You can find many annotated games if you check some higher-ranked players at www.cross-tables.com. Pull up a player's page such as Mack Meller and there's a whole slew of games he's played which you can view.
Actually, the point values should be printed on each tile so they do not have to be memorized, though it may help in considering the opponent's responses if they have certain letters that combine with yours.
And it's also acceptable to have a pre-printed scoresheet where one can track the letters that have been played so that would show the frequency of each.
Tracking helps one a lot at the end as you know what letters your opponent has and can adjust your play to suit. Of course, at most tournament level play, they have been tracking and know your final rack too.
Sorry, but you do not *want to "basically memorize every word that uses the high scoring tiles." Rather, you want to study the low-scoring tile-filled words because those are more likely to be found on one's rack.
A key to high-scoring games is scoring "bingos" or using all 7 letters in a rack in a single turn as it gives a 50 point bonus. This is why we're taught to memorize the word lists that have such letters as TISANE in them as that string combines with most every other letter to make a bingo. The letters in TISANE are 1 point each.
You also don't want to leave vowels (all of which are worth 1 point each) adjacent to the bonus squares. A parallel play with an I under/to the right of a triple-letter-square can easily score 62 if one puts a Q on the triple and another I to make QI both ways.
Yes it's theoretically possible to have two light-squared bishops due to promotions but so exceedingly rare that I think most professional chess players will go their whole career without ever seeing that happen.
Promoting to anything other than a queen is rare, and I expect the next most common is to a knight. Promoting to a bishop, while possible, is going to be extremely rare.
My cheat was to write the formula for quadratic equations for a TI 57 with its 50 step programming capacity. I just put in the a, b, and c values then R/S (run/stop) and it'd spit out the answers on a red LED display for the high school algebra test I was taking in 1980 as a freshman.
