Hooks: the one letter that turns a word into two plays

Picture a board with CAT already played, sitting there worth whatever it scored turns ago. You hold an S and not much else. Put that S in front of CAT and something lovely happens: SCAT is a new word, and the word you build crossing through that S scores at the same time. One tile, placed once, counted twice. That is a hook. It is the smallest big play in tile games, and missing hooks is the single most common way developing players leave points on the board, not because the plays are hard to make, but because they never think to look for them.

Front hooks and back hooks

A hook is one letter added to either end of a word already on the board, making a longer word that still counts. Add it at the end and it's a back hook: CAT becomes CATS, the S doing double duty if a crossing word runs through it. Add it at the front and it's a front hook: CAT becomes SCAT. Back hooks are the ones players learn first, because English plurals train the eye to expect them. Front hooks are where the quiet money sits, since far fewer players scan the beginnings of words. Both ask the same question of every word on the board, every turn: what one letter turns you into a different word? Most words have at least one answer. Some have several, in both directions, and a board full of played words is a board full of these questions waiting to be asked.

The hooks worth learning first

Start where the traffic is. Learn the hooks on short, common words, the threes and fours that appear in every game: words like CAT, and the sturdy little nouns and verbs that fill the early board. Their S hooks matter most, front and back, because S is the tile you'll hold most often with hook potential and because an S spent on a hook is an S spent twice. After S, work through the letters that commonly start a longer word when they land in front, and the common endings, D, R, and Y among them, that stretch a word by one at the back. Don't try to learn every hook on every word. Learn the fifty or so words you play most, in both directions, and the habit of checking will teach you the rest in live games, which is where hooks are actually learned anyway.

Hook blindness, and the cure

Ask club players what separates them from the level below and hooks come up within a minute. The level below plays the word in their rack. The club player first walks the board, word by word, asking the hook question, because a hook needs only one tile from the rack and leaves the other six free to form the crossing word. The missed points are not small, either. A hook play on a bonus square, with a decent crossing word, outscores most seven letter plays that don't touch a bonus. The cure is a routine, not a talent: before you play anything from your rack, name the front and back hook of every word on the board that your tiles could touch. It takes twenty seconds once it's a habit. It finds a play a surprising share of the time.

One warning that saves embarrassment

Not every word takes the hook you expect. English plurals lie: some words ending in S aren't plural at all, and some ordinary words refuse an S they look like they should accept. The reverse stings too, where a word takes a front hook nobody guesses. Never play a hook from a feeling. Check it, in a friendly game against the table's agreed list and in rated play against the official one. And since we're being precise about lists: Pangramist builds its hooks from ENABLE, a public domain list, which is not the NASPA or Collins tournament list. Hooks are exactly where two lists can disagree about a single letter, so for rated play the official list for your event settles every argument.

See the hooks on any word

The Pangramist word builder shows the front and back hooks for any word you type, computed from the same list the solver uses. Start with CAT and check yourself against the two hooks from the top of this page. Then try the words you played in your last game. Somewhere in that list is a play you missed, and finding it now is how you stop missing it.
