Reason #1
Anand stated
that he could not play the whole game equally well from the opening to the
endgame. He feels that he didn't finish the job in each game, therefore
missing many opportunities and chances for gaining an upper hand.
Reason #2
Anand was not
able to get his confidence level up in the match against Carlsen. Some of the
endgames lost to Carlsen, Anand said he can equalize in 9 games
out of 10. But not in this match.
Anand
realized that the most important factor in this Match is not his preparation or
strategy, but the ability to avoid simple mistakes and to play most accurate
moves possible. Since if he gets a better position out of the opening and
then starts making 'unforced errors' he would just waste all the previous work
and effort.
Reason #3
Losing game 5
was a big psychological shock for Anand. He said that 'it felt like he lost not
one but three games'. He made many 'unforced errors' and after every move his position
became worse, but it still was possible to get a draw. Then, Anand made a
decisive mistake by taking the c4 pawn which loses
the game. He couldn't recover and lost game 6 as well.
Reason #4
Carlsen has
extremely difficult style to play against. In some sense he doesn't really have
a style since Magnus is a very balanced chess player, without well defined weak
and strong sides.
He tries
to 'dry' the position out and keeps playing waiting
moves to provoke mistakes from his opponent. That drains a lot of mental
energy, especially if the opponent doesn't respond with the best possible move
every time. That creates more problems and finally he loses.
Reason #5
Carlsen's
style resembles a computer, with precise and cold calculation ability, making
it difficult for his opponents to play against him.
Reason #6
In game 9
Anand had white pieces, and having '-2' score he had to play
attacking chess. In queen's pawn opening's closed position his intuition was
not enough to get the initiative and to win the game.
He took a
risk and lost. Anand said that he could've easily drawn the game, but it would
mean admitting the defeat in the Match.
Reason #7
Carlsen is
much younger than Anand, therefore can play longer games without getting
exhausted and making mistakes.
Reason #8
Carlsen's
opening preparation is not as bad as many analytics say. In fact, it's
impossible to get solid middle game positions on the highest level with bad
openings. Nowadays, computers solve most of the opening preparation problems.
Carlsen dedicates a lot of attention to the endgames and strategy in his
preparation, which seem to pay off well.
Reason #9
Anand was not
able to use his full preparation for the Match, since Carlsen did not allow
complex positions to arise.
Reason #10
Anand was
making many sub-optimal moves during this Match. Many games could have been
saved if he had avoided these 'unforced errors'.
