Sorry Berrecci, yet at move 14 e5 is different.  But then white has a discovered check and white will gain the d pawn and either another piece or the g and h pawns

Excuse me friends, but the orginal quesiton concerned 14... e5, NOT 15... e5.

On the 14th move the bishop is still in place.

As Nibir's diagram shows, once the bishop has already been removed the question of playing e5 does not arise.

How can Black play exd4 here

Ok, someone will have to show me exd4 after 15.   e5 16. Nd5 Nxd5 17. exd5

I don't see a bishop on the e file at move 15?

Jlueke - no, the bishop is still blocking the pin

good..

Berrecci, black couldn't play 16 exd4 because the pawn would be pinned by the queen.  So e5, which does look good at first doesn't gain a piece and creates some weaknesses that Carlsen is likely looking for.

I do wonder about the plans for both sides.  Wa Carlsen looking just to provoke either d5 or e5 and did he have a plan for both?  One would think yes.  If black had played e5 earlier how would white attack's proceed?  

As for black what was his plan after spending all that time with the knight to remove the dark squared bishop?

Kidnap - on Ponomariov playing 14... e5

It makes you raise an eyebrow on first viewing, doesn't it, but on reflection this is a honey-trap! Initially it appears to fork the knights and win a piece but after:

15 Nd5 Nxd5 16 exd5 exd4

Black is a piece up, but then:

17 Bxd4+ leads to a prolonged headache for Black - going by superficial appearances, the material will be recuped with a continuing White attack, and Black will have to forgo the luxury of castling.  Someone may be able to do some proper computer analysis, and even come up with some refutations, but as RP avoided this line in the game, I doubt there is anything strong!

in Carlson vs Ponomariov 

Ponomariov could have played 14....e5 instead of playing 14....Nxe3

this could earn Ponomariov a peice

Anand or Kramnik will be the winner???

Kramnik v Leko was exciting, but according to Mig at the Daily Dirt, it has all been played before in 1989 by two different players!!!

Kramnik-Leko was a great game (19.Bxg7 wow!), in fact it was much more exciting than Carlsen's straightforward win against Ponomariov's bad play.

Kramnik - Leko was truly exciting I think.

A good win for Carlsen, he continues his incredible unbeaten record!

What happened to Aaronian?

It's all set for an exciting final round. Let's see who actually has steel nerves. Hopefully its Anand but for that to happen I guess Kramnik should play badly because he has clearly been the best so far in the tournament.
