how to deal with an unfamiliar openings

I was playing black, and i was faced with 1.b3, the move itself is not so bad, but i knew that i was going to be in an aggressive game and had to avoid all the tricks.

if i missed any parts, just let me know and i can help answer

I play this against b3

Great game! Nice analysis!

8. Nf3 and white has no problems
