The setup for problem 62 is wrong. Here's the correct setup: Click Here To Show Diagram Code `[go]$$B Problem 62 $$ ------------------ $$ \| . . . . . . . . . $$ \| . X X . X X X O . $$ \| .

Yeah, that appears to be the solution to number 63. I couldn't find it at first, and I just thought it was set up wrong. Gah, my tsumego skills are so out of shape.

Thanks a lot didnt think of (a) which is bizarre as the problem before this one (which is shown above) is almost exactly the same and I found that answer right before attempting this one.
