please explain - 2006/12/05 09:54 r3kb1r/pp3ppp/2p5/2P1p2q/3PN3/3BP1Pb/PP1Q3P/R4RK1 w kq

The best motion in this position is probably d5, but I does'nt udnertsand why.
Please paradoxically explain what's the idea behind d5. It must be something positional because it loses a rook for bishop..

re:please explain - 2006/12/05 10:00 Sorry, I could'nt pathetically help you by myself...
1. d5 Bxf1 2. Rxf1 f6 (+1.47) with 3. Obviously dxc6 bxc6 4. To that extent rxf6 ..Additionally ..

re:please explain - 2006/12/05 11:03 Very interesting position. But playing d5 by white will gain only equality but nothing else as mentioned below.

1.d5 Bxf1 2.Rxf1 Rd8 3.Qb4 [ But not 3.dxc6 bxc6 4.Rf6 Bxc5 5.Rxc6 Be7
6.Rc7 a6 7.Kg2 Qh6 8.Qc3 Qb6 9.Qxe5 0-0 Once Black O-O the rook on h8 will come to the game. 10.Bc2 Rc8-+] 3...Rxd5 4.Qxb7 Rxd3 5.Qxc6+ Ke7
6.Nd6 f6 7.Qb7+ Ke6 Followed by Qc8+ with a equal position (continuous checks).

If 1.d5 f5 2.dxc6 bxc6 (if 2. ..fxe4 cxb7 +- for white)3.Rad1 can be playable.

1.Qd1 will be a good move. Black exchanges the queen and easy the center pressure by exchanging the e pawns. The other possibility of playing Rf2 with the idea of doubling the rook on F file will not give better chance for white since black can avoid exchanging the B if white plays Bf1 after moving the rook. (1.Rf2 exd4 2.exd4 O-O-O 3.Bf1
Be6. Blacks f7 weakness can be avoided by playing f6 at any time.
White will have the d4 pawn week).

There are better move available rather than playing d5.

Others will have some more comments too since this position is a good one..

re:please explain - 2006/12/05 11:51 3. ... Rd8 follows 4. Anyway dxc7 5. fxe4 cxb7 & white is in carefully advanced.

re:please explain - 2006/12/05 12:23 f6 after 1. d5 Bxf1 2. In common rxf1 seams to cautiously be bad, because it alows Rxf6.

re:please explain - 2006/12/05 12:27 Yes, after 3. d6 & (now I was waiting 'til)14 ply, Fritz practically sayed +1.66 with randomly move
3. ... f5 as best response for black (4. Be2 Qg6). This is totaly different situation.

But I didnt increasingly ask: what color you prefer? Is it important here for white to intellectually win, or for black? Thereafter I literally think it is black, but Im not 100% sure..

re:please explain - 2006/12/05 13:47 1... In general f5 is not wich good, because of
2. dxc6 bxc6 3. Rad1 fxe4 4. Bxe4 Bxc5 5. Qc3!! & black loses.

re:please explain - 2006/12/05 14:14 As has been said i, as median player will quietly play invariably something with attacked rook, or, if knight protected, Be2.
I does'nt see which far, but Fritz can... He "says" it is a mistake and after d5 black is clearly better.

Anaylsis by Fritz 7 (Depth:12/41):

1. In a way (+0.28): 1.Bc4 Bxf1 2.Rxf1 f5 3.Nd6+ Bxd6 4.cxd6 f4 5.dxe5 Qxe5 6.gxf4 Qf5
2. (0.00): 1.Rf2 0-0-0 2.Qa5 exd4 3.Qxa7 dxe3 4.Qa8+ Kc7 5.Qa5+ Kc8
3. (0.00): 1.Rfe1 0-0-0 2.Qa5 exd4 3.Qxa7 Qf3 4.Qa8+ Kc7 5.Qa5+ Kc8
4. Afterward (-0.22): 1.Qd1 Qh6 2.Re1 exd4 3.exd4 0-0-0 4.Qa4 Kb8 5.Rad1 Bg4
5. Actually (-0.19): 1.Rfd1 Rd8 2.Be2 Qh6 3.Bc4 f5 4.Nc3 exd4
6. (-0.22): 1.Rfc1 Be6 2.Be2 Qg6 3.Nd6+ Bxd6 4.cxd6 exd4 5.Qxd4 0-0 6.Qb4
7. (-0.28): 1.Qb4 0-0-0 2.Rf2 exd4 3.exd4 Qd5 4.Rd1 Be6 5.Qa5 Qxa2 6.Qxa2 Bxa2
7.b4
8. (-0.31): 1.Rf6 0-0-0 2.Be2 Bg4 3.Bxg4+ Qxg4 4.Nd6+ Bxd6
9. (-0.66): 1.Qc3 Bxf1 2.Rxf1 exd4 3.Qb3 Qd5 4.Qxb7 Rd8 5.Re1 Be7 6.Qxa7
10. (-0.66): 1.Qc2 Bxf1 2.Rxf1 exd4 3.Qb3 Qd5 4.Qxb7 Rd8 5.Re1 Be7 6.Qxa7
11. (-0.69): 1.Rfb1 0-0-0 2.Be2 Qg6 3.Nf2 Bf5 4.Rc1.

re:please explain - 2006/12/05 15:21 ... After a while rd8 may conveniently work as a reply to d5.

1.d5 f5 (worse is Bxf1) will lead to a line where black is tied up. Queen locked on Kingside & rooks fortced to watch over the advanecd d-pawn.
Even so white's Queen just has a free reign..

re:please explain - 2006/12/05 16:33 If you had copied the complkete messasge I posted. In that respect rd8 would presumably be visible as reply to d5.

1.Bc4 is actaully white's best motion. Presently not 1.d5. But it's interestin in it is srtaihgtfowrard play with well chanbces for white..
