I'm a bit surprised, as I didn't think the hard AI had significantly 
changed during that time...  Maybe you were just lucky/unlucky at how 
good a start/development the AI's got.

We really need some documentation regarding Zone of Control (ZOC)...

If those are enemy cities, then moving a land unit from the T square
to any of the three adjacent L squares would be moving from a square 
adjacent to an enemy city/unit, to another such square, which is not 
allowed by Zone of Control rules.  (With exceptions.)

(Ignoring for now some unresolved issues about whether empty cities
should count, and whether ZOC should apply when getting off boats.)
