It seems to me "Direct Pointing" & "Direct Claiming" are just special cases of "Locked Candidates" types 1 & 2 respectively, in which you could find hidden singles immediately... Thus they could be applied without pencilmarks... Not sure why "Direct Claiming" is more unnatural than "Direct Pointing"...

Side Note #2:
Wang Chien-Ming of the Yankees is going for his 18th win tomorrow... And also Kuo Hong-Chih of the Dodgers is starting too... Great showing from the Taiwanese pitchers lately...
