The Move of the Year?

The EICC finished yesterday in Jerusalem and as far as I can see from the various pictures, great coverage of the event and thoughts shared in internet it was a greatly organized event.
It is hard to say which of the games played in Jerusalem was the best, everyone will definitely has his/her own preferences.
The following game however is special. It was played in a crucial moment, round ten of the event and the winner was receiving a chance to play for the title. It was also crowned by a spectacular move which will stay in the treasury of the chess world.
A game that I liked (ChessBase 13)

Tomashevsky's Endgame on Video

Three light pieces versus a rook is a rare endgame, but a recent game by Evgeny Tomashevsky (versus Maxime Vachier Lagrave) placed in into the spotlight. In this video I will try to explain the winning mechanism for the stronger side.


25.2.15

Very Unusual Endgame

Round eight of the Tbilisi Grand Prix witnessed a highly unusual endgame. Three light pieces were fighting a rook. According to my Megabase, there are only eight predecessors of this endgame!The tournament leader Evgeny Tomashevsky extended his lead after a demonstration of an excellent technique.

there is time to advance them. If not, they will be targets. The three light
pieces can easily unite their efforts attacking any of the pawns and it will
be lost as the rook cannot separate itself into pieces. The general rule is
that the smaller parts should be better than the major piece as long as they
are united. This is the case here, the pieces are clearly better. One more

Rare Weapon against the Leningrad Dutch

GM Grigor Grigorov of Bulgaria was kind enough to send me the following interesting article, enjoy!
Hello dear reader!
I have the pleasure to introduce you in the extremely interesting Leningrad system in Dutch defense. The flexible pawn structure in this variation makes the arising positions very difficult to be analysed with a computer. One needs deep understanding in order to treat correctly such types of positions. That's why the Leningrad system is the favourite choice of creative players like Nakamura, Bartel and Malaniuk.
In the present article I would like to share with you my favourite weapon against this dangerous system. The variation that I am going to show you is not only positionally sound, but also it's less popular than the main lines. My practice shows that the majority of the players are not well prepared against this rare line. You can also seize the opportunity to cause nightmares to your opponents.
The main position arises after the moves:

his last move white prepares the advance e2-e4 after which the rook will be
able to excerce pressure along the semi-open "e" file. I would like also to
emphasize on the fact that white hasn't played yet the move c2-c4 and and he
has the possibility to restrict the "g7" bishop by means of c2-c3.} Ne4 {The
main move in this position. Black takes radical measures against the pawn

possible continuations.} (7... Nc6 {[%cal Ge7e5] Very interesting idea. Black
not only prepares the e7-e5 advance but also increases the pressure over the
"d4" pawn. The main drawback of this move is that the knight is placed in
front of the "c7" pawn. As a consequence, the "c" pawn can no longer
participate in the fight for the center by c7-c6. Furthermore, as it will
become clear later, in some cases whis could use the restricted mobility of
black's Queen In genearal, you must think twice before placing your knight in
front of the "c7" (c2) pawn!} 8. e4 $1 {In order to use the "bad" position of

Despite of the fact that white's advantage is obvious, I would like to give
you some useful tips which will help you to convert your advantage in such
type of positions. As you could see, black has enough ressources to defend the
weakness on e7. That's why we should try to create a second weakness in
black's camp. In order to achieve that, we should take the following actions:
1) Exchange white-squared bishops by means of Be4 in order to make use of the
weakened "e6" square. 2) Place the rook on e6 while the queen should on e4.
