Alert: We have a prison break! Today GM Bojkov highlights the brilliant, and then not-so-brilliant, play by GMs Sergey Erenburg and Timur Gareev from the Berkeley International earlier this year. The critical features show that a trapped Rook should have led to a forced loss for white (if black had advanced the c-pawn) - but when the a4-Rook escaped, well, so did pure chaos! Try to follow the variations and improve your practical Rook Ending knowledge.
