  kevin86: White wins by dominating from the eighth row with the rooks.
Aug-17-16  AlicesKnight: Nice example of utilising greater control of space. The triple N sacrifice is good - both other acceptances lead to immediate disaster. Haven't read all the kibitzing but I imagine someone has pointed to the parallel Alekhine vs Colle, 1925

  agb2002: White has a knight for a bishop and a pawn.

Black threatens Rxd2.

Black's back rank is weak. This suggests 30.Ng6+, to clear the e-file with tempo:

A) 30... fxg6 31.Rxd6

A.1) 31... Qxd6 32.Qxd6 wins (32... Rxd6 33.Re8#).

A.2) 31... Rxd6 32.Re8#.

A.3) 31... Qc8 32.Rxd8+ Qxd8 33.Qd4 Qb8 (33... Qxd4 34.Re8#; 33... Bd5 34.Re5 wins the bishop) 34.Qxa7 + - [R vs b] (34... Qxa7 35.Re8#).

A.4) 31... Rc8 32.Qf7 + - [R vs b+p] and several threats (Re8+, Rd7, Re7, Rxg6, etc.). For example, 32... Bc6 (32... Qxd6 33.Re8+ and mate in two) 33.Re7 Rg8 34.Rd8 wins.

A.5) 31... Rg8 32.Rxg6 hxg6 (else drop a pawn) 33.Rh3+ Qh5 34.Qg4 Rd8 (34... Qxh3 35.Qxh3#) 35.Rxh5+ gxh5 36.Qxh5+ Kg8 37.h4 + - [Q+P vs r+b].

B) 30... hxg6 31.Qh4+

B.1) 31... Qh5 32.Qxd8+ Rxd8 33.Rxd8+ Kh7 34.Ree8 g5 (34... Qg4 35.Rh8#; 34... Kh6 35.Rh8+ as in the line) 35.Rh8+ Kg6 36.Rxh5 Kxh5 37.Rxa8 + - [R vs p].

B.2) 31... Kg8 32.Qxd8+ Rxd8 33.Rxd8+ Kh7 34.Rh3+ Qh5 35.Rxh5+ gxh5 36.Rxa8 as above.

C) 30... Rxg6 31.Rxd8+ Qf8 32.Rxf8#.

D) 30... Kg8 31.Qxd6

D.1) 31... Qxd6 32.Rxd6 Rb8 (32... Rxd6 33.Re8#) 33.Ne7+ + - [R+N vs b+p].

D.2) 31... Rc8 32.Qxc5 wins (32... Rxc5 33.Rd(e)8#).

D.3) 31... Rxd6 32.Re8#.

  Geronimo: I was able to see to 31...h5, convinced it was sound but couldn't find the continuation, so no point for me today. What a nice puzzle and brilliant finishing tactic - there's a whole lot going on in here, and deeper minds than mine will probably crow "too easy for a Friday". Nevertheless, the combination of back rank mate threats and tempo-counting calculations make this instructive, and who in the end doesn't get satisfaction from beating a queen (plus bishop!) with two rooks? Thanks CG!

  gofer: I have seen this one before, that is the only explanation:

<Deja Vu>.

<30 Ng6+ ...>

30 ... Rxg3
31 Rxd8+ Qf8
32 Rxf8#

30 ... Kg8
31 Qxd6 Qxd6
32 Rxd6 Rb8 (hxg6/fxg6 Rxd8+ or Rxd6 Re8#)
33 Ne7+

White is a whole rook up.

30 ... fxg6
31 Qxd6 Qxd6
32 Rxd6 Rb8/Rg8 (Rxd6 Re8#)
33 Rde6

Again white is going to trade off into a being a whole rook up.

This is actually a better option than the line actually played ( from memory :-) )

<30 ... hxg6>
<31 Qh4+ Qh5>
<32 Qxd8+! Rxd8> <33 Rxd8+ Kh7>
<34 Ree8!!!>

~~~

My memory can't be as bad as I thought... ...five and half years!!!

Mar-31-17  Robespierre: When I arrived at move 34 my instinct was 34. Re h3 .... forcing 34 ... QxR followed by 35. gh3 This results in an endgame of R+5 pawns vs B+6 pawns which should be winnable by White.

Anyone else end up with this analysis?

Mar-31-17  redcircle: Nice combination.Almost got it but instead of 34.Ree8 I was considering 34.Rh3
Mar-31-17
Premium Chessgames Member
  Lambda: 34. Rh3 is the most obvious finish, since it allows you to have the exact same plan against 31... Qh5 and 31... Kg8, which makes reasoning the win quite efficient. 34. Ree8 is a nice refinement, but the position after 34. Rh3 looks like a pretty easy win to me, that bishop is going to be ineffective against the white rook.
Mar-31-17  Whitehat1963: What's wrong with 34. Rh3?

  Tiggler: <Robespierre> Yes, and I was kicking myself when I saw how much better was the move Shack played.

Think of it as an extra hour or so of life, after an immediate resignation, instead of a grind at the board. A lot could happen in that time, starting in the cocktail lounge in Bugojno.

Mar-31-17  wtpy: Tiggler, I like to think I would have seen Re8 at the board thus saving an hour of precious cocktail time.

Mar-31-17  saturn2: I looked at Ng6 long but could not spot the decisive skewer Rh3 (after Qxd8 etc)winning back the queen.

My move was <30 Rh3>

for example if 30..Rxd2 then 31 Rxh7 Kxh7 32 Qh4+

or 30..g6 31 Qh6

or 30 h6 31 Qxf7 looks good.

  Carlos0012358: 30......hxg6 is a huge blunder!!! 30.......fxg6 is correct. While it won't win a lost game it will make the game last much longer. Maybe it was lunch time and Timo wanted to end it quickly and go eat.

  swclark25: I also went with Ng6 and like <agb2002> comments about the weak back rank and the advantage of clearing the e-file. Also, agree with <Carlos0012358> that 30)...hxg6 was a mistake. I had Black responding with 30)...fxg6.
Mar-31-17  ozmikey: Saw the whole thing except I'd envisaged 34. Rh3 at the end, and I was thinking "exchange for a pawn - probably winning but there's bound to be something better". As indeed there was...

  TheBish: Mamedyarov vs A Timofeev, 2004

White to play (30.?) "Difficult"

Black is up a pawn, but his back rank is somewhat weakened, which Black can exploit tactically.

30. Ng6+! hxg6

Or 30...Rxg6? 31. Rxd8+, mating, or 30...fxg6 31. Qxd6! (Rxd6 wins more slowly) and now the weak back rank really shows, i.e. 31...Qxd6 32. Rxd6 Rc8 33. Re7 and it's just a matter of moves before Black must capitulate.

31. Qh4+ Qh5

Or 31...Kg8 32. Qxd8+! Rxd8 33. Rxd8+ Kh7 34. Rh3+ Qh5 35. Rxh5+ gxh5 36. Rxa8 with an easy win.

32. Qxd8+! Rxd8 33. Rxd8+ Kh7 34. Rh3 and after winning the queen back, White will be up an Exchange.

  TheBish: 34. Ree8! - nice finish. Missed that final move. White will end up a full rook ahead after winning the queen and bishop.

  morfishine: <sevenseaman> Sorry for the slow response to your comment: <morfishine Alekhine - Colle is a fine analogy you have dug up. Broadly the same way it works. I applied this principle. Please check my line in my first post, if there is a catch. To me it looked a parallel solution> Yes, this is the other solution with Black recapturing with the f-pawn
