## Example of a Knights Move

##### This is a version 12.0 screenshot

### Knights Move:

A solution is not allowed if it is a chess Knight's move away from another

Square containing the same solution.

In this example, the 2 on B3 means there cannot be a 2 on A5 or D4. The 2's in those Squares (outlined in orange) are impossible solutions and can be removed.

## Second Example of a Knight's Move

##### This is a version 12.0 screenshot

### Knight's Move:

In this second example, both Squares of the

Double on H5 and J6 can 'see' G7 via a Knight's move. Therefore, G7 cannot contain a 6 or a 7.
The 7 on G7 (outlined in orange) is an impossible solution and can be removed.

## Third Example of a Knight's Move

##### This is a version 12.0 screenshot

### Knight's Move:

In this third example, all the 1's in the indicated

Box can be 'seen' by the 1 on C9 (outlined in Orange). If C9 was a 1, it would wipe out all the
1's in the Box. It is therefore an impossible solution and can be removed.
