So far, there was some excitement in Chennai, but you could hardly say that the tournament was satisfactory. It missed what really is the core value of every sport: Victory and defeat. Magnus Carlsen decided it’s …

Understand The Position 28: “The Chess Simul”

Understand The Position 28: “The Chess Simul”

In this part, it will be the first time when we will be looking at the position from the game played on www.chessfriends.com. This is one of my regular Wednesday’s simultaneous games. I played against five opponents and since I was not doing very well a week before, this time I was trying to concentrate as much as possible. I managed to win four games, however, in the fifth one, the following messy position arose:

Markos-KrejcikM, www.chessfriends.com, White to move:

Black is up the exchange, but his rook is pinned. White pawns are very much advanced, but their king is not able to reach them, at least until the Re5 is captured. If White had waited, Black would have been able to play only …Kc7-Kb8-Kc7-Kb8, everything else loses the game. Time: I had about seven and Black about three minutes on the clock.

I was checking the capture on e5 first. 1.Kd4 Kb8 2.Bxe5 dxe5 3.Ke4 but it leads nowhere. Black simply plays 3…Kc7 and White will not be able to attack the pawns of his opponent. He has to take on e5 and to agree with a draw.

Immediate 1.Bxe5 dxe5 2.Kb5? g3 3.Ka6 g2 4.Ka7 doesn’t work because of 4…g1-Q+.

The winning continuation is: 1.Kb4 Kb8 2.Bxe5+ dxe5 3.Kb5! (the only move because 3.Kc5 Kc7 or 3.Ka5 Ka7 is even losing) 3…Ka7 (after 3…Kc7 4.Ka6, White is gaining a tempo and winning the game. Black cannot advance his pawns – he would get mated after Kb5-b6.) 4.Kc5! I missed this triangular maneuver. It is very difficult to realize the fact that in such a “fast” position of the pawn ending with running pawns a loss of the tempo may actually lead to win. This loss is actually a profit in this position – black monarch was lured to the unfavorable field.

Now the horse-race follows:

4…g3 Kd6 g2 6.Kc7 g1Q 7.b8Q + Ka6 8.Db7+ Ka5 9.Qb3

After the bishop vs. rook endgame and pawn endgame are gone, the queen endgame arose on the board. White is winning easily here even though the material is balanced. Black e5-pawn is so far from its promotion square that it has practically no cost. Furthermore, Black would rather prefer to be without this pawn because it restricts the queen in checking. With just a bit of skill, White can push the c6-pawn to the rail.

In haste, I didn’t find the winning continuation. Therefore I played risky, let the rook out of the pin and almost lost the game. Finally the game ended in a draw.

    Hello my chess friends. it’s cool that we can play this beautiful game when ever we want. I would like to compete in the tournament. Can you tell me how to enter the competition. Greetings, Vojin

      Very cool! If you have a aaoimuttc version that will just exercise the chess engine, I would happy to profile with our internal tools against the Flash player and see if there are any other bottlenecks that the Flash Profiler would not catch. A program that just ran aaoimuttcally without user interaction using all CPU would be ideal.

      I womlece your point about every tournament being a part of the jigsaw, and that is why I am opposed to the Fed-Ex Cup. Every tournament is important in its own right, and should be recognised as such. Come and check out my blog and follow it if you are intrigued, or share any of my opinions. A bit of debate wouldnt go amiss either!
