| Apr-11-11 | | stst: No immediate mate, but a Q would be a good feat:
20.Rc8+ QxR (big trouble if not taking this R)
21.Nd6+ forking and taking the Q.
The rest should be easy... |

The best part is the trap at the end which I would of fell for. |

| Apr-11-11 | | patzer2: More interesting and instructive than Today's Monday puzzle solution of 20. Rc8+!, with a winning Knight Fork combination, is Aronian's followup to exploit his material advantage of Queen over Knight and Rook. The followup 23. Qf4! was no doubt planned as part of Aronian's followup, so that after Black defends the pawn attacked on f7 with 23...Ke8, then 24. Qe4  gives the Queen a double attack on the pawns on b7 and a7. After 25...Nb4, Aronian's 26. Rc1! strongly combines offense and defense to set a trap to cleverly exploit the slightly weakened position of the wandering Knight. Here's some analysis using Fritz:
<25...Nb5 26. Rc1!> Also as strong, or maybe even stronger, is 26. Kd1! with similar winning play. <26... g6 >
If 26... Nxc2+, then White wins after 27. Kd2! Nd4 (27... Nb4 28. Qg8+ Kd7 29. Qxf7+ Kd6 30. Qf4+ Kd7 31. Qxb4 ) 28. Qg8+ Kd7 29. Qxg7 , when play might continue 29...Nf5 30. Qxf7+ Ne7 31. Re1 Rc6 32. Rh1 Rac8 33. Rh7 Rc2+ 34. Ke3 Re8 35. Qf6 a6 36. g4 Rc5 37. f4 Rc6 38. Qg7 Rd6 39. g5 b5 40. g6 b4 41. Qf7 b3 42. a3 Kd8 43. g7 Rd7 44. Kd2 Ng8 45. Qf8 Rde7 46. Rh8 Rxg7 47. Qxg7 Ne7 48. Rxe8+ . If 26... Nxa2 (probably Black's best move in a bad situation), then 27. Rd1 Nb4 28. c3 Nd5 29. Qxg7 keeps White's winning edge. If 26... Rxc2, then White wins going away after 27. Rxc2! Nxc2+ 28. Kd2 Rc8 29. Qg8+ Kd7 30. Qxf7+ Kd6 31. Qxb7 Rc7, when play might continue 32. Qa6+ Ke7 33. Qa5 Kd6 34. Qa4 g6 35. Qxc2 Rxc2+ 36. Kxc2 with an easily won King and Pawn ending. <27. Kd2 Nxa2 28. Ra1 Nb4 29. Qh8+!> 1-0 Black resigns in lieu of 29...Kd7 (29...Ke7 30. Qh4+ Kd7 31. Qxb4 ) 30. Qd4+ Nd5 31. c4 with a pin to win the Knight. P.S.: A Knight and Rook are not always at a disadvantage to a Queen, such as, for example, when the side with the minor pieces has passed pawns or mate threats. However, in this case, the rule that the Queen is worth nine points and the Rook and Knight are worth less at five and three points respectively (eight points) holds true. Aronian probably calculated that he could easily win another pawn in the followup, making the combination and followup a little deeper than a regular Monday puzzle. |

| Apr-11-11 | | ClassZPlaya: <An Englishman: Good Evening: Would you enjoy a real challenge? Just looking at the position after 19...Qd7, tell us how White's h-pawn disappeared> Strictly speaking, we don't have enough information from the position itself. However, if you like such puzzles "Chess Mysteries of Sherlock Holmes" is a great book on retrograde analysis. http://www.amazon.com/Chess-Mysteri... |

| Apr-11-11 | | patzer2: <An Englishman: Good Evening: Would you enjoy a real challenge? Just looking at the position after 19...Qd7, tell us how White's h-pawn disappeared> Sure! Assuming the moves 20. Rc8+! through 22...Rxc8 are best play, as Aronian anticipated, then 23. Qf4! Ke8 24. Qe4 creates a double attack on both the b pawn and the h pawn, forcing the win of a pawn. In this case, after the predictable 23. Qf4! Ke8 24. Qe4 Nc3 White plays 25. Qxh7 and the h-pawn has disappeared. |

