Honestly mate without a diagram or PGN moving thing you effort is wasted.
The lads have to go back to original game, copy it, paste it into a PGN
mover, then flick back to RHP and enter your line move by move to see
what you are saying.
That is too much to ask from the lads on here.
Chess players are famously lazy. That is why many Chess players wanting
to start a family marry pregnant women because they cannot be bothered
making love and would rather have someone else do it for them.
I'll do the cutting and pasting this time but it would have been easier if you
had done it because you had line already to go up.
Perhaps all you work and time will get a response.
(if the line is sound then I want ½ the credit.)
Personally I think the lad found his own answer when he said here:
45...g5 was better than 45....f5 the plan with g6 and then f5 creating two
connected passed pawns looks very good.
(or your computers....'Komodo' what is that? another chess program or your pet name for Fritz?)
Black to play.
(I would not class this an ending whilst both sides have two Rooks.)
