Dumping two blots into your board is generally not a good idea when
your opponent is eager for a good opportunity to break anchor, but
an important factor here is O's extremely inflexible position. For
example, if X maintains his 10pt then 51 and 61 are anti-jokers
for O.

I don't think you're using anti-joker correctly.
