5... b5 is a strong move (when I learned about the FLA, I looked for a defense and this game provided that). 10... O-O seems good but it looks dangerous because many White pieces are bearing on the castle. Very nice game. Thanks, I learned a lot. (I realized this is a blitz game; but it looks good in a standard game, I guess.)
This game was in FICS, my opponent use the Fried Liver opening and I counter it with Ulvestad Varation.
We have learned how to play an aggressive opening but it is important also to learn how to counter attack.
