The speaker suggests putting the hands a little forward at address and notes you can putt with your eyes directly over the ball or slightly inside it. He describes applying some pressure with the putter head and moving it away, so that by the end of the swing the shaft and the forearm are in one line. He offers it as an interesting feel to try.
