How it works

A row and a column can each form a strong link when a digit has two possible cells. If one end of each lies in the same box, the links connect.

One far end must contain the digit, so a cell seeing both far ends loses it. The row and column links form the strings of a 2-String Kite.

Worked example

● evidence✕ eliminated★ confirmed

The 9 strong links in row 4 and column 4 meet in one box at R4C5, R5C4 (marked ●).

One of the remaining ends R4C3, R7C4 holds 9, so it is removed from 1 cells that see both ends (✕).
