Making a proper effort to get to the end of Yasser Seirawan's "Winning Chess Endings". I just finished the chapter on rook endgames .
Finally getting to the end of this... only one chapter to go!
(With all due respects, books on chess endgames are not exactly page-turners :P . Of course, Seirawan was aware of this, and made it as digestible as he could - but there's only so much he can do to spice up the subject matter!)
