  rhickma4: The line I came up with is:
20.Rxb5 cxb5 21.Nxd6+

If 21...Qxd6 22.Bxb5+
If 21...Bxd6 22.Bxb5
In both cases the final position has Q vs R&N.
Probably better for White, but not conclusively winning.

Aug-18-11  Patriot: Material: White has a piece for three pawns.

Threats: ...bxa4 or ...bxc4

This was very tough for me. I spent way more than a few minutes on this.

My main candidate started out as Ncxe5 and switched to Bxg6+ and started looking at Rxb5. I calculated the main line but it was still unclear to me. There is also a complication early on: 20.Rxb5 e4. And what's after 20.Rxb5 cxb5 21.Nxd6+ Kd8 22.Bxb5 Qe6?

I didn't have time to figure everything out but it is much more difficult than just saying "20.Rxb5 wins".

Aug-18-11  Fezzik: One thing that helped me to find today's solution was to do a quick material count before looking for the answer.

Anderssen's solution was brilliant, and he obviously saw it when he played 19.Rab1!

Aug-18-11  ProjectR: Well this is fairly difficult for a player of my ability but after looking for a while(initially looking at Bxg6+ ?? then bringing the knights into the attack blacks queen,only results in material loss!) i see that Rxb5 ..c/d white can check with a knight,and then there's pin after pin ! I can only see material gain and not all the way to mate
Aug-18-11  Marmot PFL: 20 Rxb5 cb5 21 nxd6+ Bxd6 22 Bxb5 is the main idea. Several variations could occur but the rook sac is not too hard to find as black forces matters with b5.
Aug-18-11  randyjohnson: The first move is quite intuitive Rxb5

but you have to see 20Rb7 and the weak d6 pawn for play this intuitive move.

20Rxb5...20e4!? 20Rb7! exd3 21Bxd6

  kevin86: An attacking game with an attacking opening.
Aug-18-11  Patriot: <randyjohnson> You're absolutely right that 20...e4 is a critical move to consider. I don't know if 21.Rb7 is best or if 21.Re1 is good.
Aug-18-11  gofer: <20 Rxb5! ...>

At this point, as black, I would be a little shell shocked! My opponent has given up a rook for a pawn. So would now be a RvN exchange down and two pawns down. So I would snap up the rook and lose in style...

<20 ... cxb5>
<21 Nxd6+ Bxd6>
<22 Bxb5 Bxa3>
<23 Bxd7+ Nxd7>
<24 Qxa3 ...>

click for larger view

The alternative of not snapping up the rook is more than a little bleak. (i.e. 21 Bxg6+ hxg6 is going to weaken our king side enough that castling becomes unwise.)

Perhaps black can try c5 trying to pin the rook, but this comes unstuck in a similar fashion!

<20 ... c5!?>
<21 Bxc5! dxc5>
<22 Bxg6+ hxg6>
<23 Nxe5 Bxe5>
<24 Nxe5 ...>

Suddenly the pin along a4-e8 diagonal has been reversed! Qe7 must move and provide white with a horribly strong discovered check!

<24 ... Qf5>
<25 Rb7 Kf8>
<26 Qc4 ...> mating

Time to check...

Aug-18-11  MiCrooks: I just wonder about that final position shown above...this game was played back in the days when losing your Queen was akin to losing the game. Material is fairly even here. This looks like the type of position where the Queen will be able to dominate, but I still wonder if some clever defense might still be mounted.

  Domdaniel: Oops. I made a big mistake here - not with the solution, because 20.Rxb5 is easy enough to see - but with the *players*. I thought White was the 20-21st century positional genius Ulf Andersson, not the legendary 19th century tactician with a similar name, Adolf Anderssen.

Luckily, the scenario works out much the same in both cases, as White is essentially refuting a flawed combination set in motion by Black. Either Adolf or Ulf could find the hole in an opponent's calculations.

Black has given up a piece for several pawns, expecting to regain it with the fork ...b5, emerging at least two pawns ahead. The problem is that Bxb5 will pin his Queen to his King, and the rest is working out the optimal move order. Rxb5 first, Nxd6+ second, and mayhem whether Black moves his King or not.

This type of carnage was natural to Adolf, but is a rarity in Ulf's games - mainly because his opponents were rarely dim enough to try anything on.

