This is JN - Carlos Garmendez Morelia 2008. Here I played a really clueless queen sac and lost later on time despite 30 seconds increment :wall: If I had played the correct queen sac 52.Qxg8+!? what would the result have been?

{I played the mistaken 52.Rg2?? Rh3+! 53.Ke2 Rxg4 54.Rxd8+ Kg7 55.Rxg4+ Kf7 56.Rd7+ Ke8 57.Rxh7 Qa6+ 58.Kf2 Qb6+ 59.Kg2 Rxh7 60.Bxh7 Qc6+ and incredibly with 30 sec. increment here i lost on time!!} 52.Qxg8+!? Kxg8 and what is the best line for both players from this position?

52.Qxg8+!? Kxg8 53.Rxd8+ Kf7 54.Rd7+ Ke8 55.Rxh7 would have been the logical end to the game. It turns out that if the black queen leaves the protection of Rh5 he will have queen against 2 rooks and bishop which must surely lose. However he has a study-like draw with perpetual check: 55...Rh3+ 56.Kg2 Rh2+ 57.Kg3 Rh3+ 58.Kg2 Rh2+ 59.Kg1 Rh1+! and white can't obtain more than a draw

Nice work Jesper, I tried to solve it but it was too hard for me.

Thanks Boris.
He, he, apparently it was also too hard for me in this OTB game because I played clueless there - however it had already been a pretty complicated game and I was short of time. It occurred to me walking home from the game that the trick with Rxh7 could work to for instance a won rook ending. My box then showed me 59...Rh1+! which is really why I show the position, quite a nice drawing trick.
