This gambit was just played at Tata Steel 2022 and it’s a must watch as you will likely see it soon in your own games! Eugene also presents a cool idea to neutralize the Nimzo-Indian 4.Bd2, old but tricky line that’s getting more and more popular. Also, don’t forget to check out the A-bomb! A completely new idea in our beloved Grand Prix Attack, 5.a4! Watch the videos and start playing this right away!
