I would guess the most common place would be 31.Qxf7+ ( {idea} Z0
32.Ne8{followed by} Z0 33.Bf8 +- )
Or in the sentence 'anymove'.
There was a CB post here (in the CB-pgn debat) with a nullmove that wasn't at
the end, and also in CA it don't need to be at the end.
Tho it isn't nice of CA or others to extend the pgn like this, espesially when
they have a switch to turn on CA-extention to pgn for exchanging files between
CA-users.
They could just add these moves in the comment field for their compatibility
format and all would be happy :)
