13...b5: ‘...for the first time I thought I was actually fighting for an advantage.’
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 b6 5.Nge2 Ne4
If you want to avoid sharp variations in the Nimzo-Indian with 4.e3 with Black, the side line 4…b6 may be an option, because here Black can hope for a more positional course of the game. Nico Zwirs examines the variation using the topical game Maghsoodloo-Gledura from the German Bundesliga (2025).
1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.Na3
Robert Ris prepared a small opening surprise for his game against the young Ukrainian FM Mykola Korchynskyi at the Open in Wolfsberg 2024: After the standard moves 1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6, our author continued with the not new but rare move 6.Na3. After the exchange 6...cxd4 7.cxd4, Black first has the option of weakening White’s pawn structure with 7...Bxa3 - Robert Ris explains why this, however, is not a good idea for Black! The main continuation is 7...Bb4+, and the game Ris-Korchynskyi continued 8.Bd2 Nge7 9.Nc2 Bxd2+ 10.Qxd2 Qxb2. Black now is a pawn up, but White has strong attacking potential after Black's short castling. In his video, Robert Ris demonstrates the complete game including the novelty 14.Nh4 prepared for that game.
