  Once: Much as the same as <Dzechiel> and I suspect many others today. The two moves that jump out are 20. g6 and 20. Bxe6 - maybe I can play both? And then perhaps d5 and Nd4 to pile up on e6.

20. g6 appeals because it overworks the f7 pawn. After 20...Bxg6, we get to here:

And the f7 pawn is defending both the Bg6 and the e6 pawn. That's got to be worth something.

Then what? I guess we have to sac on e6 straight away before black can unwind his pieces. So that gives us 21. Bxe6

Now what? Black has lots of choices - 21...Kf8 (as played in the game), 21...Nxe6 (seems risky to walk into a pin), 21...Qe7.

I can't see a definite winning plan for white, but I do sort of like his position. When your opponent has an uncastled king and you have strongly placed pieces, you should think about saccing pawns to open up the position.

But calculate lines in this mess? Nope, not this soldier. It looks fun, but I am not convinced that it works.

Rewind back to our starting position and we see that white has better development. A quiet move like 20. Qd3 (Fritz's favourite after a few minutes thought) might actually be a more pragmatic choice.

<dzechiel: ... Once again, I think we need some adjective stronger than "insane".>

<tacticalmonster: ...I got to 20 g6 Bxg6 21 Bxe6 and after that I simply give up because there are too many variations.>

Too wise comments which just about sum up it for me too.

Apr-17-11  chessaddict25: i am wise enough to not even start calculating this mess...
Apr-17-11  luzhin: A further point in the game continuation is that if Black plays the very plausible 24...Bf5 then 25.e7+! Bxe7 26.Bh6+ Rxh6 27.Rg8 mate.
Apr-17-11  parmandil: As many others, I was immediately drawn to 20.g6, but after 20...Bxg6 I wanted to continue with 21.Rxg6 fxg6 22.Bxe6, which gives black some other defensive options than the game.

For practical purposes, I don't think it is necessary to see 22.d5 and 23.Qc4 in order to decide on 20.g6. Black's 21...Kf8 is just an attempt to get into a worse but perhaps holdable position. White can simply play 22.Bb3 and be satisfied with what he has accomplished in two short moves - ruining both the black pawn structure and king position. End games will be favorable to white, the pawn on h4 is weak, and there are still possibilities for an attack on the black king. Finding 23.d5 and 24.Qc4 is really a new puzzle, on how to exploit the clear white advantage in a direct attack.

The real question to resolve at move 20 is what to do if black does not cop out with 21...Kf8, but accepts the challenge with 21...Nxe6. What we want to do, of course, is 22.Rxg6 fxg6 23.Qxe6+ Kf8 (not 23...Be7 24.Qxf6), and again there is a complex position with several branches to consider. One possibility is 24.Qg4 g5 25.Nxg5 fg5 26.Qf5+ Kg7 27.Re6 Rh6 28.Bxg5 and white must be close to winning. But there might be better ways for black to put up a resistance here, and I don't feel very confident in these lines.

Apr-17-11  patzer2: For today's Sunday puzzle solution, the decoy sham sacrifice 20. g6!! Bxg6 sets up the demolition combination with 21. Bxe6! .

Basically, it's a sacrifice for positional advantage.

  Patriot: There is a principle that says when you are developed and your opponent's king is still in the center, find a way to tear it open.

I looked and just didn't see the tactical means to do so. I couldn't make 20.Bxe6 work. Then I looked at 20.gxf6, although it violates the above principle. I also looked at 20.g6 Bxg6 and it wasn't clear how to get thru.

Nice problem!

Apr-17-11  computer chess guy: Rybka 3 likes 21. .. ♕e7, considering this only for White.

  thegoodanarchist: legitimate Sunday puzzle! Very tough.

  lost in space: I saw the first few moves, especially due to the fact that 20.g6 "feels" right. But I was far sway from seeing a clear solution.

Only alternative I had a look at was 20. Bxe6.

Hoping for Monday

  Jimfromprovidence: I like the move put forth by <computer chess guy> 21...Qd7.

Now white has to spend a tempo to move the bishop on e6, then black forces a queen trade.

