GM Perelshtyen shows how to employ the Exchange Variation as he often has at the GM Level. The Exchange Variation 1.e4 c6 2.d4 d5 3.exd5 cxd5 is a very subtle line for white to fight for a long-term positional advantage based on a rapid development of your two bishops that will make it very difficult in turn for black to develop his bishops to active diagonals.
