Classical Chess Theory holds that the two bishops are superior to a
bishop and a knight, assuming there are no other significant features
in the position. Of course, it is true that two bishops can be even be
better than two knights. But in chess, principles are particularly
frail when confronted with over-the-board decisions. And in this game,
Viswanathan Anand vs. Lev Aronian from the 2009 GrenkeLeasing rapid
World Championship in Mainz, Germany (with a time limit of 20 minutes
plus 5 seconds per move for the game), theory falls on its face.

Anand had won this event every year since Garry Kasparov last won it
in 1999. However, he dropped behind in this tourney with two straight
losses on the first day of play. He never recovered. Here is one of
his losses, against Aronian of Armenia, who won the tourney. Not only
did Anand get two bishops against two knights, he also had the White
pieces. He lost a pawn, then a second one, and when third pawn was
about to go, he resigned.
a) More normal is 4.Nc3, to take the point away from 4. . .Bg4,
although of course it also allows all the sharp lines beginning with
4dxc4.
b) Or 13.Qxb4 dxc3 14.Qxc3 Rc8 etc. and Black's initiative compensates
for Whites two bishops.
c) Black's incisive play is keeping the balance. Note how important it
is for Black to play with concrete ideas; if Black wavers then Whites
two bishops will give him the edge.
d) Or 17.bxc3 Ne4! with play against White's pawns.
e) Of course not 22.Rxa7?? Rxc5.
f) This move tries to keep an edge for White, but this appears to be
misguided. Perhaps 24.Bf3 was better, to make a draw after 24. . .Rxb2
25.Bxb7 Rxb3 etc.
g) But not 26. . .Nxf2? because then the knight is trapped. Now White
needs to find some way to untangle his pieces and keep his pawns
intact but he fails to find it.
h) Not only has Black won a pawn, he has activated all of his pieces
and he is attacking White's weak b-pawn. Rather than trade down into a
losing endgame Anand tries to complicate, but to no avail.
i) Or 34.Bc4 Rd2 35.Bxg7 (35.Bc3 Rc2 etc.) 35. . .Na5! 36.Bc3 Nxc4
37.Bxd2 Nxd2 etc.
