| Feb-12-07 | | Tactic101: No, I'm certain I would see this over the board as well. Well, not the Nxf2 perhaps, but definately Rh1+. I'm done this before about 5 times, but I can't deny its wonderful to get a chance to sacrifice material for a mate. |
|
| Feb-12-07 | | flott: Well, being no black queen on the board, the usual monday-queen-sac becomes a rook sac. |
|
| Feb-12-07 | | Beancounter: To answer rotgut, I'm guessing, but i think white had no clue about the Anderssen's threat and was aiming for a mate on g7. Hence he wanted to retain his bishop. |
|
| Feb-12-07 | | laskereshevsky: So easy...i solve it until i clicked on for enlarging the board and the page was in blank........:) A CURIOSITY: watch the position after the white's 21° move....and tell me if somebody could be ready to stake even a single PENNY in black's favour........ |
|
| Feb-12-07 | | Fisheremon: White made three mistakes: 34.Qxa7?! (better 34.Qf4 keeping minimal advantage), 35.Kh2? (a blunder), better 35.Bf1 with equality, and the greatest one 38.Kh2?? leading to a mate in 3. |

| Feb-12-07 | | zb2cr: I love Mondays. Easy puzzle, saw the answer in under 5 seconds. For those who complain about posts giving times, there is a point to measuring such things. If you can't see a forced win under simulated game conditions (not moving the pieces) in something like the time you would have in a normal game, this is telling you something about your board vision. |
|
| Feb-12-07 | | RandomVisitor: It seems that 22.Be2 b5 23.Rxa7 is the simplest plan for a White victory. 21.Be5 is also good for White. |
|
| Feb-12-07 | | micartouse: CT Art calls this theme "Distraction" or "Distraction of the pieces guarding the most important files". I don't know if that's a universally accepted term though. It seems to me like deflection, distraction, and decoy all pretty much mean the same thing although I'm sure they're different. |
|
| Feb-12-07 | | Rubenus: <ianD> That depends. I solved the puzzle very fast because there was a similar mate in one game I played (I won!). One day I even missed the Monday completely. And I wonder why there are ALWAYS people on Monday who say that the puzzle is too easy. MONDAY SHOULD BE EASY! |
|
| Feb-12-07 | | YouRang: I would call it a deflection. The key point of a deflection is that we are forcing a piece to move away from a square such that it is no longer able to perform the important function that it had been performing there. Whether that function was carried out by guarding, blocking, threatening to block, or some other tactical theme, doesn't change the fact that it's fundamentally a deflection. Sometimes creating new terms for every variation isn't helpful, IMO. Anyway, a nice easy Monday. :-) |
|
| Feb-12-07 | | poachedeggs: Where does white go wrong?? His attach stalls after he exchanges his rooks for the black queen and he seems to collapse completely after going pawn hunting with 34.Qxa7...My sense is that it all started to go terribly wrong with 19 Ne7+...any thoughts... |

 | | kevin86: "Rainy days and Mondays always get me down"-The Carpenters 1970s. At least,there is an easy puzzle to answer. In today's puzzle,one rook is sac-ed to open the path for a second rook to mate. 38 ♗xf2 may not save the game-but at least white doesn't get mated in three. |
|
| Feb-12-07 | | Fisheremon: <RandomVisitor: It seems that 22.Be2 b5 23.Rxa7 is the simplest plan for a White victory. 21.Be5 is also good for White.> Tracing back the game one could make the following comments:14...Be6?! (14...Re8 was more natural)
16...Ne8? (16...Ne4 could more or less follow Black's plan with previous moves leading possibly to an endgame with a pawn down for Black, but with opposite Bishops). After this the game was lost for Black: 21.Be5! (as you noted) leads to a quicker win, or 22.Be2 still winning (as you noted too). Instead White gradually made several moves with (?!): 22.Red1, 23.Qe6, 24.Rd8 and finally three mistakes as I noted in the previous post. |

| Feb-12-07 | | uuft: Lovely way to trap a King. Took me at least half a minute coz I have never seen something like this. It helps to realize you need a very forcing move on days like these - although yesterday's puzzle needed dito. God, I felt I was sooo close! :0) 'morrow! |
|
| Feb-12-07 | | nimzo knight: It was easy puzzle. But not an easy Andresson game. By move 27th there was not much too choose.
It seems White just lost focus towards the end. |
|
| Feb-12-07 | | gauer: Maybe it's not really a clearance sack and may it's not really a deflection either.
But is it a classic example of the exploitation of a line interference?
The Rook gives a check, and white is compelled to stop that check, either by a block or capture, or move of the King. Since only the capture is available, black gets a classic Arabian smothered mate pattern, where the King isn't in the corner. |

 | | fm avari viraf: Well, Anderssen delivered a problematic mateeeeeee in two by the tactical theme of deflection. |
|
| Feb-12-07 | | Themofro: Typical Andersson, classic example of clearance sacrifice. |
|

 | | playground player: The solution is easy once you realize the checkmate square is h2, covered by the Knight, and the only escape square is g2, covered by the mating rook. So... the only thing standing between you and h2 is the Bishop in g2, and the only way to move it out of the way is Rh1+, with the spare Rook. Beautiful! |
|
| Feb-12-07 | | wals: Slick work by Anderssen, and for those valiants who do not use a computer...... 39....c5 is also effective according to Fritz,. |
|
| Feb-12-07 | | Marmot PFL: Very easy mate to spot. It's funny that 19th century players either missed them, or saw them and played it out anyway (probably the latter, it was considered good sportsmanship). |
|
| Feb-12-07 | | slowcrawl: I think they should have a day before Monday, but after Sunday, and put puzzles like this one on that day. |
|
| Feb-12-07 | | vibes43: I have heard the term divert or diversion. Overworked Bg2 blocks 39....Rh2# and prevents 39....Rh1# but not diversion 39....Rh1+ which clears path for 39....Rh2#. |
|
| Feb-12-07 | | psmith: <slowcrawl>: "I think they should have a day before Monday, but after Sunday" Don't we all wish... |
|
| May-18-17 | | Sally Simpson: It's a moot point but I was wondering if the game actually played out like it is given. In the Oxford Encyclopaedia of Chess Games' by David Levy the game stops here... 
click for larger view...with White playing 38.Kh2.
Did Anderssen now announce mate in 3 and White resigned. |
