Abstract We show that the page at which the Lee spectral sequence collapses gives a bound on the unknotting number, u (K). In particular, for knots with u (K) ≤ 2 , we show that the Lee spectral sequence must collapse at the E 2 page. An immediate corollary is that the Knight Move Conjecture is true when u (K) ≤ 2.
