Best strategy is to start with the top right card (always focus on freeing up hidden cards - this is more important than playing aces, for instance), the seven of spades. Look for any red eights. There are none. Do the same with the six of spades. No red sevens. Five of clubs - one red six, but it is blocked by a black jack. Move the jack covering the six to the queen on the far right pile. Now move the red jack (and the red six) to the far left column. You can play the five on the six, freeing up a card. (It took an extra move, but I prefer playing the five of clubs over the five of spades because there are more cards hidden under it.) When you get to the three of diamonds, you will notice the four of spades, which you can move that pile to, freeing up a card. Continue with this method.
