i have a small pond next to my house 5-7 acers the deeps part of the pond has a deck over it should i be casting from the deck to the shallower parts and reeling in to the deeper part of should i stand on the banks and cast towards the deck . to have a better chance at bigger fish.  

I'd sneak up to that deck from shore and cast at it from every possible angle, especially try skipping baits underneath it if possible. After I exhausted that option, I would fish from the deck.
