It's not normally something I'd quibble about, but given the nature of the article it demands it. Scrabble. Firstly, proper nouns aren't allowed. Secondly, there is only one 'z' so 'Kuszczak' would not be possible without the use of the blanks (there's only one 'k' as well), let alone 'Zuszczak'. Unless, of course you were playing Kuszczak's native Polish version where there are sufficient 'z's. Sadly, though, the effect of replacing the first 'K' with a 'Z' would not increase the score, it would lower it, as a 'z' in Polish Scrabble is worth only one point whereas 'k' is worth three. Glad to clear that one up.
