| Sep-24-11 | | capafan: 13.O-O c5 14.Rae1 <a5> White has several options here (as suggested by Houdini 2.0): 15.Rd1; 15.h3; 15.b3 (maybe more) all essentially waiting moves that do not upset or prematurely clarify the balance in the center. If 15.Rd1 compare with variations where white plays 14.Rad1 (instead of 14.Rae1), e.g. Houdini_15a_x64: <depth=32> 1) +0.00 14.Rad1 cxd4 15.exd4 Rc8 16.Ng3 dxc4 17.Bf5 Nd5 18.Qd2 Qc7 19.Ne4 Ne7 20.Bh3 Rcd8 21.Bxe7 Rxe7 <DPLeo> ...this suggests that 15.Rd1 is not an optimal waiting move after 13...a5 for white and that 14...a5 may negate in some manner the 14.Rae1 option for white. If instead 15.h3, then 15...Ba6 and then compare with variations where black plays 14.Rae1 Ba6 14. Rae1 <Ba6> 15.cxd5 exd4 16.exd4 Nxd5 17.Bxd8 Nxc3 18.Bxa6 Nxe2 19.Rxe2 Raxd8 20.Rxe8 Rxe8 21.Bb5 Rd8 22.Bxd7 Rxd7 23.dxc5 bxc5 <imag> If, however, white chooses to clarify the center with 15.cxd5 or 15.dxe5, then compare with the following: [+0.00] d=24 14.cxd5 exd4 15.exd4 Nxd5 16.Bxd8 Nxc3 17.Nxc3 Rexd8 18.dxc5 Nxc5 19.Bc4 Rd4 20.Be2 Rd2 21.Rab1 Kf8 22.Rfd1 Rc2 23.Rdc1 Rd2 24.Rd1 Rc2 25.Rdc1 Rd2 26.Rd1 Rc2 27.Rdc1 Rd2 28.Rd1 Rc2 29.Rdc1 <imag> [+0.00] d=24 14.dxe5 Nxe5 15.Bxf6 Qxf6 16.cxd5 Bxd5 17.Bb5 Bc6 18.Bxc6 Qxc6 19.Rfd1 f6 20.Rd2 Rad8 21.Rad1 Rxd2 22.Rxd2 Re7 23.e4 Rd7 24.f4 Rxd2 25.Qxd2 Nc4 26.Qd3 b5 27.a4 Nxb2 28.axb5 Qb6 29.Qd7 <imag> Conclusion...not anything earth-shattering but a small refinement. Black may limit white's options to a small extent with ...a5 but the limitation is small; it is difficult to argue that ...a5 is significantly better than the straightforward ...Ba6 which leads to a draw. |

<JustWoodshifting: <AylerKupp> <So . . . what's the reasoning for thinking that 15.Bf5 would even be considered, much less played, by GMVA? > I don't agree with you. Just enter into Rybka, Houdini, or Critter our present position with <13.O-O c5 14.Rae1> and the same line comes up on all 3 engines: 14.-- Rc8 15.Bf5 cxd4. It comes up as the top line on all 3 engines.> Perhaps the resolution of this position is beyond the horizen of the engines. <AK>'s logic seems sound to me. Someone should chase this idea out 30 ply or so and see how the engines like it. Of course, the onus of proof is on the source of the idea, <AK> or someone who is charmed by it. |

| Sep-24-11 | | ajile: < Nickster: Looking for alternatives to 14... Rc8. Just looked at the AT and it's being filled up quite nicely. <YouRang> you have been quite busy. I was going to post lines on the <13...e4 14.fxe4 Nxe4 <15.Bxe4> Qxh4 16.Bxd5 Bxd5 17.cxd5 Nf6> line but you beat me to it. The lines you posted are exactly what I came up with. Interesting stuff but ultimately white keeps a small edge but it should be drawn.
The pawn push can be played one move later:
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 O-O 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.f3 h6 9.Bh4 d5 10.e3 Re8 11.Bd3 Nbd7 12.Ne2 e5 13.O-O c5 14.Rae1 e4> Analysis posted at the Tree. The line peters out into a draw with White a pawn up. But the pawn is isolated and White can't make any progress.

 | | kutztown46: I will be gone for several hours today. I may or may not be back in time for GMVA's move. If I am not, the delay will not be long. So if the new forum assignments are not immediately posted after the move, be patient. They will be posted soon after the move. |

 | | kamalakanta: I've got Deep Shredder 11 running on this, and on the variation 13.0-0 c5, the move 14.Rfe1 is in 5th place right now. 14.Rae1 is in 7th place! Other options it considers more logical are: 14.Rac1, 14.Rfd1, 14.b3 and 14.Qd2. I will leave it running all day on it and see what it comes up with... |

| Sep-24-11 | | whiteshark: <HeMateMe: We have him stumped. Either that, or his hard drive crashed.> I think this is the first crossroad for him and it's worth to take a deeper breath before he decides where to go. <13.0-0 or <13.cxd5>> that is a serious question. |

| Sep-24-11 | | Nickster: <ajile: Analysis posted at the Tree. The line peters out into a draw with White a pawn up. But the pawn is isolated and White can't make any progress.> I can't seem to find the line posted. Are you sure we're talking about the right position. It's move 14...e4 instead of 14... Rc8. 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Qc2 O-O 5.a3 Bxc3+ 6.Qxc3 b6 7.Bg5 Bb7 8.f3 h6 9.Bh4 d5 10.e3 Re8 11.Bd3 Nbd7 12.Ne2 e5 13.O-O c5 14.Rae1 e4

| | kamalakanta: It has moved up to 5th place...here's the thing: Shredder likes White's chances a little better in almost every main variation. |
|
Sep-24-11
| | kamalakanta: which means, with the two bishops, once the position starts opening up, we have to be very careful....particularly on the Kingside. |
|
Sep-24-11
| | kamalakanta: We have to meet White head on in the center. The line I like the most so far is, after 13.0-0 c5 14.Rae1 cxd4 15.exd4 Rc8 16.Bf5 g5! 17.Qd2 gxh4 18.Qxh6 Rc7 19.dxe5 Rxe5 and the position is pretty equal. |

I also agree that the team can not allow the bishop pair free reign in an open position. We have done a pretty good job so far weighing our options entering into this transition to the middlegame. I see no cause for alarm so long as we remain vigilant. |

| Sep-24-11 | | Nickster: Ok <ajile> just saw your post just below mine in the AT. You have 20.Bxf6 instead of my 20.dxc5. Either way black has not yet equalized. |

| Sep-24-11 | | thegoodanarchist: <Tabanus: Perhaps someone with a strong engine can check this line:> I'm on it! |
|
| Sep-24-11 | | imag: <Tabanus> This is a nice line, with potential winning chances. Of course we must remember that White still has the option of 19.Bxa6. Still, I believe we will see 13.cxd5 today. Rybka and Houdini main lines lead to positions with White being a pawn down. Although White has sufficient compensation, I don't think he will risk it. |
|
Sep-24-11
| | Tabanus: <imag> 13.0-0 c5 14.cxd5 is my guess. But let's see. |
|
| Sep-24-11 | | isemeria: I guess 13.0-0 c5. And then at least we have managed to give white a position where he can make an inaccurate move. :-) |
|
| Sep-24-11 | | YouRang: Putting my powers of intuition to work:
My guess is 13.O-O |
