- Don't trade active pieces
- Don't move a piece twice in the open stage, if you can't see another development move of minor pieces, think about the rooks or a piece improvement

- Don't be scared of O-O-O, White was definitly start the pawn storm on the king-side, so just easy queen-side castling and then to for the king-side, DON'T OVERCOMPLICATE THE THINKING!
- Don't waste a tempo on a move like a6 because of incoming knight, just develop if there are pieces still need to be developed. First, check first if the incoming really is dangerous, if not, continue with developmend

- check the pawn pushes twice, consider them and calculate them 2-3 moves ahead AT LEAST!

- exd5 was not good and advancing e5 and threat the knight on f6 would be much better. I need to be aware of these pawn pushes which brings also a threat.

- Qxd4 was just bad, can't say more about it. It led to tempo loses and my queen needed to move around too early. :/
- The blunder of the a rook was outcome of not developing my knight and instead losing a tempo with my Queen too early. I need to be aware of my rook on a, develop my knight on c asap.
