Sorry Louis, will take some time, now I am busy with the no chance thread.

OK, just squeezed, Louis.
Possibly I will make a mistake, but just for the fun of continuing a bit the analysis: Bh6.

You can not concentrate on too many things, before I saw easy win for white in all lines, now white draws some...
I am sure the win is still there, but...

Let's leave this now. Here's SF's line. Not a good time---too many positions/threads to address at once.

Louis, I think we can take a leisurely approach.
Times are strenuous, so I gladly give you 40 days until your next move.
For the time being, in your main line, after Bd6 I deviate with Rb7 instead of Rbb6, hoping to claim an easy victory soon.

SF plays Rg1, and says Black already has a very small advantage:

Are you serious, what depth, 40 days seem like a very short time.
I will take my time anyway, as I am not as tireless as SF.
Will answer in due course, hopefully not very long from now.

I forgot Gaviota calculating for 3 days or so. I founds Rb3, but then it changes its mind. Score does not move much.
This seems a position in which black has advantage, but it is blockaded enough so there is not way for black to win. Most likely a draw.
