EXCITING SOLVING SHOW

The Solving Show in Riga used the format introduced by the director Vidmantas Satkus in the ECSC 2013, in Vilnius. In my opinion, the Satkus' format could give a new gas to this kind of competition, making it much more interesting, even exciting, both for the participants and the public.

The first modification relates to the used types of problems. In the more usual system, worked out by the late Milan Velimirović, only direct mates in two moves are used. Here, in each round, the competitors had to solve one direct, one helpmate and one selfmate, all of them in two moves.

Second, the format here tested, instead of the eliminatory system, uses the Swiss pairing system, well known to overboard chess players. What's more, the matches of each round are played simultaneously, all participants solving the same problems. On each table, there is a scoresheet and a pen. The solvers don’t say aloud the solution nor press any buttons to interrupt the computer show. They write in the scoresheet the first move; who writes first (who first picks up the pen) gets the point if the move he writes is correct. His opponent can look at what was written, and can only register his own move if it’s different from the move previously written. After two minutes, the clock is stopped, no one can write anything more, and the solution appears on the screen. Right answers earn a point, wrong answers earn zero. Thus, the points counting can vary from 3-0 to 0-0. But this results in victory for one side (one point for him and zero points for the opponent) or draw (half point for each).

With this system, there is a huge gain of time in the progress of the tournament, making it possible to use the Swiss system, in which no one is eliminated. Like overboard chess, there are three possible outcomes for each game: 1-0, 0-1 and 0.5-0.5. If someone loses his game, no problem. No need to go home crying onto the pillow: he will be paired the next round with an opponent who has precisely or approximately the same score as him. And life goes on, everyone has fun.

All of the competitors that I talked to loved the format.

Speaking now of the results, with two rounds to go (out of nine), it looked like Marjan Kovačević was the clear favorite. He was leading alone with 5.5 points in 7 rounds. I came to take a picture of him with two Poles, Kacper Piorun and Piotr Gorski, thinking the three of them could be on the podium. But to prove that these early celebrations never work out, Marjan, the oldest of the group fighting for the top spot, lost his thread on arrival. He lost the last two matches and fell to fifth place. The winner was the Belarusian Aleksandr Bulavka with 7 points, the runner-up was Kacper Piorun with 6.5.

Two sample problems used in the event:

(= 5+4 )
h#2

(= 8+6 )
#2
