I normally play against Computer (medium strength) and lose always.This is one of those games.I play white.Any suggestions?

I have plauyed a lot against Computer (Easy Strength).

 

5. Bd3 is weak. It blocks your d pawn (which you will likely need to fight for the center) and prevents the development of your dark squared bishop. Instead 5. d4, or Bb5+ or Be2 are better, depending on your preference.

 

8 gxf3 creates an unnecessary weakness in front of your king. Qxf3 is much better.

 

9. Bf5 isn't great. Black could of responded with Nd4 and launching his attack on the exposed king. 

 

Instead of 10. d3, f4 looks interesting. Attacking Black's pawn center and perhaps exploiting the fact that Black hasn't castled yet.

 

12. Bxh5 wasn't necessary. The bishop is lost anyway, better to use the move for something else such as Bg5.

 

As you saw d4 wasn't a good move because of the fork after the recapture.

 

You moved your light squared Bishop four times in the first twelve moves, while your dark-squared Bishop never took a step. A better square for the light squared bishop followed by either d4 or d3 and then developing the dark squared bishop and you would have had a very playable position.

I usually make a lots of mistakes it seems.Pointing to a specific one and how can I turn this game into a winning one for me will help tremendously.

 Thanks Richard for your advice.

Updated my initial comment with more detail.

I feel i might be a bit too new to kibbitz, but just a thought here:  it seems like the computer will always choose an exchange over a retreat.  At 6...Bg4, you respond h3.  The computer is definitely going to take your knight at this point rather than back out of Bg4.  Your only recourse is to weaken the castle with 8 gxf3.  What if you had gone Qxf3 instead?  Too early to move your queen out?  I don't know... But I think the point at which your castle was weakened marked the decline of your game.  If you had not responded to 6...Bg4 and move your queen from the pin...maybe it would have changed the outcome?  Arguably something like Qe1 in response to 6...Bg4 could have still resulted in 7...Bxf3 where you really had no choice but to respond by doubling your pawns and weakening the castle.  But then again, had you not done 7...h3, it may have given you more time-- black may have chosen to wait a little at its own expense before take f3.  By the way at 12.Bxh5 I wasn't really sure of the reasoning.  I understand the threat on b4, but then after 12, Bxh5, black has two possibilities for the h-rank for its rook.  Anyhow, I usually lose too.  Thanks for sharing your game and giving me the opportunity to give you my thoughts.
