Yeah, Scrabble is one of those rare games where I don't mind the "analysis paralysis." Usually during that time I'm plotting my own master move (or not) anyway.
Do you ever find yourself in this situation? Your tiles are, say, R-D-E-N-U-U-U, and you think to yourself that you could probably have a decent shot at a 7-letter word if you got rid of one or two of those U's. Do you swap tiles? That would be my instinct but I've noticed pros don't seem to swap much. What do they do instead? Try to use the U's? Give up on the 7-letter word?
