Psychologically, maybe both players were trying to prove to the othe ...[text shortened]... heir preparation was better (by moving almost instantly) and Anand was just a bit too quick.
I lost a game to gatecrasher very similarly. it was one of those standard deep dragons that people always go for in CC (because that's where the db leads), and at some point quite deep in I forgot we were in a Kb1/Re8 line (I don't use dbs), and sacced the e2 exchange at move 25 or something. the lines are otherwise identical, except that the sac doesn't work. after a few futile attempts to complicate matters I resigned.
the reason I made the mistake wasn't because I hadn't worked both lines thoroughly. it was
because I had worked on them
so much that the autopilot took over.
I think the same happened to anand. he would've never missed the knight sac if it was a random position. because that's pretty much the first move you look at, the brutal axe murder attack. but because he knew the lines, and knew the king was supposed to end up in f7, he simply mixed up the move order getting there.
