Comments and advice on a game that I played against 1.h4 I was playing a game with the Black pieces the other day against 1. h4. The reason why I wanna discuss this game with you is that during the game I always felt that my position is not stable, and at some point I was up by a pawn, but white had a lot of files to attack me and I needed to defend and it was uncomfortable. The engine gives an evaluation of -2.7 at the end but to me it was so unclear. I would really appreciate your feedback about the game in general in order for me to understand the position better so that next time I can evaluate the position better during the game and not be worried that I might be worse (although the engine says that I'm much better by -2.7). Moreover, I read somewhere that if your opponent plays 1.h4, then it's good to respond with 1...d5 opening the light-square bishop, and if your opponent plays 1.a4, then it's good to respond with 1...e5 opening the dark-square bishop. What do you think about this general tip? Also when your opponent plays 2. h5, do you prefer to play 2...h6, or do you continue occupying the center and fast development?

When playing through this game, at no time did I think that Black was losing.
I don't like 2...h6 myself. What are you doing? Preventing 3.h6? Why would you want to prevent that?
The other move I don't like is 12...O-O. The center is closed and it doesn't seem like your king is particularly unsafe in the middle or queenside. Your opponent has already spent two moves advancing the h-pawn; it's rather obvious that if you castle over there, they're going to play O-O-O and advance the g-pawn. Your h6 pawn makes a nice target. And it seems like it's difficult for your knights to get over to defend right away because of the e5 pawn.  I wouldn't say it's a bad move, but it's very foreseeable that it would lead to you being on the defensive.
