Highest total combined score in scrabble? - Answers

My best score so far, playing solo, is 3584 points. This was accomplished on January 3, 2011 by using the 15-letter word "oxyphenbutazone" on one margin and "sesquicentenary" on the other, both set up so playing 7 tiles creates 3X3X3 scoring, while doubling the 10-point values for Q and Z. For these two words a base score of 2481 was attained. There are other high-scoring alternatives i.e. demythologizing, dichlorobenzine, nephrectomizing, conceptualizing, etc. "Blaxploitaton" is of interest because it positions the x in the fourth place. Adding "prejudicialness" vertically over the two remaining triple word scores, (3X3) adds 252. There are many possible approaches to this puzzle, and total combined Scrabble scores far in excess of this one are certainly achievable.
