Here white did not have any trouble at all after your Update 33.Rd2!
Not even Stockfish could survive with black.
Evidently black is too cramped to defend its g-pawn and white's is too far advanced to draw without it.

[Add 32 to the move numbers, +/- is for the mover, not white.]

After 15.Rxg7 Rxb2 the material is even but black had to give up a piece to stop white's advanced g-pawn.

In terms of evaluation at the move 33 my line is a little bit down compared to TCEC game, in the terms of winning (f and h-files pawns cleared and g4 pawn advanced to g6) strongly ahead.
Parent - By MrKris (***) Date 2020-11-21 16:18
Nether of these took anywhere near the 176 moves from the original TCEC game after 33. Ng2:
https://tcec-chess.com/#div=sfb2&game=6&season=19

[Below add 32 to the move numbers, +/- is for the mover, not white.]


In the TCEC game Stockfish played 36.f6 after black's bishop retreated 34...Bg5-e7, and before its pawn advance g4-g5, winning in 176.

Here Cfish undid 33.Ng3 with 34.(2.) Ne3, Stockfish allowed 40.(8.)Nx(B)g5 hxg5, and Cfish played 50.(18.) f6 after it could invade with 54.(22.) Qf6.

> In terms of evaluation at the move 33 my line is a little bit down compared to TCEC game, in the terms of winning (f and h-files pawns cleared and g4 pawn advanced to g6) strongly ahead.


With TCEC's continuation through 33. Ng2 here Cfish took 59 more moves to win vs. Stockfish, TCEC equivalent move 92.

In my last post with your improvement through 33. Rd2! Cfish took only 32 more moves to win vs. Stockfish, TCEC equivalent move 64.

(Assuming the length of pointless resistance is irrelevant Cfish over +3.00:
here TCEC's 33. Ng2 at 13 more moves --vs.-- my last post your 33. Rd2 at only 8 more.)
