If for issue 4.A.3, choice b, c or e has been taken, then the move from
Sweden to Norway is not a convoy and the English fleet in Norway is
dislodged and the fleet in Skagerrak will not be dislodged.
If choice a or d (1982/2000 rule) has been taken for issue 4.A.3, then
the move from Sweden to Norway must be treated as a convoy. At that
moment the situation becomes paradoxical. When the 'All Hold' rule is
used, both the army in Sweden as the fleet in the North Sea will not
advance. In all other paradox rules the English fleet in the North Sea
will dislodge the Russian fleet in Skagerrak and the army in Sweden
will not advance.
I prefer the 1982 rule with the 2000 rulebook clarification concerning
the convoy to adjacent places and I prefer the Szykman rule for paradox
resolving. That means that according to these preferences the fleet in
the North Sea will dislodge the Russian fleet in Skagerrak and the army
in Sweden will not advance.

If a unit is attacked by a supported unit, it is not possible to

Italy:

F Albania - Trieste
First it should be mentioned that if for issue 4.A.3 choice b or c is
taken, then the move from Trieste to Venice is just a move over land,
because the army in Venice is not moving in opposite direction. In that
case, the support of Venice will not be cut as normal.
In any other choice for issue 4.A.3, it should be decided whether the
Austrian attack is considered to be coming from Trieste or from the
Adriatic Sea. If it comes from Trieste, the support in Venice is not
cut and the army in Trieste is dislodged by the fleet in Albania. If
the Austrian attack is considered to be coming from the Adriatic Sea,
then the support is cut and the army in Trieste will not be dislodged.
See also issue 4.A.4.
First of all, I prefer the 1982/2000 rules for adjacent convoying. This
means that I prefer the move from Trieste uses the convoy. Furthermore,

that the army in Trieste is dislodged by the fleet in Albania.

the final result would contain two units that successfully moved to
