2. If you see two identical digits next to each other, the cells on both ends must be the opposite digit. If a row or column already has half of one digit, all remaining cells must be the other.
3. If filling a cell would make a row or column identical to another completed row or column, that placement is wrong. Use this to eliminate candidates.
