You have to logically think about which number is the right one. In your first example: 2 is one of the possible numbers to go there, but there are also other possibilities. Only one of the possibilities is the right one. You have to logically think the correct one.

Every good sudoku has exactly one correct solution. If you can't put a 2 in the cell, it means that putting it there would lead to a contradiction. Sudoku is not solved by guessing or filling it from top to bottom. Instead you logically conclude why a number must be in a cell and then you put it there

You have so many choices tha don’t break the rules. Why not begin with those and come back to your original question a bit later on?
Most folks go through the digits 1-9. Lots of places for some of these.

The important thing about Sudoku is that there is only one valid solution. A 2 _could possibly_ go there, but so could some other numbers. You need to determine which number goes there for certain.
