Round 6
Bacrot 1/2 Leko
The game of tournament leader league Etienne Bacrot proved to be less than exciting. Playing the white side of a Spanish game with 6.d3 against Peter Leko, he followed his own game against Ernesto Inarkiev from the 2016 European Team Championship, through move 15. The always well-prepared Leko had to play a few precise moves, but generally had no trouble holding the balance.
Ponomariov 1-0 Navara
David Navara had to lick his wounds after yesterday's defeat against Hou Hifan, standing at a disapointing 50% score, but instead Ponomariov poured salt in them:

previous games. White has the advantage of the bishop pair, but Black has
the more active rooks, the Be6 is well placed and his king is
safe. Because of the pawn weaknesses, both sides have opportunities for attack and the position is double-edged.19.Rg1Rfc820.Kb1Nh520...Rxc2?!N21.Bxa6R8c622.Bb7Bxa2+22...Rxb2+23.Kxb2Qxb7+24.Ka1Ne8But here black is fighting only for a draw. In the medium term

Ponomariov improves his position. His only problem remains the
f3 pawn, however, the Navara has no way to seriously threaten it.Nf425.Qb4Nh3(?)25...Rd826.Rfd2Ng6 And the counter-play
against f3 is sufficient for the time being. Yet Navara is not out of the woods yet, and Ponomariov can try to find chinks in the armour at will.27.Be227.Bg2Nf428.Bh1ist zu passivQe7=27...Nf4!26.Bxh3Bxh3I have the feeling that the exchange of
the knight for White's light-squared bishop is not a good strategy.
On the one hand the Bf1 was very passive, but on the other hand
Navaras Springer ensured a control of the dark squares and served
(on g6 or f4) as a bulwark for his king.27.Kb2Qd828.Qd2
Ponomariov now aims his queen towards the kingside. Pressure against the

When choosing an opening repertoire, there are days when you want to play for a win with Black, when you want to bear down on your opponent’s position with a potentially crushing attack. The Najdorf is perfect for just such occasions. Strategy, combinations, attack and defence, sacrifices and marvellous manoeuvres — exciting chess is all about the Najdorf!

Harikrishna 1-0 Hou
The India vs. China matchup ended in favor of the former as Harikrishna leapfrogged Yifan to keep pace with Pono.
Unleashing complications with 37.g4
Harikrishna's timing was perfect, as the Chinese had to calculate some difficult variations just as the time control approached. After the sequence 37...hxg4 38.Qxg4 Ra8 39.h5 Kg7 40.hxg6 Hou was under pressure:
Position after 40.hxg6
At this point both 40...Rf8 and 40...Rg8 hold the balance, but after the obvious move 40...fxg6, Harikrishna came up with 41.Qd7. The black king was now much more vulnerable than White's monarch, the and once Harikrishna's rook was able to join the attack, there was no hope for Hou.
Position after 45...Qc8: Harikrishna's 46.e5! activates the rook and combined with the potential advance of the d-pawn here was no longer any way to defend.

Georgiadis 1/2 Morozevich
Nico Georgiadis has played an outstanding tournament. Undefeated with one win, is an unexpected position for the young Swiss facing such tough opposition. Today he even had Alexander Morozevich under pressure. Morozevich sacrificed a pawn for some compensation but had to fight his way to a drawn queen ending.

Vaganian 1-0 Studer
An exciting game was played by Rafael Vaganian and Noel Studer. Vaganian sacrificed an exchange for positional compensation in the center. In a confusing endgame, Vaganian's connected passed c- and d-pawns raced against Studer's passed h-pawn, and in the end, as often happens in these games, a single move decided:
Here Studer could have drawn with the surprising 51...Rxc5+ as after 52.Bxc5 Rh4+ 53.Kd5 Rh5+ White has nothing better than to repeat.
A hard defeat for Studer, his third straight loss as he fades to clear last place.
