The Nimzo-Indian has stood the test of time for over a century: Still a top choice for elite players today, from Magnus Carlsen to Praggnanandhaa, it remains one of Black's most reliable ways to fight for real chances against 1.d4 2.c4 3.Nc3.
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.
Italian Game Powerbase 2026 is a database and contains 8571 top class games from Mega 2026 and the Correspondence Database 2026, of which 479 are annotated.
If you're looking for a dynamic alternative to the Slav, Queen's Gambit Declined, or other mainstream systems, the Chigorin Defence offers exactly what modern tournament players need.
