Sven Schüle wrote:@Peter: in the g3 ... g2 system it seems to be crucial whether Black has one rook on g8 at the time of White's rook sac on g2. If he hasn't then Qf3 Kd7 Qxh5 seems to win because the White queen will capture a lot of black pawns by travelling via the 8th rank or h8-f6. Rg8 prevents this. In your newest line 5...Reg7 I hope White can create this winning position by zugzwang, e.g. Qe2-d1 or vice versa when Black has rooks on g8 and g4. Not sure, though, so far ...
I really wanted to leave this, but I had to repair my .pgn anyhow (you cannot store a wrong analysis of your own knowingly, you do store blunders without knowing so often enough
) and reading your own doubts about sure white win, I yet have to show the new version in case anybody still wants to try to get through it.
As a matter of fact I for myself cannot do so anymore without the feeling there might be blunders and or wrong evals and comments within still.
But then, it's not my fault, that you and others and not untill then me to found so many lines of doubt, so be it:

I could have let the old main variant on top as well, it's got a !? now, because as you say yourself, the doubling of the black Rooks on g-line should be even safer with one of them on 8th rank in case of having to open the fortress with ...g3 and then in the old main line with 5...Rg6 (now in braces and with !?-comment) the ...Reg7 back to doubling is the point too, that all made me advance instant 5...Reg7 to main line.
To make it easier for you to find the new line after 5...Rg6 (!?) here is a longer one as an example of follow- up moves after 6...Reg7 instead of ...g3 there, even if I think the final blunder came not until 7...g2 (?) in this one old line we had together as White win, 7...Reg7 there instead of ...g2 (?) still would have holded, I guess, have a look at this too, if you want, I hope, you'll find it, I marked it with the comment "Sven" at the beginning and at my end of it.
And then I followed your idea to force Black with Zugzwang in several lines to open up with ...g3 in the wrong moment and position, I don't think that works neither for White to succeed.
Not to give too many single lines that are in the .pgn too, here only the one after 5...Rg6 (!?) 6...Rge7 that I think to be a good one when Black has opened up the fortress with ...g3 and yet holds the draw:

BTW don't think I want to kill you by quantity instead of quality now, as a matter of fact I already had two newer .pgn- versions in the meantime, each a little bigger again then the one before, but after having changed copy-paste here twice already too, I spare some variants for my own still, so better take care!
