Center Counter - I let Black's Knight in!

The next game was a Center Counter. I have to confess I was slightly nervous and got psyched out (my opponent was 12 yrs old and already graded 143)! I played too hastily and my mistake was to allow my opponent's Knight to c4 forcing me to trade a Bishop for the Knight with great prospects for Black. In hindsight I should have played b3 first of all, keeping the Knight out of c4 ... I could have then played c5 with better chances. My opponent finished me off in the end with a few sound tactics ...
