|Jun-18-08|| ||MaxxLange: <ravel> after 33. Ng5+ Kg6 34. Bxg8?? Bxd7, White is losing a piece, not winning the exchange. To win the exchange in that line, White has to play 34. Rd6+ and 35. Bxg8|
|Jun-18-08|| ||awfulhangover: Solved it, but took some time to find the Nf8+!|
|Jun-18-08|| ||hedgeh0g: <al wazir> Why wouldn't we be looking for a forced mate? If you can mate, winning the exchange means nothing.|
|Jun-18-08|| ||TrueBlue: <johnlspouge> I believe Ng5+ ties!|
e.g. 33. Ng5+ Kg6 34. Rd6+ Kxg5
35. Bxg8 Bf8 36. Rd1 Bxc5 and black has a pawn and pretty good position in compensation for the exchange
|Jun-18-08|| ||johnlspouge: <TrueBlue> and <SuperPatzer77>, cool your jets, guys. I burned so much time on Ng5+, I thought someone might appreciate the line, even if you did not. IMHO, the presence of a mating line requires no further comment on my preference.|
|Jun-18-08|| ||SuperPatzer77: <johnlspouge>, <TrueBlue> is absolutely right about 33. Ng5+. It can give White some difficulties with R + R vs R + B endgames. I bet my boots most of the Grandmasters would agree more to 33. Rxg7+!! than to 33. Ng5+. Winning exchange sometimes can give White or Black some difficulties. It can help win the game or lead to a difficult draw. |
<johnlspouge> --> In my opinion, 33. Rxg7+!! is simply the best.
|Jun-18-08|| ||ravel5184: <MaxxLange> It's "ravel<<<<<5184>>>>>"! How to remember it: 5 - 1 = 8 - 4. Also did I mention it's (2^3 x 3^2)^2, or 8 x 9 x 8 x 9?|
|Jun-18-08|| ||whiteshark: <ravel5184> 5184 is also the move <e1-h4> in corr. notation.|
|Jun-18-08|| ||MaxxLange: the number keys on my keyboard are broken, and it is killing me inside. THANKS FOR RUBBING IT IN.|
|Jun-18-08|| ||TheaN: 3/3
In such positions, where the defending side has very inactive pieces, it is very obvious that there is a combination, only seeing it can be difficult.
Works in this position. Black somehow blocked his b8 rook completely from defense, giving White semi-control of f8. And that square settles it, giving White the option of this 'sacrifice' which removes the final f8 defender. We will see in a moment that, in truth, this is NOT a sacrifice.
The variation is easy enough, but once you see the needed squares (which are suddenly open), the main variation is easy as well.
As said. A weird placement for a Knight, but the King now only has h8, leaving that important h6 square undefended (which leaded to mate in one in the only variation in this puzzle).
And the pieces are in, and the game is over.
|Jun-18-08|| ||kevin86: I missed this one-because I failed to see the check at f8,I was too fixed on g5. Since the bishop at e8 blocks in the rook-black has NO defense of the f8 square. |
Black has NO defense to the mate threat.
|Jun-18-08|| ||YouRang: Gak! Once again, I was too hasty.
I thought 33.Ng5+ (exploiting the pinned h6 pawn) forced 33...Kh8, after which I have the pretty 34.Rxh6+ Bxh6 35.Rh7#. Feeling clever, I evidently decided that I didn't need to check for escapes.
Of course, black escapes easily via 33...Kg6. :-p
|Jun-18-08|| ||ravel5184: <MaxxLange> How come you were able to type the 5 in Ng5, the 6 in Kg6, etc.?|
|Jun-18-08|| ||spongeworthy: hmm..train of thought here -
Material is even but black has the two bishops.
Black's position is cramped due to pins along the 7th rank and h file.
If white plays 33. Ng5+ it would exploit the situation somewhat..but how?
Black would be forced to move his king to one of two squares, g6 or h8.
If 33 ..Kg6
34. Rd6+, Kxg5.
35. Bxg8, wins the exchange.
If 33 ..Kh8
34. Rxh6+, Bxh6
Thats a sneaky mate. I'm wondering if there is a sneakier mate in the 33 ..Kg6 line.
I dont see it.
|Jun-18-08|| ||spongeworthy: looks like i missed it...|
|Jun-18-08|| ||Marmot PFL: Didn't take long to solve this, and I would bet black, who was a very good GM, probably saw it too right after Be8. Alekhine always said to be cautious when playing any move that cuts the link between two rooks on the back rank. (That's my excuse for missing the winning Bc8 a few days ago).|
|Jun-18-08|| ||patzer2: For today's puzzle solution, it's mate-in-four after 33. Rxg7+!. If you need it, see <dzechiel>'s and other posts for the forced mate sequence which follows.|
|Jun-18-08|| ||MaxxLange: <ravel5184> Iron logic!|
No offense intended, I was just in a hurry to get out the door when quoting you earlier.
|Jun-18-08|| ||DarthStapler: I didn't get it|
|Jun-18-08|| ||johnlspouge: <TrueBlue: <johnlspouge> I believe Ng5+ ties!>|
Now that I have more time, I looked at the position further with Toga (which is virtually useless here, except that it can make good short-term suggestions for human evaluation of the long-term prospects). I agree that Ng5+ probably ties.
|Jun-18-08|| ||MaxxLange: Suetin outclassed this guy so hard - KN to QN1 on move 6 (a good argument for algebraic notation!) in an English, trading Queens early, and then going in for a beautiful R+N+B midddlegame mate before move 40. AFAICR, Suetin is mostly known as an opening theoretician, and this game does not make me doubt that.|
|Jun-18-08|| ||MostlyAverageJoe: Darn, missed it - temporary chess blindness.
To add insult to injury, my 8-year old solved it in about 20 seconds...
|Jun-19-08|| ||cyruslaihy: it took me longer than ususal for a medium level puzzle, i looked for 2 min and cannot find a win after Kg6, then i switched to other things and find Rxg7 after another 2 min|
|Jun-19-08|| ||ravel5184: <MaxxLange> Thank you!|
Never argue with <ravel5184>, he's "always" right.
|Dec-16-16|| ||clement41: Cute mating sequence at the end|