  Domdaniel: <chrisowen> You're almost lapsing into English. You might want to check if your obscurity filter is working properly, or to raise the threshold on your ambiguometer. Or maybe you need to renew your poetic license?

West Bishops.

Aug-18-11  Marmot PFL: <Dd> I didn't think Ulf would play the Evans, though here he plays the Moeller Attack - Ulf Andersson vs M Johansson, 1969
Aug-18-11  patzer2: Anderssen's 20. Rxb5!! combines a number of tactics into one neat combination.

First, it's a defensive combination that breaks the pawn double attack 19. b5, which Anderssen by the way teased his opponent into when he played 19. Rab1!

It also involves the demolition of pawn structure, decoy, deflection clearance, and pinning tactics. Not to mention threats against the exposed King and trapped Queen.

One might argue it also appears to have elements of a discovered attack with check and an in between move tactic, but that might be a slight stretch.

Here's some analysis with Fritz:

<20. Rxb5!!> Welcome into my parlor said the spider to the fly. I expected 19...b5 when I played 19. Rab1!

This move demolishes pawn structure, exposes the King & Queen to attack, and threatens a winning pin.

<20...cxb5 21. Nxd6+!> This clearance move prepares 22. Bxb5 and ends any hope of castling the helpless King to safety.


If 21... Bxd6, then 22. Bxb5 initiates a winning pin, when play might continue 22...Bxa3 23. Bxd7+ Nxd7 24. Rd1 Rd8 25. Qxa3 .

If 21... Qxd6, White initiates a winning attack with 22. Bxb5+ when play might continue 22... Ke7 23. Ng5 Nf4 (23...Kd8 24. Bxd6 Bxd6 25. Qa6 ) 24. Rd1 a6 25. Qc4 axb5 26. Qxc7+ Ke8 27. Qf7+ Kd8 28. Rxd6+ Kc8 29. Rc6+ Kd8 30. Qe7#.

<22. Bxb5 1-0>

Black's exposed King and Queen are helpless against White's mass of aggressively posted pieces. Black resigns in lieu of such possibilities as 22... Qe6 23. Ng5! Qd5 24. Ndf7+ Kc8 25. Ba6+ Kb8 26. Qb4+ Bb6 27. Qd6+ Bc7 28. Rb1+ Qb7 29. Rxb7+ Kc8 30. Qxc7#.

Aug-18-11  Memethecat: Got the answer up to 21NxD6+ but expexted 21...BxD6 then the BQ being lost to the pin. But if your opponent is gonna sac a R you know something is afoot. i like 20..D5 maybe followed by artificial castling KS. Much easier to sus this stuff out when you know there's an answer and no bloody clock ticking away.
Aug-18-11  beenthere240: I am was intrigued by david2009's suggestion of 20....Nf4, which threatens to exchange off the LSB. It has the advantage of making white recalculate, since most of his work would have probably been spent on the ramifications of accepting the rook on b5. The more I look at it though, the less I like it. 21. Rb7 looks pretty powerful.
Aug-18-11  BOSTER: <dzechiel> <It took me a minute to work out combo 20.Rxb5>.

You 'd better spend couple minutes to discover that after 20...o-o white <will be lucky to survive>.

Aug-18-11  CHESSTTCAMPS: In this tactically rich middlegame position, white has a bishop for three pawns, but faces the prospective loss of the knight on c4 to the pawn fork. White can get a pawn back with 20.Bxg6+(??) hg 21.Qc2 bxc4 22.Qxg6+, but 22... Qf7 23.Qxf7+ Kxf7 24.Rb7 Ne8 (defending 25.Bxd6) does not look promising for white. After looking at this, I realized that white can not retreat and need not retreat. As usual, active pieces can be put to good use against a king caught in the middle.

20.Rxb5! (Candidate #2) knocks out the lead pawn of black's queenside pawn roller, keeps the valuable LSB, and exploits the lineup of Qd7-Ke8:

A) 20... cxb5 21.Nxd6+! (the point) Bxd6 22.Bxb5 Bxa3 23.Bxd7+ Nxd7 24.Qxa3 leaves white with Q for R+N and a won position because the BK can't castle easily and black a-pawn and e-pawn are weak.

A.1) 21... Qxd6 22.Bxb5+ K-moves/Nd7 23.Bxd6 wins.

