 | | Open Defence: The move 13 Nd4 seems incorrect, why give black so much activity on the Queenside? This seems to be the position to avoid playing the White side of the Open Variation 13 a4 attacking the b5 pawn seems correct.
In fact in many games involving the Open Variation, a4 is the move that exposes Black's pawn weaknesses |

 | | al wazir: What was wrong with 30. Rxa2 ? If 30...bxa2 31. Ra1 Qb1, then 32. Rxa2 (32. Qxa2 Rc2+!). |
|
| Apr-17-10 | | Notagm: Al Wazir: Yes, but when the dust settles, White has Q, B, and 4 pawns vs Q, B and 2 pawns. |

| Apr-17-10 | | Gilmoy: <al wazir: 30.Rxa2 bxa2 31.Ra1> Rc2+ and Black goes straight for the K: 32.Kh1 Qxh3+ and 36..Qf2#
32.Kg1 Qxh3 33.Bf2 <33.Qe4 Re2> Bh4 <Δ#!> 34.Bxh4 Qxh4 <Δ#!> 35.Qf3 Rb2 and White must give his R. If White trades Qs instead (e.g. 35.Qd6+ Kg7 36.Qf6+), Black's K eats all three split pawns. 32.Kg3 Qd3 33.Qf3 <33.Kf3 Qe2+ 34.Kg3 Qh2+ 35.Kf3 Qxh3+ 36.Ke4 Qg2+  > Re2 34.B<any> Bh4+ Or, just given the game line, 31.Ra1 Rc3 <Δ 32.B* 35..Rg1#> is crushing enough. All those complications, plus the 295 point gap, must have been very intimidating for White OTB. |

| Apr-17-10 | | UnsoundHero: White must have either lost on time (clock), or resigned prematurely. Black has problems forcing a win after 33 Qa7 or Qb7. The threat of Qxe7+ is awkward to meet. |

The threat of [34.] Qxe7+ is awkward to meet.> <33.Qa7!> (placing the Queen on the same diagonal as the attacked e3-Bishop) does indeed seem to hold; for example: 33...Qf8 (if 33...Kf7? 34.Qxa2+ and White is winning because the capture on a2 comes with check; or 33...Qf7 34.d5=) 34.f5 Kh8 35. d5 and the position in complicated but probably balanced. <33.Qb7?> does not seem to work, however; for example: 33. ... Qf7 34.f5 Rxe3 35.f6+ Kg8 36.Ra1 Qe6–+ After 32.Qa8+ Black erred with 32. ... Kg7?. Better would have been 32...Rc8 . |

| | Peligroso Patzer: A propos my prior post and that of <UnsoundHero>, if it was a case of White resigning in a defensible position (rather than a loss on time), this, of course, makes the pun that much better. |

| Apr-17-10 | | Chessmensch: Deep Fritz 12 rates the final position at -3.60 with best play. Truly hopeless with all alternatives. It seems resigning was justifiable. |

Qa7!, which seems to be White's best defense? <Chessmensch: *** It seems resigning was justifiable.> Before seeing any concrete analysis, I would guess that it is sufficiently complex that the position was worth playing on, even if Deep Fritz 12 analyzes it as <  >. |

Qa7 Qf7 34. d5 Ra3 looks good for black. |

| Apr-17-10 | | dhotts: 24.Bxf5 seems like a great move that White missed. How does it evaluate? |

| Apr-17-10 | | Chess Network: @dhotts
Seems that the end result is a strong queen on f5. Can't be chased away and the e-pawn is of little danger to black. The white b-pawn will be subjected to attacked. That, combined with the potential to create a passed pawn w/c3 is tough to cope with. |

I don't have the benefit of Fritz here, but 33. Qa7 Qf7 34. d5 Ra3 looks good for black.> In your line, 35. Qd4 seems to hold things together for White, but that's just a quick observation with no computer checking. |

click for larger viewAnd now 34...Qc3! 35. Kxe2 Qxa1, winning. I doubt if the players saw this OTB, but I agree that white must have been daunted by all the threats. |
