Vienna Game 2… c5 | Brilliant Knight Sacrifice! ⚡ Quick Wins #75


chess noob Quick Wins! is a series of short videos, to demonstrate very quick wins! As a beginner, you become aware of the Scholar’s Mate and the Fool’s Mate, but neither of these show up in real games. However, there are tricky quick checkmates and wins that occur, even at the intermediate level of chess.

Today’s game was a very quick unrated game I played a few weeks ago! It’s a great example of how setting up an early attack with a trap can catch out an opponent, especially someone at the beginner-intermediate level!

I had the white pieces, and the game starts with the Vienna, and Black plays a slightly suboptimal response (1. e4 e5 2. Nc3 c5). Interesting! I develop my king’s bishop to the usual square (3. Bc4) – which immediately places pressure on Black’s weak f-pawn on f7. Black now brought their queen to the field of battle with (3… Qe7). This is against opening principles – bringing out the queen too early can result in the opponent harassing the queen with their minor pieces, which can result in the loss of tempo and potentially material!

We see this as I could immediately attack the queen with my knight, placing it on a powerful square for the queen’s knight (4. Nd5) which forced Black to move their queen a second time (4… Qd6). Moreover, Black’s queen didn’t have any specific targets was simply a bit awkward on that square.

At this point, I saw a potential trap and brought out my own queen (5. Qf3!?). Stockfish calls this a “mistake”, but I had set up my bishop and queen to potentially double-attack the f7 square – a checkmate threat. Black doesn’t see the looming threat and plays another pawn developing move (5… g6) and this slow move was pretty much game ending!

Next move, (6. Nc7+!!) – an absolute fork of Black’s king and rook and a brilliant knight sacrifice! Black’s must move the king and lose their rook if they wanted to avoid mate, but the temptation for Black to capture my knight with their queen was just too strong (6… Qxc7??). With Black’s queen now on the c7 square, she has trapped her king on the back rank with a [+M2] – (7. Qxf7+ Kd8 8. Qxf8#). GG!

Notice in this game that the game ended in checkmate while Black hadn’t developed any of their pieces other than their queen!
