Why did I play Bh1?
Absolutely unexplainable move. I thought Qe4 was mating, but how could it?

As I mentioned at the start of the game, the right plan was a4.

After Rab6 Rd2 (the only move),

[d]8/1q4k1/1r4p1/pr1bPpPp/2pP1P2/2P3K1/3R3R/Q2B4 b - - 0 28

a4 was winning here

[d]8/1q4k1/1r4p1/1r1bPpPp/p1pP1P2/2P3K1/3R3R/Q2B4 w - - 0 29

I saw that move, thought to play it after Rd2, but still played Bh1??

The main reason SF holds until now is that I am playing like that all the game: I play one or 2 reasonable/good moves, and on the third move I make an outright mistake.
You can not win a game like that, even if the position is very favourable.

Louis, if you would like to reply to a4 instead on the above diagram, when you have time, I would be very happy.

The game is not competitive, I am making mistakes all the time, and we just want to see if black has sufficient advantage to win. For the time being we just saw black could have some advantage in certain lines.

Then we could go back to white's Qa1 instead of Qc1.

As soon as I see 150cps black advantage in some of the lines, that would do it.

Was it you just asking me if I was cheekily enough to go on posting in that thread?

And how do you come to the idea that after your 77...Rab6 instead of your 77...Bh1 78.Rd2 was the only move?

Luydmil that's becoming much too much of a farce to me, I'm finally cheekily enough to stop reading this nonsense now.

The only reason why I (and I guess some others too) still did, was to see, if and when you would finally come to your senses, but that might be simply not to be hoped for anymore.

Yeah, but I managed to make SF show consistent black advantage, when no one else on this forum would have even thought of it...

This is just a post-mortem, we are analysing the position, trying to see what its objective evaluation is.

And the main thing is that you learn a lot from analysis.

If I recall correctly, SF thought Bh1 was correct there. In any case, if you prefer Rab6 instead of Bh1, then SF seems to feel Rxa5 is safe and best. So you'd need to win from here before we consider any possibility of your playing a4 in reply to Rd2:

Sorry Louis.

It seems I am a bit tired and I mixed the positions.

We can continue in the mainline after Qa4

PS. I see how black gets small advantage after Bh1, but that might not be enough for a win.

Perhaps this is the place to stop for now, Lyudmil. We can always return to this position in the future, after you've had time to review all this analysis fully. Based on what I've seen (and I've seen SF's analysis for both White and Black for each position), I still believe the original position is a draw. But the position is demanding, and exacting play is required at each step. SF's Qc1 seems suboptimal; two later searches also led to Qa1 instead.

So let's give everyone a break. I'll spend some time testing recent SF patches that have dramatically improved search speed on my system.

OK, let's give everyone a break, as you suggest, and give you some time to test latest SF SMP patches. (you should never sleep here, just yield)

Whenever you would like to go back, just post your reply to Ra6, I still say black wins this.

Happy learning furthermore, Lyudmil.
Come back when you learned that the objective eval here is 0.00.
