A Two-String Kite ties a row strong link to a column strong link for the same digit. The two links meet inside one box — like two kite strings tied at a knot.
Like a Skyscraper, it is a very short single-digit chain (strong–weak–strong) — a tiny AIC / X-Chain where one of the far ends must be true.
Before this: Same family as Skyscraper — short strong–weak–strong on one digit.
Why it works
Each string is a strong link: exactly one end is true. Because they meet in a box (weak hinge), they cannot both be true at the meeting side in a conflicting way — the logic forces at least one of the far ends to be true.
Any cell that sees both far ends cannot be the digit. Same “stung either way” idea as a Skyscraper, with a box as the hinge.
Demonstration
Find a strong link for a digit in a row, and another in a column.
If they connect through the same box (weak link), you have a Two-String Kite on 4 — strong–weak–strong.
One of the far ends must be 4. Cells that see both far ends are caught in both worlds.
Eliminate 4 from cells that see both far ends (red).
Example 1
Link a row strong and a column strong on one digit via a shared box.
This is a Two-String Kite on 6.
Remove 6 from cells that see both far ends (red). At least one far end must be true.
Example 2
Link a row strong and a column strong on one digit via a shared box.
This is a Two-String Kite on 2.
Remove 2 from cells that see both far ends (red). At least one far end must be true.
