**Dubov’s insane preparation vs. the Queen’s Gambit!!**

Hey everyone! How are you? I hope you’re all doing great—just like I hope you’re having a fantastic start to 2026. Today, I bring you a *legendary* 2025 rapid match between Vassil, Vchuk, and Danil Bov vs. Ivanchuk. Every time Mikel (Bob’s modern guy) plays with inspiration, we *must* study this game—especially against Ivanchuk, the only player feared by Kasparov. Ivanchuk opens with **1.d4**, Bov plays **d5**, and the Queen’s Gambit arises. It’s rejected with **e6**, then **Nc3**. Bob’s bishop lands on **B4**, pinning the knight and easing the pressure on d5. But the idea of B4 is *way* deeper than it seems at first—this pin has a *sinister* next move. The knight goes to **F3**, and now Bov *exposes* the pin: **Dc4**! But wait—this isn’t a gambit you *normally* take. In the accepted line, the traditional response is **e3**, threatening to take d4, but you lose the pawn and waste time developing. You’d play **B5**, but that weakens light squares (A4, C6, pawns, captures, and suddenly **F3** looks like it wins the rook endgame!). So: **Don’t take the Queen’s Gambit.** What’s Dubov’s play with **B4**?
