Blackmar-Diemer Poisoned Pawn 8...Bxc2

In the Blackmar-Diemer Gambit there is a wild BDG Ziegler 8...Bxc2 line which is like a Poisoned Pawn line. How ironic it was that my opponent "PoisonPawn" grabbed that pawn in a three minute blitz game last year. I know the first dozen moves of this variation pretty well, but at a speed of 2-3 seconds per move, I miss stuff a lot. Nowadays theory favors the solid retreat 8...Bg6 as Black's only chance for advantage.

Our game shows the real vulnerability of the Black king in this 8...Bxc2 line. That marked monarch is caught in the middle and under assault from all the remaining White forces. Computers usually find wins for White in this Blackmar-Diemer Gambit line, but humans may or may not depending on knowledge, tactical skill, pattern recognition and time to calculate. I won quickly but could have won even quicker.
