Roberson's Gambit

Post by CRoberson » Tue Aug 25, 2020 10:09 pm

Almost 8 years ago, I was in an OTB blitz match at the local club and I was in an interesting position.
I decided to spend some time and came up with a gambit I've never seen. My opponent took it and resigned after my next move.
I've used it online numerous times and it seems good. Ran it through a computer and offering the gambit is fine, but taking it is bad.
Even when they take it, they are at a disadvantage but they do have some fight, you just have to be a little careful.

I checked a couple of databases and it isn't in there.
I've taught it to several students and they are amazed at how well it works - I've only tried it at blitz and bullet, but it should be good for classical time controls.

Here it is from another game I played today:
1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Qxd4 Nf6 5.e5 Nc6 6.Qc3 e6 {the gambit} 7.exf6(accepted} Bb4 0-1

I would call it a trap rather than a gambit. You are not offering wood to increase development, but "a trojan horse" so that you can pin the queen.
So I would call it "Roberson's Trojan Horse Trap."

This is the salient point, where white should interpose his knight between king and queen, rather than taking the "gift" knight.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
