that others found it just as handily keeps me humble. |

| | doubledrooks: Black has a potential discovered check, and the best way to execute it is 28...Ne1+, allowing the f8 rook access to f1. There could follow 29. Kg1 Qh1+ 30. Kxh1 Rf1+ 31. Qg1 Bc6+ 32. Rg2 Bxg2# |
|
| May-26-12 | | Patriot: Black is up a pawn.
Black threatens 28...Nb6.
The only knight move that severely limits white is <28...Ne1+>. It took a while to see <29.Kg1 Qh1+! 30.Kxh1 Rf1+ 31.Qg1 Bc6+ 32.Rg2 Bxg2#>. So white must lose the exchange: <29.Rg2 (threatening 30.Qxg7#) Qxg2+ 30.Qxg2 Nxg2 31.Kxg2>. |
|
| May-26-12 | | Patriot: Oops...Ok, 29.Rg2? Rf1# is much better than the exchange! The point is, black is at least better and that was enough to settle on 28...Ne1+. |

 | | kevin86: This masterful bit of magic is great for the eyes-if the eyes are not white's. White cuts off the rook and brings his own in for the kill-even the queen is expendable! |
|
| May-26-12 | | Clodhopper: Yahoo! I got this one. That means for sure it is not as hard as the usual Saturday puzzle. |
|
| May-26-12 | | jhelix70: yeah, maybe a tad easy for a saturday...once you figure out where to put the N in the discovery you have it made. |
|
| May-26-12 | | PugtheThug: yes, ...Ne1+ for a kind of double attack to force checkmate. |
|
| May-26-12 | | Lambda: Took some time because I looked at 29... Rf1+ first, with a similar idea which I think almost, but not quite works. |
|
May-26-12
 | | Dionysius1: Lovely shape to that mate at 32...Bxg2 |
|
| May-26-12 | | Golfergopher: My first thought was 28...Ne1+ but I didn't see the follow up Qh1+. I thought 28...Ng5+ would win.
A)29. Kg1 then 29...Nh3+ wins the queen.
B)29. Qg2 29...Bc6 30.Qxd5 30...Bxd5+ looked like it won the exchange and possibly more. |

 | | DrNyet: From 2004: <cu8sfan on Oct-30-04> "Cool! This is my first successful Saturday puzzle! And a nice one it is. Thanks cg.com for making my day!" |
|
| May-27-12 | | dragon player: The solution is a knightmove, no doubt. But there's only
one winning one:
28...Ne1+
29.Kg1
If 29.Qg2 Rf1#, If 29.Rg2 the same.
29...Qh1+!!
a very nice queen sac, luring the king into the corner. 30.Kxh1 Rf1+
31.Qg1 Bc6+
32.Re4 Bxe4#
Time to check.
------------
Right indeed.
6/6 It's going well this week. |

 | | Penguincw: Ooh, tricky puzzle. I knew the first move had to be a discovered check, but wasn't sure where. Then I decided the knight should control g2, and thought of rather h4 or e1. Probably e1, because the rook on a1 is now cut off. 28...Ne1+ 29.Kg1 Qh1+ 30.Kxh1 Rf1+ 31.Qg1 Bc6+ 32.Rg2. At this point, I paused, as I wasn't sure how to make progress. But oh, 32...Bxg2# 0-1 is a mate in one, since the queen is pinned. It looks like all 3 of black's pieces are under attack, but white gets mated. Wow. |
