Sesquioxidizing is not in any official scrabble dictionary, but should be, even if only for its magically positioned q, x and z. The word lives on the web, it can be found in "The Archive of Endangered, Special, or Fun Words", with the text: 'the word is derived from the word "sesquioxide", and thus not found in the dictionary directly'.
Using sesquioxidizing and otherwise TWL06 words only, on a day that things go your way and with the rack DGIQSXZ one can get 2015 points [upper image]... the bigger SOWPODS dictionary makes a difference. Words like 'jabberwock(s)', 'talaq', 'leylandi(i)', 'highfaluting' and 'acidulent', none of which are in the TWL06, allow a 2044 points move with the rack DGQSZXI [lower image].
