Blackmar-Diemer

Gambit accepted fully.

Two pawns down, three officers in play, all lines open, nothing left to do but attack.

to clear e6 to get to f7

This felt like I had no choice. All the officers are in place and there is nothing painless left to do.

! This one scared me. But Blackmar-Diemer is about attacking, so...

!? ...so when in doubt, I keep attacking. Is this valid? As for Bxe6, I felt the only choice was to sacrifice or retreat.

Opens g6 for the knight, allows pinning an undefended officer at e5, clears the route to the black king, keeps up the pressure so black can't bring its material edge to play.

Qf7 loses at least a rook after Rd8+ Ke7 Qxf7+. Kd8 leads to Ne6+ and Ke7/Kd7 to Qxg7+ with imminent checkmate.

to open the e-file.
