|Jan-16-08|| ||D.Observer: Can 29. d7 save the game?|
|Jan-16-08|| ||totalnewbie: <Open Defence> I'm inclined to agree about 14-17, it feels to me that black extended too far on the king-side without developing his queen's minor pieces. I think with a little more development (at least of the knight) then white would not have been able to simply run around rampant and unchecked down the center and on the kingside.|
After 19. ... O-O white has 2 rooks, bishop, queen, and knight on the king-side while black only has a rook and queen, not including the severely weakened pawns that fall shortly thereafter.
With so many threats to his ridiculously exposed king and with white able to so naturally penetrate black's defences with tempo, black's passed pawn is almost of no consequence to white, as black is not able to support it with anything.
|Jan-16-08|| ||arsen387: <D.Observer: Can 29...Rd7 save the game?> I think no, bcz that move allows 30.Qg5+ after which black loses a piece or even gets mated in several moves.|
|Jan-16-08|| ||jhoro: if you are like me, wondering what <Chep on his Shoulder> means, this may explain it
|Jan-16-08|| ||ivan999: chep in bulgarian could mean something really funny.|
|Jan-16-08|| ||kevin86: I enjoyed how black castled "out of habit". Certainly it wasn't to protect the king.|
The ending came on a focus attack on the rook at f8 after white gained total domination of black's home row.

|Jan-16-08|| ||parmetd: tolow47: Clearly to me blacks move 7.g5 was the killer for me it created the wholes that white exploited.|
incorrect in fact not playing g5 would be a mistake.
|Jan-16-08|| ||swordfish: I think 7...g5 is the book move in that variation of the Semi-Slav.|
|Jan-16-08|| ||Mulyahnto: It seems like 9...Bb4 is new (I think Bb7 is usually played here). In the end, white's position is just so much superior even though he's down 3 pawns.|
|Jan-16-08|| ||chaq: 20...Rd7?|
|Jan-16-08|| ||acirce: Well, 7..b5 transposes to the ultra-chaotic Botvinnik variation: 8.e5 g5 9.Nxg5 hxg5 10.Bxg5|
I think that these days theory considers it good for White, and indeed none of the top players seem very inclined to enter it with Black any more, while in the 90's it used to be hot.
Still, it is playable, of course. But other than that there's no real alternative to 7..g5.
|Jan-16-08|| ||DDR: Instead of 11...Bxc3 11...Nxg3 and black has a winning position.|
|Jan-16-08|| ||DDR: I am not saying that 11.Bxc3 is a mistake, but 11...Nxg3 is much more preferable from practical standpoint and still gives black winning advantage.|
|Jan-16-08|| ||D4n: This is a well played game, but I think black lost tempo on move 24...Be6. A well needed move to protect from mate, but losing a rook in return doesn't help much either...|
|Jan-16-08|| ||Ezzy: Black's queenside undeveloped for 20 moves - That is pretty rare.|
|Jan-16-08|| ||Xeeniner: <DDR> I don't know. 11. ...Nxg3 12. fxg3, potentially followed up by Bh4. White has a lot of pressure on the kingside, particularly on f7.|
|Jan-16-08|| ||Amarande: <DDR> I don't think 11 ... Nxg3 is winning; do you have analysis to justify this? I see 12 fxg3 and Black is in more trouble, as O-O is not an option due to the exposed King's flank, and now White has an open f-file in addition to all Black's other woes.|
Certainly it's miles better than 11 ... Bxc3?; Black's exchanges show an almost amateurish lack of understanding of the Pawn structure. Black has a weak color complex; he needs the dark squared Bishop sorely. He then proceeds to exchange his Knight, his only other developed piece, for White's *light* squared Bishop, the only reward being a mere Pawn (which only serves to open the position further while his King has no haven to speak of). After 11 ... Bxc3?, he certainly should have followed up by exchanging White's other Bishop instead, which would at least remove the strongest ravager of his weak squares.
14 ... h5 makes things worse (it further weakens the black squares) but by then Black is likely already losing, with no development and a King in the center in a semi-open position, plus the serious weak color complex. Weakness begets weakness (Black would possibly actually have been better off with 15 ... g4, completing the ruin of his black squares, rather than allowing White to open a line so readily).
By the 14th move I can't even see development or the return of some material saving Black. A plausible continuation where Black makes a belated effort at mobilizing his pieces could be: 14 ... Nd7 15 Nxc6 Qb6 16 Be5 f6 17 Bd6 Kf7 18 Qh5+ Kg7 19 d5 exd5 20 Rae1 Ne5 21 Nxe5 fxe5 (Qxd6 22 Qf7#) 22 Bxe5+ and Black is quite lost, as his King cannot survive on the open lines. Interesting variations occur at previous junctures, but the principle is the same; Black has no real chance to improve his position.
|Jan-16-08|| ||refutor: i imagine it won't be long before this line goes out of style for White and he returns to the Moscow Variation 6.Bxf6|
|Jan-16-08|| ||Jimfromprovidence: Black was not doomed early in the match. After 21…Qg5 (instead of Nd7) black is very much alive. |

The queen now has access to the back ranks and the knight (if it were at d7) does not block black’s e pawn protection by the bishop. If still 22 Rxe6, then this line leads to a complicated series of exchanges where black has an extra rook and pawn vs. the loss of a bishop and a knight.
I can’t find a win for white anywhere after 21…Qg5.
|Jan-17-08|| ||patzer2: Maybe it's not worth mentioning, but in instructing my Grandson I might mention that 18. Nf3! and the followup 18...Qg5 19. Qe5! is a nice example of combining
defending and attacking moves.|

But I do not find your answer <. . . [26...Kf7 what else? 27.h3 Qg5 ]> convincing.
|Jan-18-11|| ||rodchuck: <al wazir> 27. Qd8 threatening Nf8 followed by 28. Bd6 seems pretty solid|
