|Aug-02-13|| ||al wazir: I missed 28. Rf6, the key move (and the first one that isn't obvious).|
What happens after 29...Kg8 ? If 30. Qg5+, then 30...Qg7, followed I suppose by 31. Qxg7+ Kxg7 32. Rxd6. White still wins the ♘ and is two ♙s up, but at least the ♕s are off the board and his attack is blunted.

White is down a pawn with pressure on the kingside. It does however seem that this pressure will definitely not lead to a forced mate, and only slight material gain: black still has enough defenders (3, 4 if you count one bishop move if black gets the time) to avoid greater peril.
White has to act, and the only moves that really come to mind are 26.Nxg6 and Nxf7. Nxg6 has the disadvantage of opening the g-file after 26.Nxg6 fxg6 27.Qxg6+ Qg7 28.Qxd6, but white will win another pawn and probably win. Another striking solution of this move might be 26....Kh7!. Yes, white did win his pawn back, destroyed a vital pawn in the black kingside and still has pressure, but how does this go on? Now fxg6 is an annoying threat, black will have the time to develop the bishop and get both rooks in. Rather, I'd probably go for:
<26.Nxf7> the biggest advantage of this move is that it creates Qxg6+, Qh8# and N/Qxd6. Black can't just move the king away, 26....Kh7 27.Nxd6 . Black has to capture, and both move fair bad: 26....Nxf7 27.Qxg6+ Kf8 (now Qg7 is impossible, and Kh8 28.Rxf7 1-0) 28.Rf6!. Rxf7+ is inferior, and the pressure will become too big after 29.Raf1.
<26....Qxf7> is the 'safe' option for black, white is now forced to content to a small material but very strong position. Or does he?
<27.Qxd6 Qg7> black would be wise to continue defending g6 at the moment.
<28.Rf6! > yeah, of course. If 28....Bf5 29.g4 .
I have to admit I did not initially saw Rf6 as a very strong candidate and only did during my analysis, but this is justified by the fact white wins his material back in any case. White is probably won after Qxc5 etc, but not as strong.
|Aug-02-13|| ||TheaN: Ah darn, <agb>.
On both 26.Nxf7 <B) 26... Qxf7 27.Qxd6 Qe6 28.Qxc5 seems to be advantageous for White.> and 26.Nxg6 <B) 27... Kh7 28.Nf4 looks good for White. For example 28... Qe7 29.Nxh5 Qe5 30.Rad1 Re6 31.Qxe5 Rxe5 32.Rxd6 Rxh5 33.Rxf7+ Kg8 34.Rc7 + -.> you destroyed my ideas, but the majority seems to be right.
I'm still not overly convinced that 26....Kh7 is not a good try by black though. Yes, 26.Nxf7 Qxf7 27.Qxd6 Qe6 did vaporize my ideas of destruction via Rf6, but I'd have to analyse 26.Nxg6 Kh7, especially ideas with Rg8 for black.
|Aug-02-13|| ||Bartimaeus: <TheaN> I had mentioned Kh7 as a possible option while declining the sac but on evaluation the continuation seems unpleasant for Black. Consider |
26. Nxg6 Kh7 27. Nf4 Be6 28. Nxh5 Rg8 (to prevent mate) 29. Qf4
White is threatening a Knight fork and will win the e-pawn by that threat and once the rooks get going, black will really be up against it. Overall, doesn't seem like a pleasant choice.
|Aug-02-13|| ||morfishine: Black's undeveloped WSB highlights th weakness in Black's position|
26.Nxg6 fxg6 27.Qxg6+ Kh8 28.Bxe4 (The Bishop is immune due to 28...Nxe4 29.Qxe8+ Kg7 30.Qxe4 or 28...Rxe4+ 29.Rf8#)
Frankly, I am unable to find a reasonable defense for Black since the WSB has no good square. For example: 28...Bxh3 29.Qxh5+ Kg7 30.Qh7#
PM: I examined 28.Rf6 (and 28.Rf4) but thought Black complicates with 28...Bf5
|Aug-02-13|| ||TheaN: <Bartimaeus> Hm. The biggest problem for black is that his king is so restricted. There might be some merit in Rg8-g6 first, get the bishop out and then doubling rooks?|
What I'm looking at is 26.Nxg6 Kh7 27.Nf4 Rg8 28.Nxh5 Rg6 29.Qf4 (I guess) Bf5 with the potential of Rag8 threatening Rxg3 and to move the knight of d6 for the queen's scope on the diagonal.
