Tactical stuff

[jerby]

some say that RTW is strategically just as deep as a shotglass..but that's not the reason why i started this topic.
i've got an (advanced )tactical Q, to everybody.

this is teh scenario:
Seleucids vs ptolemoi. each side has 8 units of pikmen(equal quality)4 units of Cavalry(equal)and 1 unit of elephants(same quality) flat ground. ptolemoi defending. with their 8-pikemen in 1 strait line; 2 cav on each side. and elephants behind cav on the left(our/seleucids left)

What woudl be your tactic if you were the Seleucids?

Note:sides are equal strength. i chose for 'units' in stead of numbers to make it easier to divide contignents. this is not a historical scenario. just a question of tactics were you have "No advantage except tactics".
