what are your favourite gambits?
I don't have one...😕 but you should try this if you want, I think at your rating level, a lot of people fall into this trap:
The entire Center Game gambit tree; especially the Danish. Recently ran into the Duras, rather liked it.
Von Hennig gambit
The gambit starts at move 4 when white refuses to take the pawn back. The next 2 moves are the most common. White can either win the pawn back now by playing Bxf7+ Kxf7 followed by Ne5+ forking the king and bishop, or attempt to go for checkmate by playing Ng5 planning to sacrifice the queen. If black doesn't fall for it, they'll most likely play Be6 after which Bxe6 gives black an ugly position (though you are still a pawn down in this line)
pls tell mine dutch gambit
