Answer 1

You don't seem to know the kind of plans that arise out of the way you played the opening. You lined up the Be3/Qd2 "gun" and then never fired it! You needed to play Bh6 at an early stage and look at the possibility of h4,h5 and maybe even sacrifice the exchange if conditions are right if he plays Nxh5.

"Winning" is another question, but you never really made him struggle and fight. Your hand was never anywhere near his windpipe!

25. Ne2 isn't great. I know you are already a pawn down at this stage, but leave the knight there to protect the pawns and instead look at Ra2-h2 to build a rook battery on the h file. It's a much quicker attempt to get at his exposed king while he is still a bit disorganized.

Answer 2

White winning at when? After a pointless 8. a4 Black has an upper hand. 15. g4 is a blunder, but White already is in a pretty bad shape (19. Nf3 might give White some fighting chances). At 20. ... Bg5 White may resign.

Answer 3

Win? What are you serious? This looks like a draw at best for white.

You would have had to play a lot better a lot earlier for white to have chance to win.

You were done when you lost that pawn and then let black move to f4 later

at 25 you should have left the horsie on c3 and got you other rook to the kingside asap by going ra2. after that depends what black did.
