Strategy for this list
The X is worth 8 points in Scrabble but plays very differently from other high-value tiles. X sits in more valid two-letter and three-letter words (EX, AX, OX, XI, XU, HEX, LAX, MIX, SIX, NIX, POX, WOX, VOX, ZAX) than any other 8-point-plus letter, making it the easiest to dispose of profitably. On a triple-letter square in a parallel play, X can score for two words simultaneously — one horizontal, one vertical — which is why 40-plus point X-plays are common. Prioritise X-words that form crosses on both axes; the multiplier applies to both.
