“Oh I love trash!”, sings Oscar The Grouch. He is especially proud of the ever-growing stacks of cards in columns 1, 5, 9 and 10.

“But what is so good about the ever-growing stacks of cards in columns one, five, nine and ten?” asks Grover.
“Well,” replies Big Bird. “The more cards you have in those columns, the less you have in others. So it is easier to get spaces in columns 2,3,4 or 8. “This is why Oscar likes his trash piles”.
“That is true,” replies Grover. “But we did not get a good deal. We can not get more than one empty column.”
“But I want to know what’s the best move!” cries Elmo, who is clearly impatient with the discussion about how best to proceed.
Count Von Count walks in, together with a couple of human guest stars – today they happen to be Bart and George.
“Before we can work out the best move,” begins Count von Count, “we need to count the cards!”
Count von Count gets all the children to name the cards, starting from the left-most column and working towards the right. As the kids eagerly announce the rank of each card, Bart draws a tally mark next to the corresponding symbol.
“King! … Queen! … Jack! … Six! … Five! … Four! … King! … Queen! … Jack! … Ten! … Nine! …”
It takes a while, but Bart eventually ends up with the image below. Meanwhile, the others are busy contemplating whether it’s possible to remove a complete set of Clubs.

“We can do it!” shout the Bad Idea Bears. “We can remove a complete set of clubs!”
“Not so fast,” says George. “That would cost us our only empty column.”
“Besides,” adds Bart, “You ain’t welcome here, you’re from the wrong crowd.”
“Awwww” groan the Bad Idea Bears. They reluctantly leave the playing hall.
It seems a better plan is to partially complete the Club suit and wait for better opportunities. If for instance we find the other Ace of Clubs, then we need not shift the Three in column 1. Or if we expose the second Club King then we could look forward to a new card more useful than the Eight of Spades.
“We should turn over a card in column 7,” says Big Bird.
“I agree,” says Count von Count. “There are four Tens unseen and that would give us two empty columns.
“Yes,” says Spider GM. “It is more important to take the card in column 7 than to remove the Club suit. Now it’s just a matter of working out the detailed sequence of moves.”
Spider GM is pleased that all his students are contributing to the discussion.
“Don’t forget,” says Count von Count, “that we are aiming to win this game with a score of 1000 or better. I believe we have played 143 moves so far.”
“Finally!” cries Elmo, as we start to move some cards around.
We reach the following position and are about to reveal what will probably be the most important card in the history of Four-Suit Spider Solitaire. If it’s a Ten then we’re in business.

And the final card in column 7 is … the Two of Hearts. It’s not the best card – then again it certainly isn’t the worst.

We now reach an all-too-familiar endgame scenario. We can easily get back a space in column 7, but we can’t turn over a new card. Fortunately there are still 10 cards in the stock, else it would be game over. How would you continue?
