This type of thing (snapback to produce nakade) is of course quite uncommon. It still should be possible to filter snapbacks. It is certainly easy to characterize them. However I admit that the best method of filtering them is a little unclear due to this type of example. One way would be not to accept a snapback move unless it is the only owl attack move for some dragon. Or maybe your method of giving a negative shape value is simpler and better. In any case I've been seeing snapback captures in real games and I think something should be done.
