?? Using the King is the most common way to get out of check. But, best was 21.Qxd5! winning back a piece and half pinning your Bd7 With this move, you're going to win back a piece.

Maybe Bg4 was better?

No, lake-bay. This was the best move for the reason mentioned above. Nothings better then getting a piece, unless of course, it's mate.

21...Bg4 looks very strong. If Qxg4 then white loses the queen. Otherwise the white king is increasingly boxed in at the middle of the board.

? The problem is that it loses a pawn. Best, was 22...Bc6 which threatens 23...e3 preventing black from recapturing with the R en-prise which gives you a dangerous passed pawn that would be difficult to stop.

More importantly, moving the bishop on d7 would be a discovered check and picks up the white queen.

!!

As now, you have a winning attack. What should black do?

?? This was not it. Black had a crushing attack with 24...Bxh1! So, that wins a Rook instead.

This still allows you to get the R. Best for white was to move his Rook to h2 or h3.

Still missing 25...Bxh1

25...Bh6+ looks best. It gets the last piece involved in the hunt and checkmate cannot be more than a few moves away.

Overlooking that the Rook is still hanging.

26. Qg4 has some interesting counter-threats.

Better Bxh1

Not just better but best. However, the opportunity will still be there since it's check.

Actually, I think 26...Bxh1 might throw away the win! 27. Bxb5+ Bc6 (if Qxb5 then Qc8#) 28. Qc8+ Qd8 29. Bxc6+ Rxc6 30. Qxc6+ Qd7 31. Qa8+ Nb8 32. Qxb8+ Qd8 33. Qb5+ and perpetual check.

...Qc5#

I was going to suggest 27...Bxh1, but lake-bay is correct. What he suggested is checkmate. But, that move isn't far off, as your about to find it.

This time you found out. It was interesting, but there were a lot of blunders made by both sides. I suggest slowing down and taking more time here. In the aftermath, you found the right moves, aside from, missing the opportunity to capture the Rook. But, you found the mate. Still, I suggest taking a little more time. Just remember, as noted in the blog that self discipline is essential to becoming a better chess player. And, that comes in many form including taking time to figure out threats made by your opponent.