So, if 22 Bb3 Qxe2 23 Rxe2+, black connect his rooks with 23...Kd7.

  eternaloptimist: i missed it. this is the 1st time that i've missed a combo since before monday. i kept looking @ moves like 20.♗xe6 & 20.♙d5. i briefly looked @ the correct move 20.♙g6!!, but i didn't c much there when i was analyzing it. i overlooked the potential 4 this move. this is definitely an ingenious & long combo by bologan...a great job of calculation on his part.

  agb2002: From a Caro-Kann game, I think.

The material is even.

Black would probably consider the maneuver ... Nd5 and ... Nf4.

Three pieces converge on e6. This suggests 21.g6, to undermine e6, but after 21... Bxg6 22.Bxe6 Nxe6 23.Rxg6 fxg6 24.Qxe6+ Kf8 (24... Qe7 25.Qxd6; 24... Be7 25.Qxf6) White's attack seems to run out steam.

I don't know. I probably would try 21.g6 Bxg6 22.Rg4 to take the pawn on h4 and then push the h-pawn. If 22... f5 then 23.Rxg6 fxg6 24.Bxe6 looks promising (24... Nxe6 25.Qxe6+ Kf8 26.Qxg6 with multiple threats: 27.Bh6+, 27.Qxf5+, 27.Ng5, etc.).

  scormus: I never heard of the Scandinavian defense before, is it what we used to call Centre Counter Gambit and told our school team mates not to play. Looks like W gets one of those nice attacking positions typical against the Sicilian, only B doesnt get the open c-file
Apr-17-11  M.Hassan: "Insane" White to play 20.?
Sides are equal
I started with :
20.Bxe6 fxe6
21.Qxe6+ Nxe6
22.Rxe6 Kf8
And next 7 moves proves to me that Black can win!
23.Nxh5 fxg5
24.Bxg5 Qd7
25.Rf6+ Bf7
26.Ng6+ Kg7
27.Nxh8 Rxh8
28.Rxd6 Qxd6
29.Bf4+ Qg6
30.Rg6+ Kxg6
0-1
------------
Very difficult puzzle.I Could not solve it

  ZUGZWANG67: Missed it.
Apr-17-11  EXIDE: Too many combinations for me to figure out. On a gut level g6 was my choice, however I did not find any win for white. I am still not convinced that 21. Bxe6 wins for white. I have tried but have no answer for 21--,NxB. But that is me talking, an expert may be able to win.
Apr-17-11  stst: Quite many variations, one plausible line:
20.Qe4 (eying g6 wit P advance) Pxg5
21.Nxg5 Pf6 (Rg8 is also playable.)
22.Nxe6 Nxe6
23.Qxe6 Be7
24.Qxf6 Rf8
25.Qxf8 ... if (A) Kxf8 26.Rg8#
if (B) Kd7 26.Rxe7+ Qxe7
27.Qxa8 and Bk can resign when WQ can sweep the Q-side pawns.
Apr-17-11  sevenseaman: Was traveling yesterday and had a look at this Sunday puzzle.

Is a tough one and I can give myself no 'airs' of coming close. The feature common between the text solution and my mite is that e6 is the hinge.

Motoring around the state of Punjab I had a small break and I saw this beauty on the Sunday Chess page of the 'Times of India'. Try it.

White to play and win. Vishy did a 10 move#.

Apr-17-11  newton296: I didn't even try to unwind this mess!
Apr-18-11  patzer2: <Jimfromprovidence> and <computerchessguy> Looks like 21...Qd7! is a really good defensive move. Can't find any lasting advantage for White.

One possibility played out with Friz to a draw went:

21... Qe7! 22. Bb3 Qxe2 23. Rxe2+ Kd7 24. Bc2 Rag8 25. Rge1 Ne6 26. Bxg6 Rxg6 27. Re4 Rg2 28. R1e2 Ng5 29. Rxh4 Rxh4 30. Nxh4 Rh2 31. Be3 Nxh3 32. Nf5 Bc7 33. Rd2 Nf4 34. Kc2 Ke6 35. Ng7+ Kd7 36.

Na5 Bd4 68. Nc4 Rg1 69. Rxg1 Bxg1 =.

Apr-18-11  sevenseaman: I've had a deeper look at the Sunday puzzle and its text solution.

I am more inclined now to agree with <tacticalmonster> that it is a 'non-puzzle' and also with <dzechiel> feeling the need for a worser adjective than 'Insane' to classify the difficulty; Or even with <Once> concluding the 'mess' isn't worth unraveling.