|Aug-02-13|| ||TheaN: Neh 30.g4 will probably work, and after 29....Be6 the e-pawn will fall. Does look playable though, at least there are some counterchances.|
|Aug-02-13|| ||LIFE Master AJ: 26.Nxg6 seems simple enough, in three moves, it sure appears that Black is busted.|
|Aug-02-13|| ||LIFE Master AJ: I did not think that 28...Bf5; was a good defense, did not seem to help Black.|
|Aug-02-13|| ||TheaN: Still not convinced.
I should really throw 26....Kh7 into analysis because it has way more merit than it's currently getting. Can someone bust:
<26.Nxg6 Kh7 27.Nf4 Rg8 28.Nxh5 Rg6 29.Qf4 f5!?>

Black ideas like Bd7 with Rag8 or Qe7 with Nxc4 seem decent. I.e 30.Rad1 Qe7 31.Rd5 Nxc4 with Be6.
|Aug-02-13|| ||morfishine: <TheaN> Ok, I'll take a stab: |
26.Nxg6 Kh7 27.Nf4 Rg8 <28.Nd5> (instead of 28.Nxh5)...Qd8 29.Bxe4+ Nxe4 30.Qxf7+ Rg7 31.Qxh5+ Kg8 32.Qe5 Rxg3 33.Ne7+ Kh7 34.Qxe4+
|Aug-02-13|| ||kevin86: I saw the knight sac but not much after that.|
|Aug-02-13|| ||patcheck: Black is one pawn up. Most of the difficulty of this puzzle could lay in the many possible answers for black (with few absolutely forced lines).|
26. Nxg6 fxg6 (forced to avoid 27. Qh8#) 27. Rad1 with many possible tries for black :
Qg7 (or h7) 28. Rxd6 and white will be a pawn up at least with a better position, for instance : 28.
Qxf6 29. Rfxf6 and white will win the g pawn (29.
g5 30. Rg6+ followed by 31. Rxg5, for example)
Re6 28. Qf8+ Kh7 29. Rxd6 and black is lost : 29.
Qxd6 30. Rf7# / 29.
Rxd6 30. Rf7+ Qxf7 31. Qxf7+ Kh8 (or Kh6) 32. Qf8+ (or Qf4+) followed by 33. Qxd6 / 29.
Bd7 30. Rf7# / 29.
Re7 30. Rd8 (for instance) and black has to lose more material to avoid 31. Qh8#
Be6 28. Rxd6 Qxd6 (what else?) 29. Qxg6+ Kh8 30. Qxh5+ Kg7 (or g8) 31. Qg5+ (better than Qg6) Kh8 (not 31.
Kh7 32. Bxe4+ Kh8 33. Qh6+ Kg8 34. Qh7#) 32. Rf6 and white as to give up its queen to avoid 33. Rh6#
Nf5 (with the threat 28.
Qxg3+ or Nxg3) 28. Qxg6+
Qg7 29. Qxe8+ Kh7 30. Qxh5+ Kg8 31. Rd8+ and black is lost
Kh8 29. Qxe8+ Kg7 [seems better than 29.
Kh7 30. Qxh5 (or 30. Rxf5 Bxf5 31. Qxa8 with advantage for white) Kg8 (31.
Nh6 32. Bxe4+ seems better for white / 31.
Kg7 32. Qg5+ protecting the g3 pawn and white should win easily although there are many options here to check : 32.
