In case we were going to draw the conclusion that the loss of the cherry orchard was somehow predestined, Pischik comes along to spoil that illusion. This is a perfect example of what Donald Styan calls Chekhov's "dialectic" method of presenting a drama, taking us in and out of the play all the time with new details. Pischik is, if anything, more irresponsible and foolhardy than Ranevsky, more liable to talk endlessly in the face of impending financial disaster; in the previous Act, he enjoyed himself at the party, even though the next day a mortgage of 310 roubles was due. If Ranevsky is paralyzed by an inability to face reality, then Pischik is her "scatter-brained" nature taken to a comical extreme. Indeed, his last name, which means "squeaker" in Russian, indicates that he is a comic caricature.
But Pischik is also lucky. First of all, he is lucky to have a friend like Ranevksy who will loan him money even though she has none herself. And secondly, he is lucky to possess some white china clay on his property that Englishmen are willing to pay 400 rubles in order to lease for twenty-four years. It is of course possible, in fact, probably likely, that Pischik was just taken advantage of, but this does not change the fact that Pischik still has his property and is now in slightly less debt than Ranevsky. Pischik challenges the air of inevitability. His story, so far, has a happy ending. And this seems to be purely a matter of chance.
There is one key difference between Pischik and Ranevksy, however. Pischik possesses neither Ranevsky's idealism nor her desire to escape the present, to construct an illusion of security for herself in the world of her childhood. In Act Three, he admits he can't think of anything but money, which is natural for a man deeply in debt. Ranevsky, however, can only think of her orchard, her family, her brother, and love, and doesn't think about money at all. So even though Pischik's optimism seems much more unjustified than Ranevsky's gloom, he is tuned in to reality in a way that she isn't. He remembers the importance of money, whereas Ranevsky forgets.
