Dear scramblers on the List!
 
Could you tell me how many points the letter þ ("Ch") is worth in the Russian Scrabble of the American variety (Nabokov's "Flavita")? I know that in the Soviet version, commercially known as "Erudit," it is worth five points and there are two Ch's in a set. Am I right in supposing that in a "Flavita" set either there are three Ch's, or the letter Ch (a not very frequent one) is worth more points?
 
Thank you in advance,
Alexey
