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! *

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

Yes, you're right, Ba2 is winning even in line that I found. So the best line is: 1.Qxe5!!! fxe5 2.Rf1 Qe7 3.Bd1 Rc4 4.Bb3 b5 5.a4! a6 6.Ba2! and black is completely lost.

I remember seeing this same position on CCC a while back. I think White has a pretty easy time winning in a variety of ways. For example in the above line 1.Qxe5 fxe5 2.Rf1 Qe7 3.Bd1 Rc4 4.Bb3 b5 5.Bxc4 (instead of 5.a4) 5...bxc4 6.b3 should also win pretty easily for White. You can pretty much ignore all the program evaluations, since Black's rook and king are forever stuck in the corner, and likewise Black's queen mobility is severely hampered by the mate threat. Material is mostly irrelevant here. Computer's also have severe trouble due to the horizon effect, since it will take a little time for White's queenside pawns to get far enough down the board to create havoc. But when they do (and there is no way for Black to stop this) ..... game over.

Robin, do you have the entire game score for this position? I've tried to find it on the net but to no avail so far

Best ,
Terry
