HoDoKu Two String Kite

There are only two positions for 5 in both row 2 and col B (the two strings), and they both hit box 1 (the kite), therefore G6 cannot be 5.

The logic is: There are only two possible positions for 5 in row 2:

  1. If cell C2 is 5 then B3 cannot be 5 (same box),
    therefore B6 must be 5 (only remaining position in col),
    and therefore G6 cannot be 5 (same row).
  2. Alternately, if G2 is 5 then G6 cannot be 5 (same col).
Hence there's only two places for 5 in row 2, and neither allows G6 to be 5.

Therefore G6 cannot be 5.
