GM Hou Yifan and open lines

Attacking the King successfully remains the most attractive part of chess. GM Hou Yifan takes advantage of the open f-file and poor placement of black's Bishops pair while it gets the black King and the full point. Enjoy!

World Champion destroys top opposition

The World Champion GM Magnus Carlsen has won another top level tournament "Gashimov Memorial" with an overwhelming 7 out of 9 score (no losses). In round 7 he took advantage of the material imbalance (Queen and pawn for Bishop and Rook) and forced GM Kramnik to resign when facing a sure checkmate. Enjoy!

GM Korchnoi teaches tactics

Do you remember that feeling your position is ripe for a nice combination? I took the challenge to solve the position GM Korchnoi built up nicely against the young GM Shaked; my first reaction was to sac the Queen, then stepped back to a more down to Earth approach of a Rxg7 sac, followed by winning black's Queen with a Bxd4 fork. Of course I did not spend nearly enough time to really understand the position; however GM Korchnoi's masterful combination is on a different level. Replay and learn from it! I did
