One of the little games I played without being times out

Any help will be a appreciated.and comments welcome

This is one of the very little games I played without being timed out .

It would help if you could annotate and write your thoughts down on why you chose certain moves. What was the time control if I may ask? Anyway, as you asked,

4... b5 is a bit premature.

7... Nxd5 is a mistake which he should have capitalized immediately with 8. Qf3. 7...Nd4 was correct here.

11... Qf6 is a move I fail to see a purpose for. Be7 to prepare castling was better.

Strictly speaking, 15... Ne6 is better where he is forced to exchange one of his active pieces and will help your bishop to develop after recapture.

18...exd4 , opening the king-file looks bad. Maybe you can play h6 and after Ne4 take the pawn. Or if you're feeling very daring play o-o-o here.

25. .. Rhg8 is a cute idea which your opponent refuted very well. After the simplifications it was a matter of queening the pawns for him/her.

Hope that helps.

Time limit was 1 move per 10 day but I was very keen to end the game fast cause my exams(and didnt want to add to my number of timeouts?) are  coming up.

I played 11...Qf6 without much reason . just thought that It will put my queen in a better position. didnt think about consequences (I was keen to end it quickly).

I also realized that I should have castled earlier as he subjected me to many frustrating pins. and 7. ...Nd4 looks good.

Thanks for all this advice .Will consider them in my next game.

Any further analysis?
