BE
Worth 4 points before any premium square, and the 34th highest-scoring of 96 — tied with 18 others.
BE extends into 8 three-letter words, which is the 34th least extendable of 96 — tied with 7 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
- O→OBE
- D→BED
- E→BEE
- G→BEG
- L→BEL
- N→BEN
- T→BET
- Y→BEY
Not all of them are equally reachable, which a bare count of 8 hides. BE hooks on 8 distinct letters, and the ones you are likeliest to be holding are E (60% of opening racks), O (45% of opening racks) and N (36% of opening racks). The rarest is Y, at 14%.
How often you can actually play it
Out of an opening rack, 7.48% of the time you hold the letters for BE outright, the 44th likeliest of 96 — tied with 8 others. Counting a blank as whichever letter is missing lifts that to 15.19%, 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.
