AG
Worth 3 points before any premium square, and the 44th lowest-scoring of 96 — tied with 7 others.
AG extends into 17 three-letter words, which is the 8th most extendable of 96 — tied with 5 others. That is the number worth memorising: a two-letter word is a place to put tiles, but a well-hooked one is a place to put them where the board stays open.

Not all of them are equally reachable, which a bare count of 17 hides. AG hooks on 17 distinct letters, and the ones you are likeliest to be holding are E (60% of opening racks), A (49% of opening racks) and O (45% of opening racks). The rarest is Z, at 7%.
How often you can actually play it
Out of an opening rack, 8.84% of the time you hold the letters for AG outright, the 39th likeliest of 96. Counting a blank as whichever letter is missing lifts that to 15.62%, though spending one of the two blanks on a two-letter word is rarely the play. Exact hypergeometrics over the 100-tile bag, not a simulation.
