Round 9
The grenke Freestyle Chess Open is taking place on 2-6 April at the Karlsruhe Convention Centre in Karlsruhe, Germany. The event is a nine-round Swiss tournament played under Freestyle Chess rules, where the starting position is altered while preserving castling rights.
Each round uses a classical time control: 90 minutes for the entire game, with a 30-second increment from move one. The tournament attracts both elite and aspiring players in a format that balances tradition and innovation.
Players competing in the parallel grenke Chess Open, which features standard classical chess, have the option to switch to the Freestyle Chess event between rounds two and five while retaining their score. This flexibility offers participants a unique opportunity to test themselves in both classical and Freestyle formats within a single event framework.

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.
