be harmless. It seems like White gives Black a lot of options - bring out the
bishop, or get an improved Catalan with dxc4, or even g6...but at the same

the latest trend of most players to try and seek advantage in non-forcing
variations - thereby reducing the effect of computers, and keeping more
creative options for the game.} (4. Nc3 e6 5. g3 {closely resembles the 4. g3

{Going into this critical last round, I was 1 point behind Topalov and 1/2 a
point behind Anand and on the same score as Giri. Having said that, Levon was
having a rather miserable event, so I felt like taking a shot to try and win.
Of course, considering my rather abysmal score against Levon with Black, I
wasn't ready to go insane, but I simply wanted to get a game.   However, I had
to also be realistic coming off an extremely disappointing draw against Maxime
Vachier-Lagrave the previous day where I missed several opportunities to win.}

illustrative lines, managing to more or less moderate the engines' initial
optimism and I thought that the next computer generations would see it more

my chess senses at all. Nowadays you can solve opening problems in a lot of
ways with the help of the computer, but it's necessary to play positions one
has a good feel for as well. Since you cannot repeat all analysis constantly,
eventually you'll get a complicated line you haven't looked at in a while and
you will easily misstep if it does not suit you.} 1-0
