|Feb-11-12|| ||MrSpock: 24. ... Nde5 25. g4 Bd7 25. Nf6+ Kh8 and Black is ok.|
|Feb-11-12|| ||Penguincw: Two knights always tricky. However, in this game, Jobava finds a way through.|
|Feb-11-12|| ||luzhin: But Black would definitely not be OK after 24...Nxe1: 25.Nf6+ Kh8 26.Nf7 mate|
|Feb-14-12|| ||ajile: This game shows why the very early 2..c5 can be dangerous for Black. White does not get this setup in the Modern Benoni since he delays ..c5 until after White plays Nf3 blocking the White f pawn from advancing.|

This isn't necessarily true, although many Benoni players (including Lev Psakhis) will play the Modern Benoni with the move order 1.d4 Nf6 2.c4 e6 3.Nf3/g3 c5 and go into the Nimzo after 3.Nc3 Bb4 to avoid the Taimanov below after 8.Bb5+ in the Benoni move order.
The variation reached in the game usually happens after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4 0-0 6.Nf3 c5
7.d5 e6 8.Be2 ed 9.cd Re8 (9...Bg4 is another common move) or sometimes after 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 ed 5.cd d6 6.e4 g6 7.f4 Bg7 8.Nf3 0-0 9.Be2 Re8. Mostly though in the second line White plays 8.Bb5+.
|Feb-14-12|| ||AylerKupp: <ajile> A slightly later ...c5 does not necessarily preclude an early f4 from White, it's the standard 4-pawns attack after, say, 1d4 Nf6 2.c4 e6 3.Nc3 c5 4.d5 exd5 5.cxd5 d6 6.e4 g6 7.f4. Although as <King Death> said, after 7...Bg7, the Taimanov attack with 8.Bb5+ is currently probably more common.|
I suppose Black could delay the 4-pawns attack further by 3...g6 4.e4 c5 but delaying ...c5 even further would probably take it out of Benoni lines and into King's Indian Yugoslav lines if Black avoids ...e6 and White fianchettos his LSB.
Speaking of the Benoni, I recently got the new book "The Modern Benoni" by Richard Palliser and it's very good and up to date, covering the lines with an early h3 by White (precluding ...Bg4), the Taimanov Attack, and the fianchetto variation very well. The chapters on the Taimanov are particularly interesting; unbalanced positions and some wild games as you may expect.
|Feb-14-12|| ||ajile: Thanks for the posts. I would think that there are probably other useful lines though that Black could transpose into if White delays Nf3 too long.|
If I were Black I would try to delay ..c5 as long as possible and only after White no longer has f4 as a possibility.
Another similar idea that is showcased today is the Veresov Attack.
1.d4 d5 2.Nc3
But in this case if Black is flexible and prepared he can instantly change the game with 2..f5 and play a Dutch Stonewall since White has blocked his c pawn from c4. (c4 is a key attacking move against the Stonewall Dutch setup)
So now after:
1.d4 d5 2.Nc3 f5 White must try to force the issue with moves like f3 and Bg5 to get in his thematic move e4. But it's likely since Black has deviated first he will be better prepared for the coming middlegame positions.
This is why I ask about the White openings where he delays Nf3. Are there lines that Black can transpose into that take advantage of this move order? (not necessarily Benoni)
|Feb-15-12|| ||luzhin: Pity Black didn't play on with 31...b2 after which we might have seen 32.Rf7!! Nxf7 33.Nf6+ Kh8 34.Nxf7 mate.|
