opposite color bishop endgames with equal pawns are drawn 99% of the time
though 42. a5! would have won the game
Yes ! So I could win though... )
I felt it. But... as always... when only 3 minutes remained on the clock... I begin to hurry.
He meant 42...a5! could win for black. Sorry to disappoint.

Aron... people... I think that using the tablebase during a game in real time... is somehow unfair .
It gives you advantage before your opponent... does it?

I analized the game one more time.
No. He couldn't win by 42. a5.
I can sacrifice for this pawn... my Bishop.
Think you are a tempo short; however, you played the endgame well to ensure points. Good job

The line after 42...a5 provided in the game analysis in the original post (see analysis diagram above) is pretty straightforward and demonstrates that indeed black does win after 42...a5. Even though you (white) can sacrifice your bishop for black's a-pawn black wins the endgame, and as suggested in the above post, by just one tempo.

Oh... yes. Now I see it myself.
Thank you.
I don't respect computers / evaluation functions at all but there are people who use them to varying effect. Especially at very high depths, they are stronger than most humans.
I don't know what depth the post game computer runs, or even what engine they use but it might be worth acknowledging for players who are either generally weaker than it is, or who are lacking in one of the areas computers are typically decent in.
Of course. I recognize my mistake.
My intuition of the ending game position was wrong.
And I was wrong also when I declined the draw my opponent suggested to me in the end of the game.
Girl, see... I was too optimistic about the perspectives of my position. )
I noticed 3 key points in the game:
1. Your combination with 11. Nxg5, winning 2 pawns is great. After that, you had a chance to grab the b-file with like 16. Rb1 and be simply up a pawn and better. Intead, you gave him the b-file and then the c2 pawn for no reason.
2. You played 26. Kg2 and decided to inflitrate via Kh3-h4, but your king got trapped there. A better plan was to go Kf2-e3-f4, while putting your bishop somewhere else, like b4 and/or a5. That was very hopeful of winning.
3. You played 33. Rxc7, exchanging rooks. Giving up your good rook for your opponent's passive rook is insane. Moreover, the opposite color bishop endgame without the rooks is a hopeless draw. If anything, you are slightly worse because your king is so bad.

Not 16. Rb1?? due to 16...Qxg2+ 17. Qxg2 Rxg2+ 18. Kh1 Rg3+ (or R anywhere on g-file except g1) 19. Rf3 Bxf3#.

Thank you for your notes and attention. I understand my strategic mistake with Rooks exchange... It will be very useful for me to know this thing for the future...
And your plan with moving my King along the path f2-e3-f4 is very good ! )
This didn't come to my head while I was thinking how to infiltrate my King into the opponent's rows.
...but your first comment is too complex for my undertanding. (
How could I grab the unclosed b-file with my Rook ?
And I am like blind. I had to defend my g2 pawn with my Queen.
My opponent forced me to do that.
It seems like I screwed up the first point. Yes, white has to do something about g2 on move 16, and if 16. Rf2 Rb8 there is no Rb1 next move. Sorry about that.

Never mind. )
I myself... thought during the game... that I have advantage.
I thought that I made my left flank of the position solid.... and then I pushed ahead my pawn on the right flank... and the victory would fall in my hands.
Friends, lets learn how to play endgames rightly.
If there's only 7 pieces then, use tablebase: https://syzygy-tables.info/
Oh, Aron... The tablebase is a good thing.
