 | | kamalakanta: What a game. He is fearless, and extremely talented! Bronstein would have loved this game! |
|
| Jul-29-08 | | arifattar: Wasn't this a live game on chessgames? I remember <acirce>'s comment when White played d4. Something to the effect of "Dominguez is proving that 1.d4 is premature". Where are those pages of comments? |
|
| May-06-09 | | blacksburg: what's the deal with 7.Bf1 and 8.Bc4? |
|
May-06-09
 | | Phony Benoni: <blackburg> The idea of 7.Bf1 is that White isn't sure where it will be best posted. Once Black has played 7...e5, the bishop belongs on c4. Had it gone there on move 7, Black would have responded with ...e6. |
|
| May-06-09 | | blacksburg: oh ok that makes sense. |
|
| May-06-09 | | fref: Nice pun. |

 | | kevin86: White's the pawn march on to victory.
Funny,black can queen first but his extra rook gained is no match for the amigos. |

| May-06-09 | | Dillon: WOW wowowowow |

 | | Check It Out: This game through move 18 is so above my pay-scale. After that it seems a matter of end game technique (which would be above my pay-scale as well). I had to play through the opening at least three times just to get an idea of what was going on. The pun is funny, those three pawns were hilarious, scooting forward like that. |

| May-06-09 | | patzer2: Are two pawns worth a Bishop? Certainly, as in this game, when you get three practically unfettered center passed pawns as compensation that would seem to be the case. |
|
| May-06-09 | | patzer2: The most amazing combination in this game is the winning move 12...Nb6! that Black missed. It was first mentioned by <acirce> in 2004 on page one of the kibitzing here, and even chessgames.com did a bit of analysis with crafty at that time. The main possibilities seem to be 12... Nb6 13. Nxe5 (13. Qh5
Nf3+ 14. Qxf3 Nxc4 15. d3 Na5  ) 13... dxe5 14. Qh5+ Kd8 15. cxd4 Nxc4 . The combination seems to rely on two tactical themes -- deflection (removing the guard) and the trapped piece. The initial move of the combination, 12...Nb6, involves an attack to deflect the White Bishop as a defender of the Knight on f7. If White responds to 12...Nb6 with 13. Qh5, then the decoy sacrifice 13...Nf3+ sets up a trapped piece combination for the decisive capture of the threatened Knight. As in the game, White tries to get as much compensation as possible for the loss of the piece. However, in this 12...Nb6! line, it's not quite enough. |

 | | An Englishman: Good Evening: Not a great week for me. Rejected the game move--couldn't see how White wins after 17.Bf4,Bf7 or 17...Bg8; 18.Qh5+,Qf7. What did I miss *this* time? |

 | | Messiah: Very nice! I like this tactics very much. |

| | sackman: I found 16 d4 but there didn't seem to be a forcing line. Bonus puzzle can you find a sensible series of moves leading to the position at move 15?? What is blacks rook doing on h7? |
|
| Dec-06-20 | | morfishine: Regarding 'themes', 'Deflection' is completely different than 'Removing the guard' These are in no way, one and the same |

 | | agb2002: White has two pawns for a knight.
White has dxe6, g3, d4 and Bf1.
16.Bf1 looks too passive.
16.dxe6 bxc4 17.Qa4+ Ke7 18.Qxc4 Nxe6 and Black's extra piece will tell eventually. 16.g3 Nh3+ 17.Kg2 Bc8 looks winning for Black.
The only reasonable option seems to be 16.d4 to try to get some advantage from complex positions. For example, 16... bxc4 17.Bxf4 exf4 (17... Bf7 18.dxe5 and White's center is too dangerous) 18.dxe6 cxd4 (else d5 again with a powerful center) 19.Qh5+ Ke7 (19... Kd8 20.Qd5+ and 21.Qxa8) 20.Qf7+ Ke6 21.e7 Qxe7 22.Qd5+ and 23.Qa8. |

 | | perfidious: Would not have solved this if allotted a week for forty moves. |
|
| Dec-06-20 | | Brenin: I got 16 d4, mainly by eliminating all the alternatives (after yesterday's key move, I couldn't believe that the tame retreat 16 Bf1 would be the solution). I wasn't convinced that the line 16 ... cxd4 17 Bxf4 exf4 18 Bb3 Bf7 19 e5 would give White sufficient compensation for the piece, but then that's the difference between me and a GM. |
|
| Dec-06-20 | | RandomVisitor: After 15...b5 the machine likes 16.Bf1, but does not agree with the white move 20 as played.

| Dec-06-20 | | goodevans: <perfidious: Would not have solved this if allotted a week for forty moves.> Nor would I. Not properly anyway. But I did work out that it had to be 16.d4 as capturing the N seems the only way to get sufficient counterplay for the lost (sac'd?) piece. As <Brenin> suggests, there's really nothing else. I did see that black can't keep the extra piece with 16...Ng6 because of 17.dxe6 bxc4 18.Qh5 so there's really no avoiding 17.Bxf4. I must admit that I didn't give proper attention to 18...cxd4 (the only way I can see of preventing 19.d5) but I'd like to think I'd find the win OTB after 19.Qh5+ whatever black's response. <An Englishman: [...] What did I miss *this* time?> Did you miss that white - a piece down - was looking for compensation rather than a win? In the lines you gave white can play either 18.Bxe5 or 18.dxe5 and get just that. |
|
| Dec-06-20 | | goodevans: <RandomVisitor> You posted that just as I was composing my post so I see I was wrong to say "it had to be 16.d4". Understanding how 16.Bf1 gives good compensation for the piece is beyond me. At least I can see why 16.d4 is good. |
|
| Dec-06-20 | | RandomVisitor: <goodevans>The machine keeps changing its 'mind' on the scoring in the 16.d4 and 16.Bf1 lines. Note that in the 16.Bf1 line the machine eventually plays d4, so with the hanging pieces and sacrificed piece white first needs to untangle the ball of yarn. White must truly at this point have compensation for his piece, so he just goes about maneuver for future piece placement and threats.

| Dec-06-20 | | RandomVisitor: A final look. White has 16.d4 and delayed d4 (16.Bf1). White can delay d4 by first preventing black from exchanging two pieces (Bf1) but in the end our silicon monster 'thinks' this line is no better than playing d4 right away. White has compensation for his piece but apparently not a whole lot more...
