Hello all, I'm wondering how to counter this strange Xmas tree :

-----------ST-------------

------AMC---AMC--------

ML--------------------MR

----------DMC------------

DL-----DC---DC-----DR


His team is much more stronger (10/15 pts) than mine... I think I don't have any chance but I think I'm gonna use a 3N-5-2 V-style... any advice ? Thanks !
