This is indeed a new improvement, thanks Roberto.

It depends whether the record to establish is the max of moves from  
the thematic side, or the max length of the game. I prefer the second  
option, as it asks for some more imagination to be able to add a last  
half-move from the non-thematic side.

Suppose there is a new improvement in 23.0 with, say, one more  
homebased piece but impossibility to add a last half-move. In that  
case I would think the record still belongs to the 23.5 game, don't you?
