The notion that Macbeth could apply his military skill to deposing the king is something that Macbeth’s wife is eager to inculcate. Although Tamieka Chavis could do more to bring out the conniving and, oh, let’s just say it, evil nature of Lady Macbeth, she’s very effective late in the play embodying the desperation of an ambitious spouse whose greedy plans result in a disastrously short reign for the Macbeths as a royal couple.