A.2) 21... Kd8 22.Bxb5 Qe6 (Qc8 24.Nf7 is a cute helpmate) 23.Bc4 Qd7 24.Nf7+ Kc8 (Ke8 25.Bb5 wins) 25.Ba6+ Kb8 26.Rb1+ Bb6 27.Bd6+ wins the Q.

A.3) 21... Ke7 22.Nxb5+ (Bxb5 is also winning) Kd8 (Kf7 23.Ng5+ Kg8 24.Bc4+ Nd5 25.Nxc7! Qxa4 26.Bxd5#) 23.Rd1 wins queen with ongoing attack.

B) 20... e4 21.Rb7! exf3 (planning Qg4) 22.Nxd6+! Kd8 23.Bf5 Qe7 24.Rd1 Bxd6 25.Rxd6+ Qxd6 26.Bxd6 wins.

B.1) 21... exd3 22.Bxd6! Nd5 23.Re1+ Kd8 (Kf7 24.Nfe5+ wins BQ) 24.Nfe5! Nxe5 25.Nxe5 d2 26.Rd1 Qxd6 27.Nf7+ Kd7 28.Nxd6 Kxd6 29.Rxd2 leaves white with a Q vs. N+B and the black king very exposed in the middle.

B.1.a) 22... Bxd6 23.Rxd7 Kxd7 24.Rd1 followed by Rxd3 with Q for R+N and pressure on the K.

B.1.b) 22... Rc8 23.Qxa7 Nd5 24.Nfe5 wins the Q as in the main line.

B.2) 22... Bxd6 23.Rxd7 Kxd7 24.Bf5+ K moves 25.Qxc6 picks the black position apart.

C) 20... d5 21.Rb7 dc 22.Bxc4 regains 2 pawns, traps king in center, and threatens 23.Rd1 (removing Q from defense of c-pawn).

No time for further analysis. Time for review.

Aug-18-11  Dr. J: Here is some admittedly non-exhaustive analysis that is enough to convince me that White is winning after 20 Qxb5:

(A) 20...cxb5 21 Nxd6+ is the game continuation.

(B) 20...0-0 <jheiner> 21 Rb7 e5 22 Bxd6 Rfc7 23 Bxc7 exd3 (or 23...exf3 24 Bxg6, or 23...Rxc7 24 Nfe5, or 23...Qxd3 24 Nfe5) 24 Nfe5 Nxe5 25 Nxe5 Qe7 26 Qb3+. White is ahead at least a piece for a pawn.

(C) 20...e4 <Patriot> 21 Rb7 and I do not see anything better for Black than 21...0-0, transposing to line (B). (Certainly not 21...0-0-0 22 Nxd6+.)

(D) 20...Nf4 <David2009/CraftyEGT> 21 Rxe5+! (Let me brag, please: I saw this pretty much right away.) I did not systematically analyze this, but play against the EGT continued as follows: 21...dxe5 22 Ncxe5 Bxe5 23 Nxe5 Qd3 24 Bc4 Ne2+ 25 Kh1 Nc3 26 Qa6 Nfd5 27 Re1 Nc7 (may be a mistake) 28 Qg7 (28 Bxe6 Nxe6 29 Bc4 also wins) N3d5 29 Bxd5 (29 Nd3 also wins) and White now wins everything in sight.

Lots of material there for some kind person to refute!

Aug-18-11  Dr. J: <CHESSTTCAMPS> and I were writing our posts at the same time, but it looks like they complement each other very nicely. Despite the length, very little overlap!
Aug-18-11  Patriot: <BOSTER> I don't think <dzechiel> meant it took only one minute to see the combination. He looked at it for a while and after seeing the queen and king alignment it took a minute to see the combination. But I think you are right that there is still more to calculate. I didn't even consider 20...O-O as a possibility but I did consider 20...e4 which is another critical move.

<Dr. J> Thanks! You are correct. After 20...e4, 21.Rb7 is the key which <randyjohnson> also pointed out. Many did not consider this and I don't think it can be ignored because it is an attempt at counter-play.

Aug-18-11  CHESSTTCAMPS: I didn't consider the Crafty EGT 20... Nf4 in my analysis, but I managed to find the right continuation 21.Rxe5+! amd won without difficulty on the first attempt - rather unusual for me in complex positions. I see that <Dr.J> did the same.

  Domdaniel: <Marmot> Thanks for pointing out that fascinating game from young Ulf. I like the way it goes on ... and on ... and on. Like a sort of tactical grind.
