I'm making a merged sgf of the Master games (so you can see at which points humans and it diverge in the common openings), and wondered what way round to normalise the (big) orthodox fuseki of a 4-4 and shimari: on the right side of the board or the top? It's common to start in the top right corner, so if this is a 4-4 you can end up with 2 orientations depending which corner white plays for 2:

Of course there can be other ways of ending up with an orthodox, e.g. starting with a 3-4 at top right and then playing the 4-4 bottom right and then making the shimari, but that seems less common (e.g. because if white 2 is top left they might approach for 4), though you do often see the shimari plus 3-4 arise that way (e.g. black/Lee in the 'AlphaGo game 5 opening'). In making a game collection I would usually not bother rotating/reflecting games to have a uniform orientation, but keep it as the players created (though of course game recorders may record from different point of views), but for this merged tree normalised is better.

Anyone who chooses top is history's greatest monster.

I like how top is the bottom diagram. I was thrown off at first.

I just switched them to reduce cognitive disonance (or whatever). I wonder if there is a mental bias to pick the first one? ;-)
