Bug#834108: Solver fails for the Yukon variant

[Christian Knoke]

Package: aisleriot
Architecture: i386
Version: 1:3.14.1-1

A bug in the aisleriot solver for the Yukon game variant.

It suggests a move (put King of Hearts to an empty space), which
_predictable_ leads to a lost in 1, while an prospective alternative exists
(put King of Spades to an empty space) which may lead to (not predictable,
but with some good chance (because it gives you a new open card in an
otherwise cleared up game with no more then 10 hidden cards left)) - and, in
this case, actually do lead to - a win.

Prove 1. No cards are opened, and the next screen (if you follow the hint)
is a "lost game" (not documented).

Prove 2. See sequence of table shots (attached)

Another occurence of this bug (then in old-stable) has been filed under
#813945.
