Another handicap 13x13

I've opted to instead apply the first handicap options from Sensei's Library for 13x13s. The table is reproduced below. It's easier to understand.

 Difference  13x13   Komi   Difference   13x13   Komi
  0         0      5.5       10        4       5.5
  1(*)      0      5.5       11        4       2.5
  2         0      2.5       12        4       0.5
  3         0      0.5       13        5       5.5
  4         2      5.5       14        5       2.5
  5         2      2.5       15        5       0.5
  6         2      0.5       16        6       5.5
  7         3      5.5       17        6       2.5
  8         3      2.5       18        6       0.5
  9         3      0.5       19        6      -3.5

Found a little time so I played against Aya100 (21k?) and won by 11.5 moku. I probably should have applied a 6-rank difference instead of a 7-rank difference since the rank had a "?" at the end.

Then too, I don't know for certain that my rank is 28k.

Still much to learn. At least the handicap system allows me to expand my choice of opponents.
