Add or subtract

(if find no solution with +1, so I try +2 if you allow)

patriot would have worked - wish I had used that instead of portrait coming from traitor.

But I have been thinking for a while - most games I play have a house rule or two. Free Parking money in Monopoly, three second rule in Uno, no doubting a singleton lead off card in BullSpit (known by many other names), compound nouns in Word Association. ;^)

I think a good rule here is you can double up letters that already exist and I think +-2 is ok - but 3 is too much.
