The best Scrabble players are the strategic ones who keep adding words to their player vocabulary. Once you've mastered a number of two-letter words and the high-scoring ones (that are admittedly very difficult to play), start looking to double-letter words to take advantage of the multiples on your tile rack.

1. AGLOO

Don't have an I for IGLOO? Use an A for AGLOO, meaning an air hole through the ice made by a seal.

2. ALLEE

Instead of an ALLEY, use this double-double-lettered word meaning a tree-lined walkway.

3. BETTA

Rather than BETA, use that extra T to mean the freshwater fish.

4. BRATTICE

A BRATTICE now means a heavy curtain or barrier in a mine to help direct air flow, though the medieval meaning was simply a temporary partition along a wall.

5. DRESSAGE

The fanciest of all horse training and equestrian events, DRESSAGE is the obedience and discipline riding competition, rather than the racing.

6. FUGGY

To FUG is to make something stuffy or odorous, but its adjective form (FUGGY) and past and present participles (FUGGED, FUGGING) will take care of any extra Gs on the board.

7. GHYLL

Not only will GHYLL, which is a deep ravine, utilize a double-letter, but it will help if your tile bar is sorely lacking in vowels.

8. GRAAL

GRAAL is an older form of the word GRAIL, but it's also a technique used in glassblowing.

9. HEELER

Don't have an A for HEALER? A HEELER is a person who puts heels on shoes (as well as an Australian cattle dog).

10. HELLUVA

If you're having a HELLUVA time getting rid of a few letters, this nonstandard combination word is actually Scrabble-approved.

11. INNAGE
