| Feb-11-17 | | Benzol: The ending of this game reminds me of the ending in this one Smyslov vs Botvinnik, 1941 |
|
| Feb-11-17 | | gofer: This one is way too easy for a <Very Difficult> Saturday. Black is already three pawns up and most of those are on their way to promotion, so all we need to do is avoid losing our queen for nothing and trade off a rook for another pawn and the bishop and we are on our way... <41 ... Rxe5>
<42 dxe5 Qxe5>
<43 Qxe5 Bxe5>

44 Rxb2 Bxc3! 
44 Rxe5 b1=Q+
<44 Rxg5+ ...>
White vacates the defence of the second rank in favour of taking the bishop, black has multiple choices; a) defend the bishop (temporarily) and distract the g rook for one move longer) or
b) give up the bishop (immediately) and get the king to relative safety, so that Rd1 can come into the action...

Black doesn't even have to try to defend the bishop! White
has such a weak back rank that the bishop isn't necessary! 44 ... Kh7

Lots of choices...

| Feb-11-17 | | mycroft2120: The real clue that everyone missed was that it was Averbakh -- the master of the endgame -- playing black! Knowing that, it was not hard to imagine that he would see the value of the unstoppable pawns so close to queening. |
|
| Feb-11-17 | | Cheapo by the Dozen: This is the sort of puzzle that a lot of us might get right over the board in a leap of Spielmannesque faith. What I didn't calculate all the way to was ... Rd1. |
|
| Feb-11-17 | | Whitehat1963: Wow! What a finish! To see that from so far back is impressive. |

Well, maybe not a direct quote, but close enough! ;-D |
|
| Feb-11-17 | | wtpy: I was looking at white resources if he didn't exchange. Didn't find many, not what you expect on Saturday. Game as played showed the pawns way more powerful. Black would win even without clever Rd1. |
|
| Feb-11-17 | | clement41: 27...Rxd3 and 28 Bxc5! would follow (I didn't find it, my engine did) (28 Qxc6?! would activate for free the Rb8 with immediate consequences e.g. 28...bc 29 Bxc5?! Rxb2 30 Reb1 (avoiding Ra2 as in 30 Rab1 Ra2) R3d2 |

| Feb-11-17 | | johngalt5579: I was totally outplayed , I thought it was white to win! |

| Feb-14-17 | | Moszkowski012273: Missing the super strong 28...f5 only to play the amazing ...Rd1 18 moves later. |

| Sep-01-17 | | Whitehat1963: Monday puzzle after 46...Rb5. |
|
| Feb-08-22 | | stridergene: Happy 100th Birthday Grandmaster Yuri Averbakh |
|
| Feb-12-22 | | newzild: Our hero the centurion might have missed the crushing 28...f5, 29...g4 idea, but his 46th move more than made up for it. |

46.? |
|
| Sep-20-24 | | King.Arthur.Brazil: The king doesn't see this as difficult: 41...Rxe5 42. dxe5 Qxe5 43. Qxe5 Bxe5 (44. Rxe5 b1=Q+ 45. Kh2 f6) or 44. Rxb2 Bxc3 45. Rbb1...
Maybe, best could be: 44. Rxg5+ Bg7 45. cxb4 c3 46. Rg2 Rb8 47. Rc2 Rxb... winning. |

 | | scormus: Difficult? Yes, I agree. But difficult in a somewhat unusual way. I wasn't sure between two easily seen moves which both turn out to be good for B. Only because it was a puzzle, my instinct went wih 41 ... Rxe5, but my head couldn't convince itself it would come out right, and so went with ... Qf5. I like to claim I'm in good company as SF16 picked 41 ... Qf5 (ca. +6.2 for B). When I forced ... Rxe5 it was better (ca. +7.2). Both after more than a minute of calculating) SF gave 45 Rgxe5 as an inaccuracy (h6 was better) basically becaue or 46 ... Rd1! A comment made years ago said finding that was the real puzzle. Why I this this is difficult in an unusual way. |

| Sep-20-24 | | mel gibson: < scormus: Difficult? Yes, I agree. But difficult in a somewhat unusual way.> When I see the way Stockfish pounds through billions of board positions I realise how feeble the human mind is
and it's surprising that the players often come up with the same line.
I think we do it by intuition. |

 | | al wazir: 44...Bg7 seems to win. How can white stop one or more of the black pawns from promoting? For example, the continuation could be 45. cxb4 c3 46. Rc5 Ra8 47. Rxc3 Ra1 48. Rb3 Rxe1+ 49. Kf2 b1=Q, or 45. Rb1 bxc3 46. Rg2 Rd2 47. Rxd2 cxd2 48. Kf1 c3 49. Ke2 c2. |
|
| Sep-20-24 | | Rosbach: This wins for Black: 41...Qxe5 42. Qxe5 Rxe5 43. dxe5 bxc3 |
|
| Sep-20-24 | | vajeer: With passed pawns and b�c3 also available, Rxe5 was just sceaming to be played. |

Here I chose 44...Bg7 the obvious 45. h6 doesn't work as black can play 45...bxc3
Now white has nothing better, if 46. Rxg7+ Kh8 black is rook down, but as they say pwan on seventh rank is equivalent to a rook, and black has two here!
click for larger viewIf white chooses 45. cxb4 then 46...c3 should keep the same threats open |

 | | MarcusBierce: I had the continuation correct, but finished with 46..Rd5. The advanced passers easily win |
