Thanky all of you very much for your advices.
I played 3-2 zone and won :)
@thylacine : i knew that he will play Motion. He played LI agianst me becouse i play the defense that suits the opponents offense, and i knew in the regular season that he will not play Motion, and then i chose to play then M2M.
But i was pretty sure that he will play motion in PO, which actually happend.
Thanks again and good luck 4 all of you !
