The Canal & Prins Gambits - Two Surprising Weapons against the Queen's Gambit. Opening Hacker Files, #15

The Queen's Gambit can be rather boring, especially for Black, so a couple of weapons to make things more excitement. In this book, FIDE Master Carsten carefully analyzes two gambits for Black that both arise after the initial moves 1.d4 d5 2.c4 e6 3. Nc3 Nf6 4. Bg5 c5!?. The Canal Gambit arises when White captures 5.cxd5, and Black responds 5... Qb6. The gambit is somewhat dubious, but very effective in practical play.
The Prins Gambit instead sees Black respond 5...cxd4!?, which is a correct gambit, giving Black full compensation for the sacrificed pawn. All of White's responses to both gambits are carefully analyzed. Prepare to give White a wake-up call!
