Yep, that MIGHT hold. Not sure, but here's the continuation I see:

1.Qxe5 fxe5 2.Rf1 Qe7 3.Bd1 b5 4.Bb3 Rc4 5.Kg2 {avoiding check on c5} a6 6.Bxc4 bxc4 7.b3 cxb3 8.axb3 Qe8 9.c4 Qe7


I will play 8...a5! and after 9.c4 Qa3!

draw!


Hi Karol,

I think you're right, and 8...a5! will draw! This more or less refutes the solution I had:

1. Qxe5 fxe5 2. Rf1 Rc8 3. Bd1 Rc4 4. Bb3 b5 5. Bxc4 bxc4 6. b4 * which is similar.

So I searched for an improvement and I think I found one!

1. Qxe5 fxe5 2. Rf1 Rc8 3. Bd1 Rc4 4. Bb3 b5 5. a4! a6 {seems forced} 6. Ba2!! Qe7 {lets try this} 7. b4! *

[D]6kr/4q2p/p3P1pB/1p2p3/PPr1P3/2P5/B6P/5RK1 b - b3 0 1
   ::    ::    :: BK BR
::    ::    BQ    :: BP
BP ::    :: WP :: BP WB
:: BP ::    BP    ::    
WP WP BR :: WP ::    ::
::    WP    ::    ::    
WB ::    ::    ::    WP
::    ::    :: WR WK    


Now white will capture the c4-rook with a winning Q-side pawn structure! Pushing the b-pawn will give an easy win!

Here is Toga 1.3 X4 analysis from the diagram (score relative to Toga - black here):

Code:
00:22:12.5   0,00   18   627003769   Qd8 Rf7 Qe8 Bxc4 bxc4 Rg7+ Kf8 Rc7+ Kg8 Rg7+

00:35:20.8   -3,05   20   1046837979   Qa7+ Kg2 Qg7 Bxg7 Kxg7 Bxc4 bxc4 Rf7+ Kh6 Rc7 Kg5 e7 Kf6 b5 ...

And CM9_R1 (score relative to white):

Code:
1:15   3/14   6.79   21533083   1...De8 2.Fxc4 bxc4 3.b5 axb5 4.axb5 Dd8 5.Rg2 Da8 6.Rg3 Da3...

8:29   4/15   3.53   137867222   1...Dd8 2.Fxc4 bxc4 3.Rg2 g5 4.b5 axb5 5.axb5 Da8 6.Rg3 Dc8 7.Tf5...

I don't think black can prevent this winning set-up for white. Any comments?
