AS
Worth 2 points before any premium square, and the lowest-scoring of the 96 — tied with 35 others.
AS 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.
Every hook
- A→AAS
- B→BAS
- F→FAS
- G→GAS

- P→PAS
- R→RAS
- T→TAS
- V→VAS
- W→WAS
- H→ASH
- K→ASK
- P→ASP
- S→ASS
Not all of them are equally reachable, which a bare count of 17 hides. AS hooks on 14 distinct letters, and the ones you are likeliest to be holding are A (49% of opening racks), R (36% of opening racks) and T (36% of opening racks). The rarest is K, at 7%.
How often you can actually play it
Out of an opening rack, 11.48% of the time you hold the letters for AS outright, the 26th likeliest of 96 — tied with 7 others. Counting a blank as whichever letter is missing lifts that to 18.38%, 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.
