I Really Want to Get Better!

I had a look at this game:

1. On move 2, you developed your knight to h6. This is usually a bad tactic, knights should normally be developed towards the centre, so Nf6 would have been a better move.

2. On move 3, you brought your queen out early, hoping to checkmate your opponent on f2. Your opponent of course defended against this threat, as they generally will. It is not generally good to bring your queen out early.

3. You left a bishop attacked although you could win it straight back with a fork.

4. Your opponent left a rook attacked on a1 but you preferred to capture the knight. As it is, if you capture the rook, your opponent may make things difficult with Nc3 which has the queen trapped in there. Even if they can't win the queen, the fact it is inactive on a1 may turn out bad for you

5. On a number of occasions you gave away pawns for free. Maybe pawns do not feel that important to you, but they are in general. They control squares and later on they can promote into queens.

6. Your opponent plays a move Ba3 which may look good as it appears to be a skewer, attacking the queen and if the queen moves, he can win the rook. But you have a good defence - you can move the rook first to e8 giving check, and your opponent has to address that so he cannot capture the queen. After that, you can bring the queen to safety.

7. At the end, your opponent moved a pawn to g5 attacking both your knights, but you can defend against that too. You can move one of the knights to attack his queen, and then move the other knight. If you move the knight from h6 to f5 it also defends the pawn on g7. But as it is, when you moved the other knight, that let your opponent checkmate you on g7 which indeed he did. That is a checkmate pattern you need to know.
