1.c4 e5 2.Nc3 Bb4!? is an opening idea well worth considering. Black immediately threatens to double the pawns on c3 in the style of the Trompowski or Sicilian Grand Prix attack. White must let this happen or avoid doubled pawns with either 3 Nd5, 3 Qc2 or 3 Qb3. All of these possibilities lead to sharp and interesting play. On this 60 minutes course let IM Andrew Martin introduce you to this system and hopefully inspire you to play it!
