Rudimentary ways in which chess beginner goes on offensive, capturing rooks one by one (4,6)

'rudimentary ways in which chess beginner goes on offensive capturing rooks one by one' is the definition.
'cart tracks' can be an answer for 'rudimentary ways' (rudimentary roads or ways). I am not sure about the remainder of the definition.

'rudimentary ways' is the wordplay.
'rudimentary' becomes 'cart' (I can't explain this - if you can you should believe this answer much more).
'ways' becomes 'tracks' (track is a kind of way).
'cart'+'tracks'='CART-TRACKS'
