Itachi looked pretty shocked that he broke it, and at least half of Zetsu barely believed it. So yea, it's not common. But it's possible to do. That shock was likely faked. Like the OP said, Itachi wanted to lose, winning with Tsukuyomi would have been not conducive to his goal, of losing and dying.
