|May-27-07|| ||Skylark: I got it right, seeing the pattern immediately after Saturday's puzzle. If black accepts the piece, opening the e-file, the exchange sac on e7 is deadly. I'm actually pretty proud for getting this, although I only looked at possible defenses Bxd5, exd5 exd5 Bxd5, exd5 exd5 Be8 and Bd8 (this last I think is black's best defensive try). Hardly a "puzzle" though, more of an intuitive sacrifice.|
|May-27-07|| ||Gilmoy: I saw that cutting the Q from h5 was the key. 20.e5 does that, but it leaves the center closed. At the last instant I switched to 20.Nd5, just because it lets White open e, exposing threats on Be7. That gives White a way out of the annoying pin on h, e.g. Qe6 to trade his Bh5 for the Be7 with check.|
I missed Be8 -- I didn't think Black could tolerate leaving the P on d5 to support Qe6+. I also missed the clever final position -- White could sac twice, totalling a Rook, because he's threatening Qf7# and Qg6+ forking the loose Re8, so that R must move to stop the mate, and it has no such move -- hence White is getting his R back, and Black's exposed K can't survive a Q+R in the corner.
21.. Be8 drops a free pawn, cedes Qe6+, and cuts Black's Rs, forcing 24.. Kf8. That can't be Black's best defense. He must have missed the exchange sac.
|May-27-07|| ||psmith: A possible improvement in the game continuation is 23...Bxh5 (suggested by Fritz 5.32) for example|
23...Bxh5 24. Qe6 Qf2 25. Re1 Bg6 26. Qxd6 Kg8 27. Qe6+ Kf8 28. Qc6 Rd8 with good chances for equality.
|May-27-07|| ||jmi: Well, I didn't solve it... :(
That's because I encountered a problem with Black immediately giving back the piece with 20. Nd5 exd5 21 exd5 Bxd5! I saw the problem with Black is the a2-g7 diagonal and if Black can maintain control of this diagonal. It would be able to hold.
I puzzled for a moment if it's possible for a further piece sac with 22. Rxd5!! Qxd5 23. Bf3 Qc4! (and Black maintains control of the precious a2-g7 diagonal and stopping any Rooklifts because of White's possible back rank mate). 24. Bxa8 Rx8 and Black is a whole minor piece up but I would say the position is unclear.
Am I missing something?
|May-27-07|| ||sanyas: <jmi> 22.♖xd5 ♕xd5 23.♗f3 ♕c4 24.♗xa8 ♖xa8 does seem to be the correct line. Now 25.♕xh5+ ♔g8 26.♕g6+ ♔f8 27.♕h6+ ♔g8 28.♖xe7 does win back the piece, but after 28...♕f1+ 29.♕c1 ♕xg2 I can't see a winning line.|
|May-27-07|| ||Desperate Beginner: The time I've been closest to get a Sunday puzzle!
At first I check Bxh5 but with no cear perspectives for White.
Then I thought: why don't try to open a file to the King? The position of the Rooks seems to suggest it so I decded for Nd5, exd5 21 exd5 threating Bh5+.
I didn't get all the combination, but for now it's good this way!
|May-27-07|| ||tarek1: I got it wrong, choosing Rxd5.
Actually, it isn't a combination but a (correct) speculative piece sacrifice.
Instead of 23...Kxe7 (which allows the white queen to come on e6 with check) Black could have played 23...Bxh5! and now, on 24.Qe6, 24...Qf2, f7 is protected. Fritz rates the position at about +2, so no immediate, clear-cut win, but in the long run the white attack does look irresistible.
|May-27-07|| ||TrueBlue: 20.Nd5 exd5 21. exd5 Bxd5 (much stronger move I believe)
22. Rxd5 Qxd5 23. Bf3 Qd2 24. Qe6+ Kg6 25. Bxa8 Rxa8
26. Qe4+ Kh6 27. Qxe7
and white has small advantage. This is the line I got anyways.
|May-27-07|| ||blair45: I chose 20 e5, which was wrong. I found dzechiel's analysis most helpful, because he showed his thought process. Also Gilmoy's comments, because he explained the difference between cutting the Q from h5 with 20 e5 and 20 Nd5.|
|May-27-07|| ||nhat8121: i dont see it, what happen after Rh7 at the end?|
|May-27-07|| ||vangogh228: I'm pretty sure 27.... Rh7 leads to Black's demise.
28. Qg6+ Rg7 (if Kh8, it's mate for sure.)
29. Qxe8+ Kh7
30. Qh5+ Kg8
31. Re1 1-0.
I really haven't gone that deep into it, but that seems the most obvious. But what about 27.... Qa7. ? That seems a very good option for Black.
|May-27-07|| ||PAWNTOEFOUR: i'm in a state of shock....there was a N sac on d5 a few days ago...........i didn't see it then and i didn't see it now either....just out of curiousity,it took shredder 3:59 to find nd5|
|May-27-07|| ||fm avari viraf: It's a very instructive game so far the tactical aspect of the game is concerned. White exploits the vulnerable spots d5, e6 & h5 with tactical shot 20.Nd5 where Black is compelled to accept the sacrifice. But can Black survive after 23...Bxh5 [ 23... Rxh5 then 24.Rxe8+ Rxe8 & 25.Qxh5 is another line ] 24.Qe6 Rh6 not Bxd1 25.Qf7# 25.g4 Be8 forced 26.Re1 [or 26.Rf1 Qd4]?|
|May-27-07|| ||nimzo knight: <nhat> qg6+ wining the e8 rook (at least)|
|May-27-07|| ||nimzo knight: 27.. Qa7 again 28. Qg6+ Qg7 29. Qxe8+ Kh7 30. Qe4+ ... and white is all set to win with 2 extra pawn and exposed black king|
|May-27-07|| ||nimzo knight: sorry 30. Rf7 wins the queen. So white has job done here|
|May-27-07|| ||vesivialvy93: Missed !! too hard for me , but the kind of position Tal would have solved even in his bed 5 minutes before he died|
|May-27-07|| ||MJW 72: Black has no peices in danger. White's postion is not strong enough to push black off the borad. So, it is clear that this is a king hunt. The only realistic possiable way to get to the king sunday stlye is Nd5. I saw a few cute lines but there is no way I would play or see this in a real game.|
|May-27-07|| ||bogo78: < But can Black survive after 23...Bxh5[...]? > A nice deviation from the line you present is at 25 Rb7 Re8 26.Qd7. Black loses material to avoid mate.|
|May-27-07|| ||outplayer: I simply don't understand the need of 21...Be8.|
|May-27-07|| ||outplayer: That variation is terrible for black. That's why I prefer 5...e5.|
|May-27-07|| ||Marmot PFL: I was about 99% sure that Nd5 was the move, but thought just maybe after yesterday they might throw in Rd5 for variety. However both rooks turn out to be required. Probably black should have guarded e6 with Bd7 instead of Kf7, then he would still have 0-0-0.|
|May-27-07|| ||An Englishman: Good Evening: 6.5 out of 7, best weekly result in quite some time. Why 6.5? Because I didn't see all of the key moves in this Sunday puzzle. Anyone else looking forward to Monday?|
|May-28-07|| ||patzer2: The Sunday May 27th puzzle solution 20. Nd5!! initiates a demolition of pawn structure sacrfice designed to obliterate
Black's pawn cover and give White a crushing positional attacking advantage, as after the not-so-quiet but crushing move 27. Rf1!|
|May-29-07|| ||kevin86: Again,like yesterday,the intrusion of the knight at d5-leavs black in a tizzy. It then takes the powerful long rangs pieces to wrap it up very quickly.|
