               2.   Could or might may be used in the result clause. However, the meaning changes.
                    Would expresses a definite intention, whereas could expresses a possibility or an
                    ability and might expresses a possibility
               3.   Progressive forms can be used in both clauses

               4.   Present unreal conditions can also be used to express a future condition; however,
                    unlike the factual future conditions, these mean that it is improbable the condition
                    will take place.
