Semi-Queentri:
(I think it's better!)
The rest on the pieces I didn't move, because you have a choice in life, so make the right one.
In the Semi-Q, the d-pawn won't move twice - after the rooks are in place, it's bombs-away!
Okay, time for a 'test-drive', let's see how goes.
The Queentri (Queenside-Triangle):
Queentri is an improvement to The Batmobile:

Which was practically a failure, because it has no 'real estate' claims near the center (aka, pawns), and the pieces don't have enough room, and the king isn't safe.
Queentri allows both bishops some air, controls center-squares, probably solid - like the original triangle, but doesn't entomb a bishop. King is safe in K.I.D style - that's pretty solid. Middlegame plan very simple: rooks to d & e, center-pawns forwards!
