After quickly giving his recommendation against the 4.Bd3 variation of the Exchange Caro, GM Shankland proceeds with speed! His "rapid fire" approach to the Panov-Botvinnik Attack (where he suggests the 5...Nc6 variation) should leave everyone feeling excited to dive into these lines and use Sam's suggestions as a solid foundation for building an opening repertoire against 1.e4 around the Caro Kann!
