Hi everyone!! I need uor help!!

I play 4-1-2-1-2 narrow diamond.

Tomorrow i have game against the first place in my league, use 4-3-1-2( 4 defenses- 3 MC - 1 AMC - 2 ST), and thursday i play against second place in league and he use 4-4-2 classic.

What would be the best tactic for each of the games?
