public class Person
{
    public string Name { get; set; }
    public IList<Person> Descendants { get; set; }

{
    // Here `MergeSequentialChecks` rule is triggered for both `&&` operands.
    public static bool MergeSequentialChecks(Person person)
    {
        return person != null && person.Descendants != null && person.Descendants.FirstOrDefault() != null;
    }

    // Here `MergeSequentialChecksWhenPossible` rule is triggered.
    public static bool MergeSequentialChecksWhenPossible1(Person person)
    {
        return person != null && …
