Thus, you can eliminate the remaining candidates that share the cells with those numbers. If within the group you have two identical pairs whose digits are not candidates in any other cell of that group, then those cells will be their final position even if the solution is still unknown. Hidden pairs occur within a group and, once again, they are hidden because they share their cells with other candidates. This allows you to eliminate those candidates from any other possibility within that row or column.

You have a naked single when you find one block with one single possible candidate. In Sudoku jargon these are called naked single, hidden single, naked pair and hidden pair and they all require you to note down every single candidate for each cell in order to apply them. There are 4 main techniques to achieve this. They can be used to either find the solution for a cell or to eliminate candidates and remove unnecessary information from the grid.
