Champion Tactics with GM Wolff / Interference / Lesson 12

In the 12:th lesson in Champion Tactics with GM Wolff - Interference (an excellent course btw!), on blacks reply to the first move, why doesn't the bishop capture on d3 instead of the rook?

Thanks!

Either way black is lost.  Notice that white can also checkmate with the knight from b3 and the bishop now interferes with the rook guarding that square.

Ah, of course, how stupid.. I was thinking that the pawn would take on b3 but obvoiusly it moves the opposite direction

Thanks for clearing that out.

You're welcome.  Mixing up pawn directions is something I do far too often myself.  I should actually thank you for reminding me of that course.  Interference is a rare enough tactic that I need to review those patterns.
