Hi. I've got a cup semi final against a team top of the league higher than me and 4 rating points better than me. He plays 3W-1-2-1-3 Narrow Diamond as follows:

DR---DC---DL
-----DMC----
---MC--MC--
-----AMC----
--ST-ST-ST--

Any suggestions for counter formation and orders.

The opponent must take this game seriously as he's already moved the game forward a few hours presumably so he can watch it.

Thanks
