Gambits accepted gone wrong

Sort:
Mickdonedee

When accepting this gambit don't move your Knight back to safety on the back rank and block your King from castling. In this example, White brings out the Queen too early and loses it. From that point White is left to defend the King which is mated after losing too many defenders. Black wins with an accuracy of 99.4.

White accepts the Rousseau Gambit but gets into trouble again. Black pushes its centre pawns forward pushing White's pieces away and dominates the centre of the board. The White Queen is threatened and is eventually taken. From that point, White can only defend and is overwhelmed by Black's passed pawns. A promotion leads to mate. Black wins with an accuracy of 97.5.

Why retreat 5 Ng1?
The strongest move is 5 Nd4. The knight is indirectly protected as 5...Nxd4? 6 Qh5+ wins.

Spot on. However, 5. Nd4 Nxd4 leaves the Black Knight in the centre and one step away from a fork with Nc2 forking the White King and Rook. That looks threatening. Which is probably why many White players retreat with Ng1. So, learning the best responses to a gambit is very useful.

It is a waste of time to learn responses to gambits that do not happen.
If you face something unusual then it is essential to take time to think.
If you play 4 exf5 you should have looked at the obvious 4...e4. 5 Ng1 looks ugly. Would you really play 4 exf5 intending 5 Ng1?
Retreating 5 Ng1 is obvious, but 5 Nd4 is much better.

4.exf5? is just wrong because it allows Black to get a hold on the central squares, plus that the extra pawn cannot be kept for long.

One of the very first things we teach to young players (way before any opening lines) is the great importance of the central squares in order to get a good game.

I agree with you that a beginner should decline this gambit and focus on gaining control of the center with 4. d3 or 4. d4.

The Latvian Gambit is a close relation to the Rousseau Gambit except Black offers f5 in move 2! Here, White decides to develop first and then accept the gambit in move 6. Unfortunately, this still allows Black to develop a strong centre and Black goes on to win with an accuracy of 96.4.

White can get a large advantage in the Latvian by declining it and focusing on development. But 3.d3 is way too passive to achieve this (OK, I can see an "active" move in your example, which is 12.Bxh6 giving a piece away), 3.Nc3! is much, much better- white keeps the options of either taking on f5, or opening the game with d2-d4.

3. d3 blocked the White's light-square Bishop which was not in the action until move 18. So, I agree with you that 3. Nc3 is better. Then develop the light-square Bishop before d3.

White accepts the gambit straightaway and does well to castle first and prevent Black from castling. However, Black has good space to work with and does well to bottle White up in White's end of the board. Eventually, White breaks out but Black's Bishop pair guard the King strongly and Black wins a tough game with an accuracy of 86.1

After White accepts the gambit it activates the Queen early but does no real harm to Black's structure. Eventually, Queens are traded with Black's structure looking better. Black eventually promotes two pawns to mate with an accuracy of 93.2.

After White accepts the gambit the f7 square is attacked with both Knight and White-square Bishop to fork the Black Queen and Rook (similar to a Traxler). The White Knight is trapped and eventually recaptured. White castles on the Queenside. Although down a rook Black has the Bishop pair which proves decisive in winning a tough game with an accuracy of 89.9.

This is probably White's best opening line against the Latvian Gambit which includes 5 book moves and an advantage after both sides castle. However, Black trades Queens and gains the advantage eventually winning with an accuracy of 92.0.
