Tomashevsky Attacks

After the free day the ETCC in Iceland entered the decisive matches. In the men section Russia managed to score one more important win. The big Man in this match was Evegeny Tomashevsky. Known for his clean positional style, the Russian champion proved that he is also a dangerous attacker.
A game that I liked (ChessBase 13)

Chess diagrams are amazing, is it based on Javascript or a diagram software like creately ?
