You're better off just doing a pile cast where you give it a pull and let some line pile off in the water or at your feet than starting with a side cast and developing bad habits, like instinctively moving your hand off to the side.

Hard to explain, but for tight spots a hard(really hard) tug before the foward motion will help load the rod and eliminate the need for so much rod swing. Or on small water the slingshot cast, loading the rod by holding the swivel and pulling it back to the reel, like when you reel too much line in and the rod bends. When you release the swivel, the rod will straighten out and carry the business out. The release must also be accompanied by a pull off the spool just after releasing the line for any distance at all.
