so 25...Nxa3 26.Bf2 Qa5:
[d]1r3rk1/5p2/2b1pPpR/q2pP1N1/p1pP4/npP5/1P2BB1P/3R3K w - - 2 25
So your turn?
Please note that I do not have to consider anything, as I know white's advantage in terms of eval after Qf6 is some 5-6 full pawns, meaning mate is close by. White just keeps the structure. Wherever the rabious black knight is sacrificed, a3,b4,e7,d6, white does not capture and simply increases threats on the king. If the knight is sacrificed on e4, after passing through d6, white captures it, and immediately after that closes the game again with Be3.
White combines the following threats in different lines:
- battery of rooks along the h file
- mating with Bh6-g7 and Rh8, with a single rook on the h file needed
- if the f8 rook goes away, f7 pawn falls and white f6 pawn decides the game; that is why SF outwardly strange moves like Rb7, to protect f7, before moving the f8 rook
- in a number of lines, checking with Rg7 first, so the king goes to h8, and then Rh3 is immediately lethal
- if h5 is played, then of course Bh5 wins easily
Still no answer?

Because if 26...Qa5!! holds then this position is busted and your confidence that this is so easy to win is wrong.
Furthermore, I, as an external observer, see that in the previous moves you were answering with SPECIFIC moves, but in this position with 25...Nxa3 26.Bf2 Qa5 you didn't answer like that, but only by giving a long theoretical answer but not the single MOVE that is needed to justify your "white is winning easily here".
Chess is so complex and amazing, that for example in this position there are countless variations that lead to amazingly pretty and tough for computers moves that lead to a win for white, but there may be ONE variation that black can force, that makes this a draw and spoill all the beauty from the position.
For now 26...Qa5 seems to hold and make this just a draw and mean all the testpositions were wrong(for example the sacrifice 22.Qf6+ or 19.Be1 etc) suggesting a white win.
