Isler Wins Blackmar-Diemer 4...c5

Black declined a Blackmar-Diemer Gambit with 4.f3 c5. More common is to accept the gambit with 4...exf3 or to decline by 4...Bf5. The first thought is that at least White is not going to be down material. However in this game, after 5.Bb5+ Bd7 6.dxc5 exf3 7.Nxf3, Black grabbed the gambit pawn anyway.

The battle ensued over c5 and then f4. Benjamin Isler won against Christiane Rommeck in Germany last month. Tactics were missed and mistakes made in complications from moves 17 to 20. Then White found a way to win a knight.
