Last week we asked the following:

**Is it possible to determine the identity of the next unknown card for all columns containing at least one face-down card?**

The answer is no. I can get columns 4,5,6,9,10 but not 1,3, or 8.

The problem with column 8 is we need to build off-suit with 3-2 to get the empty column, but then there is no Four or Three to shift that off-suit 3-2. One empty column is not enough. I will not discuss columns 1 and 3. That has already been covered last week with Bart and Schistocerca Americana’s (SA) excellent comments. Well done again to Bart and SA. I guess the next step is to take the easy turnovers and take it from there.

BTW Thanks also to Sebastian for liking one of my recent posts. I hope to hear more from him.

We reach the following position (both the current game state according to Microsoft Spider Solitaire and our cheat sheet) with the five newly turned over cards highlighted:

Let’s just say these are not the most helpful cards. At least this can partly explain why I lost this game rather convincingly without undo. It seems to be hard enough to win, even with the undo Awesome Superpower.

I guess we can take some freebies in column 4 at the expense of dumping a King into an empty column. This leads to the following:

And now we reach a dead-end. There are no more easy turnovers and we have to make some choices. If we think about long-term planning (rather than short-term gains) then there are three basic choices to consider:

- Go back to the very beginning and look for more turnovers without dealing anything from the stock
- Go back to the first position of this post(score = 141) and try to arrange matters so that the next deal of J-6-2-5-4-A-3-8-8-K is as helpful as possible
- Look for ways to remove at least one suit to the foundations, given the information we already know

Stepping back for a minute, we can observe a problem with Fours and Nines. Despite turning over more than half the cards in the tableau we didn’t find a single Nine. We know six of these are in the stock. We only managed to find two Fours at the expense of dumping a King into an empty column.

Over to you. How would you continue here?

**A small reminder: Microsoft Spider Solitaire will not allow a player to deal a row of cards if there is at least one empty column.**
