    When I find places on my deck that tend to retain water (low/cupped spots) I drill a small hole in the center of the puddle to let the water drain through the deck. 3/16 to 1/4 inch holes are sufficient. The holes don't effect the appearance of the deck significantly, and they should help retard the weathering of the deck.
