When installing tongue-and-groove wood structural panel subflooring, which practice BEST reduces squeaks and improves diaphragm performance?

Field-gluing the subfloor to the joists with construction adhesive in addition to nailing or screwing greatly reduces squeaks and stiffens the diaphragm. Panel edges need a small expansion gap, not a tight butt; fastening only at corners leaves the field unsupported; and aligning all end joints on one line creates a weak, hinge-like seam rather than a staggered layout.
