In won endgame positions, computers are incredibly good and never miss a trick.

But in positions where they've lost, they tend to play really badly, often with the king running away from where the battle is, in order to delay the mate as long as possible, rather than duking it out and making it difficult to win.

Is there some way to get computers to try the sort of defensive strategies that a human would use against another human?

Where the game might finish more quickly, but the human will have had some thinking to do.

MADRID, July 26 (Reuters) - An Iranian chess player who moved to Spain in January after she competed without a hijab and had an arrest warrant issued against her at home has been granted Spanish citizenship, Spain said on Wednesday.

Sarasadat Khademalsharieh, better known as Sara Khadem, took part in the FIDE World Rapid and Blitz Chess Championships held in Kazakhstan in late December without the headscarf that is mandatory under Iran's strict Islamic dress codes.

Laws enforcing mandatory hijab-wearing became a flashpoint during the unrest that swept Iran when a 22-year-old Iranian-Kurdish woman, Mahsa Amini, died in the custody of the morality police in mid-September.

The 26-year-old has told Reuters she had no regrets over her gesture in support of the protest movement against her country's clerical leadership.

Spain's official gazette said the cabinet approved granting Khadem citizenship on Tuesday "taking into account the special circumstances" of her case.

Format

The tournament features a Group Stage followed by a Championship and Consolation single-elimination brackets. All games are 10+5.

In the Group Stage, players are divided into four groups of four players. Each group plays a single round-robin, with participants playing a two-game match against every other player in their group. If a match ends in a tie, players contest a 3+5 game, with the player with the highest accuracy score starting with White. Players keep swapping colors and playing 3+5 games until a decisive game decides the winner. Players receive 3 points for an outright match win, 2 points for winning a match in the tiebreaks, 1 point for losing the match in the tiebreaks, and 0 points for losing a match without tiebreaks.

In the Championship and Consolation brackets, matches consist of two games and tiebreakers are the same as the Group Stage.
