No , 30. Nd3 was vital preparaton.
Without it 30 Nf5 Rxf1+ 31 Kxf1 Bb5+ 32 Kg1 gxf5 then 33 Qg5+ Kf8 34 Qg7+ Ke8 or 33 Qh6 f6
The Nd3 prevents Black playing Bb5 with check , thus opening up an escape route via e8.
|May-30-07|| ||eblunt: Instead of 30 .... Rd1 , 30 ..... Rc7 and Black is has a comfortable advantage IMO.|
|May-30-07|| ||Kleve: At first I tried the obvious Qh6, but then tried Bh7???. Totally overlooked the knight fork threat!|
|May-30-07|| ||newton296: I saw nf5 pretty quick here, the hole at g7 is pretty glaring. I figured adams would resign as soon as he saw nf5!! and he did.|
|May-30-07|| ||melv: I tried Qh6. I tried Nxg6. I looked at Ndf4. I found that black has no immediate forced back rank mate. Finaly I saw Nf5 and could find no defense for black. It probably took about 10 minutes. Too slow for the 20 minute games I normaly play.|
|May-30-07|| ||Crowaholic: Not too hard for a Wednesday.
I tried 31. Qh6 first, but couldn't find a nice way to deal with the pawn interference of ..e5 or ..f6. Then I had the idea of opening the g file and attacking with 32. Qg5+ and unstoppable mate, so 31. Nf5. Of course the sacrifice offer can be declined, but Black now has to deal with the knight fork threat. And the threat of playing Qh6 the next move with a now unstoppable mate because the knight conveniently covers g7, too!
So what options does Black still have? Basically only a counterattack could in general be of any use with respect to drawing or winning the game. But almost all of Black's pieces are in horrible places for an attack. And c1 is doubly covered, preventing 31. ..Qc1 with the threat of 32. ..Rxc1+, thus forcing the queen exchange, which would be favorable for Black, is not possible.
31. ..Nd2 can be countered with 32. Qh6 or 32. Nxe7+ Kf8 33. Nxc8 and now 33. ..Rxf1+ 34. Kg2 is not much use for Black. 34. ..Nc4 trying to at least recover the attacking pieces fails to Qh6+ and mate.
Black still has 31. ..Qxf5 stopping the mate for now, but that is tantamount to resignation. I looked at the solution and resign Black did.
|May-30-07|| ||YouRang: Got it in a minute or two. Of course, black has a screaming vulnerability at g7, so that's where I directed my attention. |
I wanted to play 31. Qh6, but the main problem is that ...f6 effectively shuts out the bishop. When I finally decided that I needed to attack from another angle, I looked at 31. Nf5, the rest of the line fell into place pretty nicely.
The knight is safe since 31...gxf5 leads to 32. Qh5+ & Qg7#. Since the knight can't be taken, the threat of Qh6 now has some teeth. It looks like black's only 'defense' is to trade his queen for my knight.
|May-30-07|| ||kevin86: I was wrong on two accounts:first I thought that 31 h6 was the strongest move in the deck. Then,I failed to see the quick knockout power of the text.|
Black's queen is under fire and white threatens 32 h6-NOW he does it- Mate is unavoidable. Of course, 31...gxf5 succuumbs to 32 g5+ f8 33 g7#
|May-30-07|| ||Draw Odds: <vibes43: Way easier than Mon or Tue.> Yes! And tomorrow somebody will say "This was easier than wednesdays" and so forth and so on, until finally on Sunday it will be the easiest problem possible.|
|May-30-07|| ||Justawoodpusher: Finally got it, but took me quite some time. If Adgestein calculates only half as fast as Magnus he probably saw this in seconds...|
|May-30-07|| ||jheiner: Good puzzle. The discussion about 30.Nf5 is interesting, and everyone is discussing 30. ... Rxf1+ 31. Kxf1 etc. What is the forcing sequence if White declines with 31.Kg2? Seems like White still has an overwhelming attack with 30.Nf5 Rxf1+ 31.Kg2 Bb5?! 32.Qh6 Qf8 33.Nxe7+ is forcing.|
|May-30-07|| ||ryanpd: Couldn't Adgestein have played this a move earlier?|
|May-30-07|| ||vibes43: <Draw Odds: <vibes43: Way easier than Mon or Tue.> Yes! And tomorrow somebody will say..... >|
Message boards are about expressing opinions and that was mine. The message also contained something else I felt to be of substance.
|May-30-07|| ||vibes43: <ryanpd: Couldn't Adgestein have played this a move earlier?> see <eblunt: No , 30. Nd3 was vital preparaton.>|
|May-30-07|| ||playground player: Hooray, finally solved one! Although it would've been a lot easier if it had been Black's turn to move...|
|May-30-07|| ||PAWNTOEFOUR: well i looked at it and thought about some way to break open black's position like nxg6.......however,shredder found the correct move before i could blink an eye......isn't this fun?|
|May-30-07|| ||fm avari viraf: At first glance, it seems that Black is having an overwhelming position with exchange-up & the threat of Qxh3. But after the brilliant move 30.Nf5 it turns out to be an illusion. The analysis show that Black can't survive against the multiple threats hence surrenders.|
|May-30-07|| ||Magic Castle: Nf5 is easy to find. However, the bone of contention here, which makes this puzzle difficult is Nd3. Is it really necessary? The immediate threat of Nf5 is the fork of the queen and the king. so that when the King or Queen moves or when the knight is captured the white Queen move is fatalto black. The suggested Kg2 after the sacrificed Rf1 is answered with Rf2. Hence. If the King captures, Qc2+ and the fork threat is avoided giving time to black to mobe the bishop from e8 to give king a escape. If Queen captures then black replies by capturing the Knight because white loses a tempo. These are not easy as someone has claimed.|
|May-30-07|| ||AlfieNoakes: Absolutely crushing move. Is this to contribute towards our frustration with Adams recent playing?|
|May-30-07|| ||YouRang: <fm avari viraf: At first glance, it seems that Black is having an overwhelming position with exchange-up & the threat of Qxh3.>|
Ooh! good point, Thanks.
I didn't even see the threat of ...Qxh3! So then, besides creating a killer attack, 31. Nf5! played an important defensive role: blocking the black queen!
(If I HAD seen ...Qxh3, I might have found the solution faster, i.e. find a good offensive move that also prevents ...Qxh3).
|May-30-07|| ||vibes43: Thanks <fm avari viraf:> and <YouRang>. My attempt to express that in the 4th message didn't come across right but blocking Qxf3 quickly led me to the solution. And the pin theme of Mon and Tue helped as well in that regard.|
|May-30-07|| ||wals: Never got near it. Went chasing butterflies again.|
|May-30-07|| ||soberknight: My first reaction was "how did this happen?" It's a wacky position. I saw that Nxg6 could be defended, but I didn't look much at Nf5 because I missed the point that after Qd7 (to stop the fork) Qh6 f6, it's still mate because the knight controls g7.|
|May-30-07|| ||iceman77: Double threat! Moving the queen will lead to mate two moves later.|
|Jan-24-08|| ||whiteshark: <30...Rd1???> was incredible.|
