Scool Scrabble Tool
Scool is a tool for finding valid letter combinations for Scrabble. It currently uses the TWL06 wordlist. We'll add other wordlists in the future to complement TWL, such as SOWPODS.
You would benefit by memorizing these:

 

Construct your own queries:

Like:

Use the following placeholders for the like query: % matches any number of characters; _ matches exactly one character, !negates; @ intersects (AND's) the results. The like query is a fast and flexible way to find words matching a pattern.

 

Anagram:

Sub-anagrams are coming... stay tuned!

 

Where:

The where query is more advanced. It lets you define the SQL WHERE clause manually. For example, here's a query that finds all 7-letter words with 'able' somewhere inside them.

Add d to 2-letter words
