Magnus Carlsen himself managed to beat MVL in the final round of the London Chess Classic to finish joint-first. Subsequently he won the blitz-tiebreak. The Kupreichik starts with 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Bd7. It is a flexible move, as it doesn’t tell white much about the set-up black will choose. Most often black goes for a Dragon or a Classical Sicilian set-up. It depends a lot on white’s 6th move. In some cases, it will even transpose to a Najdorf. One of the advantages there is that black hasn’t committed to a6, so a5 can also be played in one go. More details and benefits are explained in this 60 minutes course which will provide you with a good and surprising weapon for black!