Kh7 / Kh8 / Kf7 / Kf8 )] 30. Rxf5 Bxf5 31. Qxa8 and white has a quality and a pawn up and should win relatively easily
Kf8 29. Bxe4!
Rxe4 30. Rxf5+Bxf5 (30.
Ke7 31. Qf7#) 31. Qxf5+ followed by 32. Qxe4 and white is two pawns up
Qg7 30. Bxf5+ and black is lost : 30.
Qxg6 31. Bxg6+ followed by Bxe8 and white is a rook and two pawns up / 30.
Bxf5 31. Rf5+ Kg8 (31.
Ke7 32. Qxg7+) 32. Qxh5 and white is three pawns up with a winning attack (threatening 33. Rg5 winning the queen)
Qf7 30. Bxf5 and white wins : 30.
Qxg6 31. Bxg6+ winning as seen in D3b / 30.
Kf7 31. Qxf7+ (for instance) Kxf7 32. Bxc8+ and white is at least a piece and two pawns up / 30.
Bxf5 31. Rxf5 winning the queen / 30.
Re6 31. Bxe6 Bxe6 and white wins
So, in conclusion: 26. Nxg6 fxg6 27. Rad1 seems to win in all lines. The best defense for black could be 27.
Qg7 (or maybe Qh7) although white stays in this line with a pawn up and a better position: 28. Rxd6 Qxf6 29. Rfxd6
Time to check
|Aug-02-13|| ||patcheck: I had considered : 26. Nxg6 fxg6 27. Qxg6+ but after 27. ... Qg7 28. Qxd6, I didn't think that white could win so easily.|
So, without having analysed well yet this continuation, I don't know for the moment which is the best continuation between this and the one I proposed.
|Aug-02-13|| ||patcheck: I just checked with fritz 12.
1) In the line I proposed: 26. Nxg6 fxg6 27. Rad1, Fritz suggests 27. ... Bf5 I hadn't considered.
2) In the line : 26. Nxg6 fxg6 27. Qxg6+ choosen by Fritz, it suggests 27. ... Qg7 28. Qxd6 Be6 and the solution does'nt seem so easy.

|Aug-02-13|| ||cyclon: A good puzzle. I only could find 26. Nxg6 ( on 26. Nxf7 Qxf7 [ 26. -Nxf7 27. Qxg6+ Kf8 28. Rxf7+ Qxf7 29. Rf1 Black is not immediately losing ] 27. Qxd6 Qg7 there's no straight fast winning line for White ) -26. -Kh7 ( there doesn't seem to be an alternative to this move - threat was 27. Qh8X ) 27. Nf4 and the threat is 28. Nxh5 intending 29. Qg7X. |
If 27. -Rg8 [ 27. -Re7? 28. Nd5 ], then 28. Rad1 and if f.e. -28. -Be6, then 29. Rxd6 followed by 30. Bxe4+ and Black's position collapses.
Black has plenty of other moves here like 27. -Bf5/-Nf5/-Qe7/-Nxc4 BUT none of these moves counters satisfactorily 28. Nxh5. Just one example in the case of 27. -Qe7 28. Nxh5 Qf8 ( 28. -Nf5 29. Rxf5 curfew ) 29. Qh4 is just too much for Black. In any case White's got pawn and good attacking position.
So, my 'propose' is 26. Nxg6 and cufflinks for Mr. Thomas in this good Puzzle EVEN if my solution is incorrect.
|Aug-02-13|| ||cyclon: I was blind here not to take into account fairly obvious choice 26. -fxg6 which still doesn't look very good for Black. White must regain material having still attack. I made same mistake here than Yesterday by omitting an important game-line.|
|Aug-02-13|| ||morfishine: While 28.Rf6 is the game continuation and wins, I don't see a good move for Black after 26.Nxg6 fxg6 27.Qxg6+ Kh8 <28.Bxe4>|

|Aug-02-13|| ||quinlan: Seems, 26. Nxf7 wins anyway, after: 26... Nxf7; 27. Qxg6+ Kf8; 28. Rxf7+ Qxf7; 29. Rf1, etc.|
