Morozevich as black senses an attack against a centralised king, but must open lines of attack. 22..e5! 23.fxe5 fxe5 24.Rg5 pinning the e-pawn
and after lines are open the attacker shouldn't be afraid to sacrifice. 24..exd4! 25.Rxa5 Rhe8 26.Bg2 dxe3
and the final picture is an exposed king with black's major pieces all aiming at it.
Since those first 2 wins, Morozevich has drawn with Nakamura and lost to Ivanchuk, this final game I've only briefly looked at but it appears to be a very complicated Spanish where Ivanchuk won 2 pieces for a rook and pawn and created dangerous threats around Morozevich's king. Morozevich was unable to defend, and Ivanchuk takes the lead in the tournament equally with Nakamura.
The San Sebastian Centenary tournament in Donostia has a great new format where players play 2 games against the same opponent with different colours simultaneously! The tournamnet is a knock out, where losing players can join a swiss tournament that is running alongside. Players joining the swiss are put on the same points as the leader in that tournament. All in all, it is a refreshing change from the usual events of swiss or round robin, and the games are not FIDE rated so no one is playing to defend or gain points. While there have been some upsets, I think it's a bit rich to claim a victory by a 2600+GM is much of an upset. The field is very strong with the top 5 players:
Gashimov 2757
Mamedyarov 2733
Ponomariov 2723
Moiseenko 2715
Bacrot 2714
All these players got through their first round simuls and we are now at the last 16 stage, so we're soon going to get some 2700-2700 clashes!
At Hastings the preliminaries are over and the tournament is settling into a rhythm. There are all GM clashes and each game is important in this 9-round swiss. Only 2 players are on a perfect 3/3. Istracescu of Romania and Howell of England will meet in round 4 at the top of the table. 2697 rated Wang Yue was held to a draw in the third round by Indian GM Sengupta Deep, but Wang heads a group of 8 players on 2.5 just half a point behind the 2 leaders. In this group are 2 interesting players. Sam Franklin is 17, close to 2200 and playing well above it here. He has just beaten one GM in Glenn Flear and has to face another now. That GM is none other than the ginger Simon Williams, champion of the Dutch Defence and an all out aggressive styled player.
Like Morozevich, David Howell also knows how to attack a king in the centre. Here is his first round game against FM Ryan Griffiths from Ireland. Howell as white makes it as difficult as possible for black's king to find safety. When he eventually castles, he castles into an attack. 16. g4 Nfd4 17. Qe4+ Be6 18.
