Thank you. But I think I missed a chance in the game.

Stockfish says (although only 10 mins. each :smile:) that not using the black pieces to move first lost 0.26 evaluation points:

It looks to be one of those games that engines score over optimistically for White. Despite Stockfish scoring over +2.5 for White, Komodo and Houdini were less optimistic scoring it more modestly. Although Black looked cramped there appeared to be sufficient defensive capability for Black especially once material was exchanged and its Queen became active.

Could only find one game with 10..Qc8. White lost after playing 11.Bg5. Suggests opponent came well prepared for this. How often is the Alekhine's Defence seen in correspondence chess?

I feel instead of 38. Nd6 my intuition was to kill the bishop but went on to play Nf7 where i feel was an inaccuracy.

You know a lot more about chess than I do, so take my advice with a teaspoon of salt.  Unless you have high blood pressure, in which case you had better skip it altogether.

I think the game was dead even from the beginning (despite the lingering pawn wood advantage) until move 50 where Qc7+ put your opponent into trouble (the computer did not see it yet, preferring Rf3):
8/6k1/6p1/4P3/2QPqn2/6R1/5K2/8 w - - acd 40; acs 233; bm Rf3; c3 "Qc7+"; ce 0; pm Rf3;

Here, 40 ply analysis shows that black is in difficulty:
8/2Q3k1/6p1/4P3/3Pqn2/6R1/5K2/8 b - - acd 40; acs 106; bm Kh6; c3 "Kh6"; ce -110; pm Kh6;

And here was your last chance for a big advantage, by moving Qc4, but Qc1 let him off the hook.
8/2Q5/6pk/4P3/3Pqn2/6R1/5K2/8 w - - acd 40; acs 162; bm Qc4; c3 "Qc1"; ce 149; pm Qc4;

Now, this analysis is only 40 plies deep and done by a rank amateur.  So you might investigate just for a laugh.

No win there either. Increasing depth with decreasing score ...

I had gone through this position many times. Didn't find anything to escape. had the black king and pawn 1 house back it would be a win. Interestingly Sf thinks optimistically its a win.
I feel i missed long before during the knight moves.
