The importance of CCT: example #6 - Dortmund 2013 round 1

As part of the continuing series on the importance of CCT (Checks, Captures and Threats) to your thinking process, here is the round 1 game from Dortmund between Vladimir Kramnik and Wang Hao.  Visually it's easy to understand why Black assumed that his last move 25...Ra2 was safe, as it cannot be safely attacked by White's rook and White's queen is on the same file with a White pawn in between them.  With that assumption, Black evidently did not bother with falsifying his move and calculating his opponent's CCT.  However, following the queen check on b8, which forces 26...Kh7, White has the queen fork on b1 and it's all over.
