Benko Gambit Accepted Capturing Defender Beginner Chess Puzzles

In the Benko Gambit Accepted, Black offers a pawn after 1.d4 Nf6 2.c4 c5 3.d5 b5, and White often accepts with cxb5. The "capturing defender" idea appears when Black uses pressure on the a- and b-files to remove a key white defender, usually the pawn or piece protecting b5, a4, or c4, so the queenside attack keeps flowing.
