I have a match today and dont know how to deal with it.

I win the first match and he change the tactic and now i dont know if i defend the result or try to play the game as usual.

Maybe 4-2dmc-3w-2 is a good option? or i play as usual in a 3n-1dmc-4-2?

I play home i'm 46.4 and he is 44.0

What is your opinion
