Stubborn Defense

Fabiano Caruana significantly improved his tournament situation in Shamkir after an important win with the Black pieces against the former world champion Vladimir Kramnik.The Italian GM had to survive at first the strong pressure that his opponent put on him. The moment in which Kramnik decided to open up the game was not chosen right and the tables have turned into Caruana's favour.

this leads us to the conclusion that Kramnik succeeded with his opening
strategy. Now he starts slowly torturing his opponent. The grand plan is to

In his younger days Teimour liked to play very sharp in the opening. However,
he did not play the Main line since 2011.} e6 7. f4 Qb6 {Diagram [#] The
Poisoned Pawn variation has its ups and downs. Of lately it seems as the
interest towards it is rising again. White waits until the second player gets
the deceptive feeling that all is good in this line for him and stops checking
the forced lines. And then White strikes! At least this is the way I explain
the fashionable trends in the line :)} ({In their previous encounter Alexander

Pawn variation had arisen. Black has two extra pawns and White-three extra
pieces in the attack. It can hardly be sharper than that. Both the sides have
to be extremely precise in what they are doing. Grischuk came up with a novelty
