Another point. It is highly likely that the opponent used a computer here. I
base this on a couple of things. Near the end, there is a deep mate. He played
it _perfectly_. Which I don't think an 1800 player could do. If I were
betting, I would bet that white is a computer.
If I were to criticize moves, I would pick the following moves for black as
suspect (from a human perspective): 11. ... Bh2+ seems totally pointless.
23. ... Qb7 seems to be worse than pointless. This is a queen, not a bishop.
I also don't like 24. ... a4. Advancing passers is often good, but the further
they advance, the easier they are to attack and the harder they are to defend.
White is attacking on the kingside. Black really doesn't need to waste time
on the queenside just yet, when he has no pieces for defending the kingside.
However, on the other hand, Tiger was playing a computer in human clothing.
Nothing good can come of that, and drawing conclusions is harder. I would
_never_ believe than an 1800 player can beat today's programs. yes, it might
happen once in every 1000 games. But that is close enough to zero to instantly
turn on warning lights when I see it. In this case, if you analyze the game
with another program (I used Crafty) it couldn't find any improvement for white
from move 18 on. Which is _very_ suspicious...