| Apr-11-11 | | CapablancaFan122: <20. Rc8+!> Cute! Love Mondays! |

 | | Penguincw: I got it right. :) |
|
| Apr-11-11 | | MountainMatt: Gotta be 20. Rc8+. White's only reply is Qxc8 (or lose the h8 rook!), then 21. Nd6+ forking the queen. Is that it? Yes! Monday Monday, you CAN trust that day. :) |
|
| Apr-11-11 | | BOSTER: The most important part of the real combo is to find the tactical idea, the rest is a routine.
Ask himself: do you really need to find something here,or you can see the solution how said <stacase> <Took maybe 5 sec. to see it>?
This is , my opinion, the <weakness> in the <CG> learning process.
But here another opinion <joupajou> < Thanks <CG> for this puzzle>.
I want you give one position from real game to explain what does it mean to find the idea of combo.

I guess this <puzzle> have the Monday level, but in this <puzzle> you have to find the idea before the solution. |

| Apr-11-11 | | David2009: Aronian vs C Seel, 2002 White 20? Level material but White wins Q for R+N starting 20.Rc8+ Qxc8 (20....Resigns is playable but not 20....Ke7? 21.Rxh8)
21.Nd6+ Kd7! 22 Nxc8 Rxc8 (not Kxc8?? Qc3+) and White can choose between 23 0-0-0 and 23 Qg5. This should be enough to win. Harder than usual for a Monday in that I looked first at 20.Qc3 which looks complex but very promising. Some
variations: (A1) 20...0-0?! (very provocative) 21 Nf6+!? (taking the bait) gxf6 22 Qxf6 Rc8 23 Rg5+ Kf8 24 Rg7 winning;
(A2) 20...0-0 21 Nf6+ gxf6 22 Qxf6 h6 23 Rh5 Qd8 24 Qxh6 and Black is clinging on by his finger-nails
(B) 20...Na6 21 Qxg7 Rf8 22 Nf6+ Ke7 23 Nxd7 etc; (A3) 20...0-0 21 Nf6+ gxf6 22 Qxf6 Rd8 23 Rg5+ Kf8 24 Rg7 and the intended Qd4 fails to Qxf7#.
Time to check and enjoy the kibitzes from the regulars who have no doubt all got there
first:

Here's the puzzle position.

In the main line 20.Rc8+ Qxc8 21.Nd6+ Kd7! 22 Nxc8 Rxc8
23. Qf4 was pplayed instead of 23. Qg5
I seem to be the only analyser of 20.Qc6. Looking at it afresh, Black can defend with 20...Nc6 21 Qxg7 0-0-0 top leave

and White is only a Pawn up. |
|
| Apr-11-11 | | patzer2: Black's last best chance to improve appears to be 12...Nc6 = instead of 12...Qb6 13. h5!  .Fritz thinks Black might survive with 18...Qh2 but it looks ugly for Black after 18...Qh2 19. 0-0-0 0-0 20. g4 . |
|
| Apr-11-11 | | patzer2: <Boster> I assume the puzzle position in your last post is White to move, and I'm guessing its solution is 1. Rxd7! Kxd7 2. Qa7! . |

|
| Apr-11-11 | | MaxxLange: <Boster's puzzle>
1. Rxd7! Kxd7 2. Qa7! is the main idea, but you also have to look at the line 2...Bc5 3 Qxc5 Qxc5 4 Rxc5 Kxd7 5 Bb5# |
|
| Apr-11-11 | | tacticalmonster: <Boster>
1) Black king is stalemated
2) Both BQ and b8 rook is unprotected
3) removal of defenders: d7 bishop and a5 queen
a) 1 Rxd7 Kxd7 2 Qa7! Qxa7 3 Bb5#
b) 1 Rxd7 f6 2 exf6 Kxd7 3 fxg7 Bxg7 4 Qxg7+ Kd6 5 Be7+ Kd7 6 Bb4+ Kd8 7 Qe7# |

| Apr-11-11 | | VincentL: Very Easy".
I will be one of the last posters of the day.
This presumably continued 20. Rc8+ Qxc8 (not Ke7 21. Rxh8) 21. Nd6+ Kd7 22. Nxc8 Rxc8 leaving white with Q for R + N. Black´s R and N are undeveloped making the win easier for white. Let´s check. |
|
| Apr-11-11 | | WhiteRook48: 20 Rc8+ and 21 Nd6+ |

| Apr-11-11 | | TheFocus: Yep, very easy. Took all of five seconds today. |
