One more little hint that might have helped. Sometimes don't play cards from the waste when you can delay them and then play up a card to the tableau. If this gets you a space, then having some nice cards in the tableau will clear the next space sooner. This helps you get at good cards that you can't play immediately. I.e. if you get a space sooner, it might let you save a key card in the tableau instead of having it deeply buried in the waste.
This is a game I am happy not to play more of. But if I've counted right, at time of writing I've now got out 14 of the 20 most difficult games in Solsuite.
