If you'd like too, you could try to give in 2.(23.)Rb3 instead of Bd1 after 1...(22...) Rg8 after having finished MV- pondering.
Thanks for so much hardware- time.

Am stopping the search from root now, to take a look at lines proposed by others. At least I have a well-stocked hash table.

Hi Peter,
Here's what Cfish-dev shows for the position after Rg8 Rb3.

So far, Bd1 seems better for White than Rb3, according to Cfish ...

Thanks, Louis, 2...(23...) Rg7 might be better than the ...axb4 I had there till now, even if I'll have to look at this some closer still. Yet I already think I have to revise my judgement 22...g5 to be provable better than ...Rg8. Both moves might probably win, hard to tell, which one more clearly and more forcedly.
Peter.

Thanks to everyone for all the excellent help, especially since my Stockfish process crashed 17 hours into the analysis.
Interestingly, Sting may have found a new counter to Rg8 (answer with Kf1), though I am not sure you can trust it because Sting does not get very deep and the score was still falling. Still, it might be worth a deeper look:
