| bishop: Najdorf overlooks Stahlberg's startling 31.Bf7!! 31...Rxd2 of course will not do as it will be mate in 4. |

| slylonewolf: Of course it 'look' like the best move since White also threatens 31.Rf7, or 31.Bf7 depending where Black moves his bishop :) |

| jemelle: blacks game is lost either way. His backwards pawn is a liability. it can`t advance |

| sagahelten: There are no immidiate white threats after black plays 30. ... Qg7. A possible line could be: 30. ... Qg7 31. Qb1 Rf8 32. Qb5 Ra5 33. Qxb6 Bd8 34. Qc6 Bc6 35. Rd3 with a clear advantage for white. |

| kevin86: White springs his attack like a jack-in-the-box. Black must take the bishop and either way,his bishop is pinned. If 31... xf7 32  xd8!! |

| Calchexas: 31. Bf7!! I saw that coming, because, of course, I was looking for a way to threaten a mate. OTB, this was a brilliant and clinching move. However, I am simply elated that I saw this move, 32. Rxd8, AND 33. Qb7+! I'm definitely improving. Now just to start practicing my tactics OTB... And just how stupid did Najdorf think Stahlberg was, playing Bd4? If that was the best he had, why didn't he just resign? |

| patzer2: Rheinfeld's "1001 Winning Chess Sacrifices and Combinations" has today's (31. ?) problem identified as number 243 on page 55, under Chapter 3 on Double Attacks. After the "pin" and the "knight fork," the "double attack" is probably the next most common tactical theme. If 31...Rxd2 the pretty four move mate that Bishop referred to follows with 32. Qxg6+ Kf8 33. Qg8+ (preferring this move leading to mate over the tempting 33. Qxh6+ KxBf7 34. QxRd2 which only wins a couple of pawns) 33...Ke7 34. Qe8+ Kd6 35. Qe6#. If Black plays 31...Qxf7, White wins the exchange with 32. Rxd8 as the Black Bishop on f6 is pinned and cannot recapture without losing the Queen. |

| patzer2: The Opening may be of some minor theoretical importance as 10. Bg5 is the only move in the opening explorer where this move was played. However, it may not be any worse than the more popular 10. Qc2 (Black wins 54.5% and draws 27.3% of 22 games) or 10. f3 (Black wins one and draws four out of five games played). However, I suspect Najdorf's 12... Qe7?! is the opening error. Better perhaps was 12...Nxd3 13. Qxd3 Qe7 with the plan Najdorf envisioned (Kingside counterplay for Black against White's center and Queenside space advantage), but without the positional weaknesses created by the text move. |

| karlzen: This makes a Swede proud. |

| karlzen: Indeed Qe7 was a big positional mistake. d5-d6 is soon coming. 12...b6 is definitely an option as is patzer2's suggested Nxd3. Also interesting is 12...Nd7 when I believe white's best is Qc2 to control f5 and try to advance the c-pawn. Black's idea is always to play Qh4/e7 and f7-f5. |

| underrated: what about 31. Bc6, isnt that better???
looks like black must take rook then Be8 for white is a winner...right!?!? |
|
| Mar-13-04 |
| yoniker: underrated:
a) Black doesn't have to take the rook.
b) Maybe black may take the the rook as i can't see how white can win after for instant rxr be8 rd6 qxg6 kh8. |

| pogo5: <underrated> After 31.Bc6 , why take the rook?? 31...Qe7 followed maybe by ...Ra7 if White insists on attacking the d7 square, e.g. 31.Bc6 Qe7 32.Rfd3 Rxd3 33.Rxd3 Ra7. White looks certainly better but it not as clear cut as the game continuation, is it? |

| waddayaplay: Because of the badly placed rook and pawn @ b6 white plays as it were with an extra piece. |

| karlzen: <pogo5> in your line: 32...Rxd3? is a mistake. 32...Rd4 saves black's game. Instead 32.Rfd3? is replaced by 32.Rxd8 Qxd8 33.Rd3 Qg8 34.Rd7+ Kh8 35.Bd5 Qe8 36.Rf7 winning. 31...Rxd2 32.Be8 Rd6 33.Qxg6+ Kh8 34.Qxh6+ Kg8 35.Rxf6 Rxf6 36.Qxf6 and white has three pawns and bishop for rook plus the much better position. He will grab the b6-pawn too probably. Easy win. 33...Kf8: 34.Bb5 Ra8 35.Rxf6+ Rxf6 36.Qf6+ Kg8 37.Bc6 Rd8 38.Bd5+ Kh7 39.Be4+ Kg8 40.Qg6+ Qg7 41.Qxb6 again easily winning. Black can even try the sneaky 32...Rd1+ 33.Kg2 Rd6 to get Qb7+ and the white king in trouble, but still white will win thanks to his nice attacking pair and passed pawns on the kingside. So, <underrated> it may seem that you have stroken gold. The sad and not at all as fun, truth, is that black can play the unexpected 31...Raa8! when white will be limited to a big positional advantage. Thus 31.Bf7 is the best move, but it was very good of you to find Bc6-e8 in the first place. :) |
