Possible league decider: 4-3w-3?

[Yaser Als]

Hello friends,

I have the most important match in the league tomorrow. I have been fighting this guy over the lead all season. I'm currently ahead by two points.

His team rating is two points better than mine.. They're all scouts. He played 442 classic so far and tore through every other team but I beat him in the away match.

Tomorrow is the home match and He just switched to 4-3w-3 which threw me off guard.. Now I'm not sure how to handle this match.

I really don't want to lose this one because I doubt he'll drop any points if he wins this one.

Any help is highly appreciated

Cheers!

Edit: he just bought a scout AMC and switched to 4--3w-1-2 help!
