| prinsallan: 23... BxD5.
Why not go for the Knight at F3.
If white responds with QxF3, its open to
trade queens and black should win ?
If he takes back with GxF2, then the King is in jeopardy, or am I mistaken ? I would love drunkenknight over here right now. |

| offramp: I don't think that black has a great advantage after 23...Bxf3 24.Qxf3 Qxf3 25.gxf3 Kf8. I wonder if Rabinovitch lost this game on time, as black doesn't seem hopelessly lost in the final position. Also, does 35...Re3 36.Qb5 Rd8 win a piece? |
|
| Mar-29-05 |
| prinsallan: If I run the game in Chessmaster from 25. gxf3 ...
This is the result. Of course, since it looks like
Rabinovich indeed lost on time, this long game doesnt say much.Furtest down is the end position//

Ps. I think at least black would manage a draw after the trades. Ds |

Three comments:
1) You may not have the board set up right, because after 23...Bxf3 24.Qxf3 Qxf3 25.gxf3 c5 <26. d5> is not a legal move (White already has a pawn on d5). 2) Chess engines are generally good for studying relatively short lines with forcing tactical play. They are not known to be good at long-range consideration required for good play in this kind of endgame. So I don't think we can evaluate the position just by having <Chessmaster> play it out. 3) <I think at least black would manage a draw after the trades.> Agreed. |

| beatgiant: <offramp>
<does 35...Re3 36.Qb5 Rd8 win a piece?>There are other possible lines, e.g. 35...Re3 36. Re1. Did you find a win of a piece against all defenses? |
|
| Mar-29-05 |
| offramp: <beatgiant> I only looked at it quickly ; I saw that the pieces were 'skewered'. 36. Re1 Rd8 37.Rxe3 Qxe3 38.Kh2 Qxd3 39.Be5. How's that? |
|

 |
| Chessical: <Offramp> If 35...Re3 <36.Qb1> seems to hold the position for White, <36...Rd8> 37.Ne5 Rxe5 (37...Rxc3 38.Nc6) 38.Bxe5 Qxe5. |
|

| offramp: Qb1 does seem to do it. |
|
| Mar-30-05 |
| prinsallan: Thanks all for getting the discussion started.
I have no further comments at the moment,
but I agree. Qb1 looks solid. |
|
| Mar-30-05 |
| prinsallan: And yes Beatgiant.
I checked the game and I had missed the doubled pawn at D5 ^^ |
|
| Mar-30-05 |
| prinsallan: And the double pawn makes all the differance.
I let CM play CM again with the corect board and
this time White wins after a long endgame:

| beatgiant: <black doesn't seem hopelessly lost in the final position> If Black doesn't do something immediate, he's hopelessly lost: White has two pieces for a rook, a well-advanced passed c-pawn, the threat to aquire the a-pawn, and no counterplay is apparent. But if he does play 37...Rxa4, White can switch to a kingside attack. A sample is 37...Rxa4 38. Ne6! Qe7 39. Qc6 Ra2 40. Nxg7 Rf8 41. Nf5 Qe2 42. Re1 Qc2 42. Nxh6+ Kh7 43. Ng4, which is also hopeless for Black. Similarly, on 37...Rc4 38. Bxg7!, so that if 38...Kxg7 39. Ne6+, or 38...Qxg7 39. Nh5 Qg6 40. Nf6+ Kf8 41. Qd6+, or 38...f6 39. Qc6 Kxg7 40. Qxe8 Rxf4 41. Rd1, etc. |
