|Mar-29-06|| ||weary willy: cg.com 28 ....? for a Wednesday puzzle?|
|Feb-11-09|| ||gawain: I thought it might be 28...Nf4 first. Would that have worked?|
|Feb-11-09|| ||gawain: No, I see that Nf4 right away would have led to at best a perpetual check for Black.|
|Feb-11-09|| ||JG27Pyth: Was I supposed to visualize this all the way to 33.Ne2 -- ? Because that was a bit too deep for me. I did solve to 31.Re3|
|Feb-11-09|| ||DoubleCheck: 28. ...Rxg2+
29. Kxg2 Rg6+
Far as I got
I overlooked the 29. ...Ne4+!
Strong finish from black
|Feb-11-09|| ||fouard: 28...Rxg2+ begs to be considered. 29 Kxg2 or it's over in a big hurry. 29...Nf4+ 30 K moves Rd3 game over.|
|Feb-11-09|| ||cu8sfan: Is 29...g6+ also winning? I didn't see 29...f4, but the first move (28...xg2) simply was crying out to be played. I saw this in an instant.|
|Feb-11-09|| ||onesax: I don't think 29. ... Rg6+ is winning - white simply has too many pieces left to bring to defend. 30. Bg3 looks like the obvious move, if nothing else 30. Qg3 might even hold, and even moving the king and black is hard-pressed to prove anything.|
The key was that the rook on d6 blocks the bishop initially from returning to defend, so 29. ... Nf4+! and 30. ... Rd3! were the necessary moves in order to shutout both the bishop and the queen, and now the naked king has no defence.
I saw to 30. ... Rd3 in about 20 seconds and didn't analyse further, doubtless in an OTB game I would've sat and worked out the variations.
|Feb-11-09|| ||onesax: Funny that black tries to play an Albin Countergambit, plays the move e5 and never plays e6, and this gets classified as a French ... hehe :)|
|Feb-11-09|| ||zooter: 28...Rxg2+ is easy to find.
29.Kxg2 is forced to avoid mate
after that, I was initially looking at 29...Rg6+ but 30.Bg3 seems to hold well. However 29...Nf4+ seems to put white in tatters.
30.Kf3 is the only reasonable move here and after 30...Nd3+ it is all over for white...time to check how this went down
|Feb-11-09|| ||dzechiel: Black to move (28...?). Material even. "Medium/Easy."|
Black has many tempting combinations here, but he must be careful, as white has a few hidden resources.
For instance, black could try 28...Rxg2+ 29 Kxg2 Rg6+ only to be met by 30 Bg3 Nf4+ 31 Kg1 Qxh3 32 Qf3 and it looks like the threat is stopped.
And a blunder like 28...Qxh3?? is met immediately with 29 Qxh3 (remember to examine the whole board).
I think the line goes more like
28...Rxg2+ 29 Kxg2 Nf4+
In this move order, the rook remains on d6 (at least temporarily), blocking the retreat of the white bishop.
So, where does the white king go? He can move...
- 30 Kf3
- 30 Kg3
- 30 Kh2
- 30 Kh1
- 30 Kg1
- 30 Kf1
On most of these moves black can follow up with 30...Rd3. For instance
30 Kf1 Rd3 31 Qxd3
Moving the queen to safety (such has 31 Qc2) allows 31...Qxh3+ 32 Kg1 Qg2#.
31...Nxd3 32 Re8+ Kh7 33 Rc2 Qxh3+ 34 Ke2
and black has a queen and two pawn for two rooks. I suspect I overlooked an easier win here.
Similar lines for other white tries at move 30.
Time to check.
|Feb-11-09|| ||Utopian2020: 29 ...Ne4+ is correct 29...Rg6+ gets black nothing for the Rook sac. I didn't compute to mate, but I still believe I solved the puzzle.|
|Feb-11-09|| ||zb2cr: Hi <cu8sfan>,
As to whether 29. ... Rg6+ is winning, what happens after 30. Kf1? Black can't take the White KRP (the Queen guards it). 30. ... Rf6 looks too slow. 30. ... Nf4 is met with the simple 31. Bxf4, Qxf4 and to me it looks as though Black has nothing.
