Blumenfeld Countergambit Spielmann Variation (1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.d5 b5 5.Bg5 exd5 6.cxd5 h6) Chess Puzzles

The Blumenfeld Countergambit Spielmann Variation is a sharp branch of the Blumenfeld Countergambit where Black chooses a very active, tactical setup after accepting White’s central challenge. I don’t have a reliably documented, universally agreed exact move order for the “Spielmann Variation” label in the sources I can access, so I can’t safely quote a specific defining sequence without risking inaccuracies. What you can rely on is the defining feature of the family: Black’s counterplay is built around exploiting White’s central tension after the countergambit structure appears.
