your #24 is my #28 (typo or my suite is off?)
Anyway this one is BAD.The defending side made a poor move
as posted previously

Also BAD as there is no decisive plus score. At least my understanding
is to have a suite that produces a decisive advantage.

Bg6 looks strong with this line:
1.Bg6 Rxe2 2.Bxh5 Rxe1 3.Rxe1 g6 4.d6 Bc6 5.cxb5 (Rxb5 or axb5)
6.Bg4, followed by Rc1 and d7. This one is fuzzy as black can
put up a stubborn resistance despite a piece down. It would not
hurt to delete this one in any event.

the Qf2 Rd1 then d2 plan looks strong but may not be decisive
enough.

This one is BAD as the defender mis-stepped.
