Blackmar-Diemer. My opening of choice lately.

Declined. :(

Seeking to bottle up the black, as c6 slows the development of the black's queen side.

? to keep the bishop from returning to b5 after c6-c5?

With black's entire army behind serrated bars, launching an all-out attack, starting with this.

as prepared by a6, challenging the center.

but I'm in attack mode already.

protects the center

! hopefully ! rather than ?! or ?. I felt I have no time to for Qxd5 Nc6 followed by Nc5, d5, f6 Nxg5 or some other kind of unpleasantness, halting the attack.

?! maybe fxg5 was better but this was more fun.
