I don't think good communication requires or is even helped in any way by asking details about someone's Scrabble past, unless this communication reveals the intense insecurity and jealousy issues of one partner or the other and allows the couple to see they are not a match. The only reason to ask for details like this would be to hold the answer against your partner, and that is simply not beneficial for a relationship. If my SO asked for details (well, he wouldn't) I would ask him why he wanted to know, because really, why on earth would you want to know that. I challenge anyone to come up with a reason why that is both necessary to the relationship and beneficial to the relationship.