|Feb-11-09|| ||whiteshark: I missed ...Rd3 :(|
|Feb-11-09|| ||Utopian2020: Utopian2020: It seems that white would have been far better off having played 25. Nxd6 than 25. d5. White gave up a an important center pawn for a trivial a-file pawn. That's a move I might make.|
|Feb-11-09|| ||An Englishman: Good Evening: You have to see all three moves to claim full credit; nonetheless, it seemed pretty easy to me. Very nicely played, however.|
|Feb-11-09|| ||SamAtoms1980: Aargh! 28 ... Rxg2+ was the first thing I saw but I couldn't find the follow-up. So I went with 28 ... Nf4. After 29 Bxd6 Rxg2+ 30 Kh1 Black has to find 30 ... Nd3 to salvage a draw. Damn.|
|Feb-11-09|| ||al wazir: I found the same line <dzechiel> did, 28...Rxg2+ 29. Kxg2 Nf4+ 30. Kh2 (only it was at this point that I peeked, unlike <dzechiel>) Rd3 31. Qxd3 Nxd3 32. Re8+. This doesn't look very conclusive.|
|Feb-11-09|| ||Terry McCracken: 28..Rxg2+ 29. Kxg2..Nf4+ 30. Kh2..Rd3 31. Qxd3..Nxd3 32. Re8+..Kh7 33. Rf1.. Nxf2 34. Kg2..Qd7 35. Re3..Ne4 36. Rxe4..Qd5 37. Rff4..f5 38. Rxf5.. Qxe4+ 39. Rf3..g5 |
Maybe best...it will prolong White's game.
|Feb-11-09|| ||engineerX: funny that weary willy's opinion was heard after 3 years|
|Feb-11-09|| ||TheBish: Zhao Xue vs Bu Xiangzhi, 2005|
Black to move (28...?) "Medium/Easy"
After looking at 28...Nf4 for awhile (and finding it lacking after 29. Bxd6 Rxg2+ 30. Kf1), I found a move that works much better...
28...Rxg2+! 29. Kxg2 (forced, since 29. Kf1 Qxf2 mates while 29. Kh1 Rdg6 gives Black a strong attack with an extra pawn) Nf4+ 30. Kf1 Rd3! 31. Re8+ Kh7 and White must give up the queen to stave off mate, since 32. Qc2 Qxh3+ 33. Ke1 Qh1 is mate. Best is probably 28...Rxg2+ 29. Kxg2 Nf4+ 30. Kg1 Rd3 31. Bxf4 Rxb3 32. Bg3 Rxa3, where Black has a queen and two pawns for rook and knight, or better yet (for White) 28...Rxg2+ 29. Kh1, but Black should have an easy time here too.
|Feb-11-09|| ||Once: The basic motif here is a rook reloader that doesn't quite work.|

Black threatens 1. Rxg2+ Kxg2 2. Rg6+ with a strong attack. To get this to work, we need to deal with the two white defenders. The Qb3 covers the third rank and the Bb8 threatens both Bxd6 and Bg3, blocking the attack.

We need to block these defences. As with yesterday's puzzle, we do this by introducing new lines of attack.
1. Rxg2+ Kxg2 2. Nf4+ (blocks the bishop on b8 and brings a new piece into the action).
2...Kh2 3. Rd3. This removes the rook from the bishop's attack, blocks the third rank so that the white queen cannot defend, adds a new line of attack and threatens Qxh3.
A fun combination.
|Feb-11-09|| ||benjaminpugh: Did white just totally miss 33. Bxf4? What am I missing here? Two rooks and a bishop against a queen ain't too bad.|
|Feb-11-09|| ||benjaminpugh: Whoops, I didn't see 33 ...Qxh3. Still, a rook and a bishop against a queen is better than getting your rooks forked.|
|Feb-11-09|| ||Gilmoy: <onesax: ... black tries Albin Countergambit ... never plays e6 ... classified as a French ...>|
The pawn structure ends up as a French Exchange / Russian Panov by transposition. Black avoids typical Petroff lines (Bg4 Bd6 Nbd7 zzz) for the clever Nc6-b4-d5 tour, with a deep positional grip from the shelter of White's isolated Queen pawn. White loses a couple of tempi on his KB, lets Black centralize Rooks unopposed, gives him a free Rook lift, and then sends his only K-side defender to grub a pawn. Tsk.
