History of the Marshall Attack
Frank Marshall brought this ploy into the world back in 1918. His opponent was the Cuban maestro Jose Raul Capablanca. Frank J Marshall was the strongest US player of the day having won the US Championship several times. He was also one of the strongest players in the world.But Capablanca was one of only a handful of players that Marshall just couldn’t handle. They had played back in 1909 Capablanca had demolished him 8-1 with 14 draws. Half of Capa’s wins had come when he had played the Ruy Lopez with the White pieces. Marshall had not played the Ruy Lopez with Black since that massacre. Secretly however he worked long and hard on a brand new system to beat it.He waited for so long for a chance to play his new anti-Ruy Lopez system against Capa in a big tournament game. Finally after 9 long years his opportunity had arrived.

chess engine tournament games
The new superstar of computer chess – Xiphos, by Milos Tatarevic. Released just few months ago, Xiphos is now dominating the field in Div 2 of the Top Chess Engine Championship. With 10 rounds gone, it has 7,0/10 and solid advantage over seasoned fighters such as Fritz, Nirvana, or Hannibal.
Xiphos is a UCI chess engine. The engine employs the modern search techniques and supports multithreading.This project is inspired by Garry Kasparov’s “Deep Thinking: Where Machine Intelligence Ends and Human Creativity Begins.” This fantastic book has evoked my childhood passion, computer chess. I was wondering how hard it could be to develop an engine strong enough to surpass the legendary Deep Blue, so I gave it a try.
