As soon as you lift your hand away from one large chord, position your fingers as you will need them for the next one. That means, do not lift your hand from the chord, move your arm to the new position where the next chord is, and then position your fingers and play. Instead, think of the position of the fingers required for the next chord and get them in that position immediately as you lift off from the previous chord. This both makes for more efficient movement and forces you to think ahead.
