This game was played at the recently concluded Mauricie Open in round 2. It is an interesting game that is typical of hedgehog structures - White launched an attack, but Black was able to defend it and was able to get counterplay and winning chances. Enjoy!

structure. While White has a space advantage, Black is extremely solid and has
a very flexible position. An interesting plan in these positions is to try and
play a4 and a5 to create weaknesses in the Black structure.} 17. Rad1 Rfe8 18.
