2 good games I think

Constructive advice and feedback welcome

1st game:

Don't think I made any mistakes. Was pleased that I had a plan throughout even though it did change, this is something I have been working on.

1. good solid opening
2. Win center
3. stop whites attack on the king side
4. Spotted weakness on whites kingside and wanted to attack
5. Realised white had too many defenders so started to exchange them off
6. Left pieces I needed for attach
7. Attacked king and got the checkmate.

2nd Game: 

This was against a much higher rated player than me.  Again I had a plan of sorts but was forced back on the defensive.  I think I picked good moves in defence and when I had the chance struck back with some tactics that may of suprised my opponent and led to the win.
