Scrabble SavvyYou want to dominate at this game so fiercely that people will think you've memorized the dictionary. Here's a few essentials. First, know all of the legal two-letter words: AA AD AE AH AI AM AN AR AS AT AW AX AY BA BE BI BO BY DA DE DO EF EH EL EM EN ER ES ET EX FA GO HA HE HI HO ID IF IN IS IT JO KA LA LI LO MA MI MU MY NA NO NU OD OE OF OH OM ON OP OR OS OW OX OY PA PE PI RE SH SI SO TA TI TO UN UP US UT WE WO XI XU YA YE Note: these are the legal two-letter words in the Official Scrabble Dictionary, version 3. If your cousin happens to have version 4, which was just released, then you'll also need to know FE OI QI KI ZA. And be prepared to scoff and say, "Didn't you know that 'za' is slang for pizza in California?" You will often be questioned on the definitions of many of these, even though it's not technically part of the game. Be ready to quickly state, "Of course I know what 'xu' means -- it's a form of Vietnamese currency," or "You didn't know that 'ai' is a three-toed sloth?" And, for the icing on the cake, to guarantee that you will win every game, don't forget that QAT, QANAT, QAID, and QOPH are all legal scrabble words. In other words, most Scrabble players think their vocabulary is great -- like most casual investors think they are good stock pickers, most drivers think they are above average and most poker players think they are great bluffers -- so doing a little basic homework is enough to gain a significant edge.
