No chance

SF doesn't (yet) see a mate, though it shows White winning:

[EDIT] What about Qb4 in response to Bxc3?

Then 29.Bxb4 Rxb4 30.Rg1 wins.

Of course, but Lyudmil said Bxc3 was "mating".

Well it will mate eventually.
20 moves, 40, 60 moves some time it will....

Here is some analysis of the position(the PGN is meant to be read in Fritz/Chessbase GUI as it contains some symbols that i don't know if they appear in other GUI).

Starting after the Queen sacrifice with 22.Qf6+, it seems that black holds with 24...h5 instead of 24...h6 that seems to lead to a win for white.
So Qxf6 is not a good testposition after all as it leads to a draw most probably.
Any help to further improve the analysis and find things that i've missed, is welcomed.

Thanks for the analysis.

You do not stop amazing me.
On h5, white simply captures Bh5, and the game is over.

As I told you and Kim, white has at least some 5-6 full pawns advantage above in terms of evaluation at the root, and in such case you do not need to calculate anything - the win is simply there.

When 17.Bd2 is the root I am quite confident that after 17....Kg7 intending Rh8 white may be dreaming about 5-6 pawns advantage but I would prefer black after 17...Kg7 nonetheless

Thanks for the analysis.

You do not stop amazing me.
On h5, white simply captures Bh5, and the game is over.

As I told you and Kim, white has at least some 5-6 full pawns advantage above in terms of evaluation at the root, and in such case you do not need to calculate anything - the win is simply there.

When 17.Bd2 is the root I am quite confident that after 17....Kg7 intending Rh8 white may be dreaming about 5-6 pawns advantage but I would prefer black after 17...Kg7 nonetheless

Thanks for the interest, Ron.

The main test position is the one just before Qf6.

The line you are reffering to is way back.

But yes, Kg7, followed by Rh8, is the strongest defence, not certain how that ends, but it is the most reasonable move, to get rid of the bind on f6.

SF is afraid that in such case lines for attack are opened on the king side, whether it is right I am not fully certain, no time to check everything.

That is why I said in one of my messages that actually I got the initial position, after an artificial constructing, a bit not quite as I wanted it to: probably still winning, but with black being able to defend much much tougher.

But the main point was to show that such positions with a strong bind are losing for the bound side, and you have such a bind just before Qf6.

My point was not to win at any cost the game: you can always construct better positions with similar binds that engines still do not understand, and where even Kg7 and Rh8 will not be available.

[Lyudmil Tsvetkov]

On Nc3, white plays of course Bc3 a3 Bd2

[EDIT] What about Qb4 in response to Bxc3?

Qb4 does not quite look as a very promising defence, does it?

On Qb4, white has Nd2, followed by Nb1.

[Lyudmil Tsvetkov]

Will you stop that nonsense?

On Nc3, white plays of course Bc3 a3 Bd2

Why you can't talk like a civilized person? I'm trying to figure out if this is a valid testposition, so there is no need to speak so aggressively for no reason.

In our position yes you are right since 29...Qb4 30. Bh6 Rd8 31. Nh4! wins.

Sorry that you take it like that, George, I never really meant to be agressive.

Thanks for the interest in the position btw.

It is just that some of the lines you propose look a bit preposterous.

On Qb4, white should mate relatively quickly after Nd2, followed by Nb1.

Lyudmil, this position is very important for the future of chess engines:

At this time I work at some endgame problemas (Sting!)
In the closer future I will try to get this position (midle-game problems).
The problem of the horizon effect is far to leave it for an artifical intelligence, somethink it means
Many thanks for this position!

You are welcome, Marek.

Yeah, middlegame is always more important.

Leela finds the Qf6+!! move!!!!!! WTF??
INSTANTLY. By its eval!
Net 10815 to be accurate. I haven't tried others.
I guess this is because she knows that this specific pattern of encircling the King with these specific pieces works, i can't find other explanation.
she even finds the right continuation with Ng5!!
