Watch out about "connected passers."

give white two pawns on d2/e2.  Give black two pawns on a2/h2.  Both kings
in the center.  Which side do you like?  :)

This happens a lot vs GM players, once they see the hole.  They will
happily give you those two connected passers.  :)

Connected passers are good when you have pieces...  But with no pieces,
look out.
