One of these positions is an impregnable draw fort for white, the other is vulnerable to attack and can be demolished. Which is which, and (for extra kudos) why?
I hope this one is not too easy for you...

Re: Puzzles
Here is my bid.
Position 1:
f4 and h6 can be captured. Hereafter no more whites are exposed, provided that the king remains on the throne. White uses f7 to make its compulsory moves.
Position 2:
The same as before, but f7 is missing so that white cannot do its compulsory moves without destroying the fort. Instead there will be in the continued game a hard fight to complete / prevent a fort.
A fort can be completed with two moves: g5-h5 and g6-g4.
The position can also in several ways be reduced to the [ www . tim-millar . co . uk / section509308_183637 . html ] "Royal Citadel", fx. e8-e7, e5-d5 and f5-e5.
All this black will try to prevent.

Re: Quiz question
Very good answer Hagbard! Perfect in every way. I'll have to think of a more difficult conundrum...
