What is this? Doesn't 7...Nxd3+ win a piece on the spot?

Thanks

yes, this is the actual jerk that took this for himself and gave no credit

Variation on the gambit I just invented here: (Continental Ballistic Missile Gambit)

... and white is winning easily.

The Tennison Gambit is a chess opening in which White gambits a pawn. The opening moves begin with either the Réti Opening:

1. Nf3 /d5
2. e4

The first person to significantly research this opening was chess amateur Otto Mandrup Tennison (1834–1909). Tennison was born in Denmark, studied in Germany and moved to the United States in 1854. There he played in the chess clubs of New Orleans. Many strong players picked up the idea from the first half of the 20th century. 

The other name of the Tennison Gambit is the Intercontinental Ballistic Missile. Ok so lets see how does it exactly work

.

King's pawn to e4 and black responds with d5 which is the Scandinavian Defence. It is only possible with this opening. We will not care about that pawn and play nf3. Being greedy, black will take that pawn as it is unprotected and also attack horse. We will play our knight to f5, saving the piece and attacking the pawn. To defend the hanging pawn the very natural move black will think is to develop its knight and protect the pawn. Black plays knight to f6. Now we will have to Gambit another pawn so we take our queens pawn to d3. Black will take the pawn because his pawn is under attack. No we will develop our bishop to d3. Now you have essentially won the game. Black plays pawn to h6 attacking the knight. What we will do is that we will attack the f7 square with the knight forking the queen and rook. Black has no option but to play the king to f7 killing the knight and protecting the queen and rook. Now we will bring the bishop to g6 which gives a check and attacks the entire corridor. Black cannot retreat its king and has the only option to kill the bishop which leaves the queen in an exposed position. 

Done. Blacks game is over. 

WE CAN LAUNCH AN RT-2PM2 <<TOPOL-M>>CODE LAUNCH THREE-STAGE SOLID-PROPELLANT SILO-BASED INTERCONTINENTAL BALLISTIC MISSILE TO ATTACK BLACKS REMAINING PIECES. 

BUT IF YOU ARE A BEGINNER YOU CAN LAUNCH A BGM-71 TOW ANTI-TANK MISSILE LAUNCHED FROM AN M-3 BRADLEY CAVALRY FIGHTING VEHICLE TRACKED ARMOURED RECONNAISSANCE VEHICLE. 

NOW MANEUVER CAREFULLY AS OUR ATGM IS IS GOING THROUGH THE BOARD. 

SO, IT BASICALLY MEANS AFTER KING TAKES BISHOP OUR QUEEN TAKES THEIR QUEEN. 

HOW CAN BLACK MAKE A COMEBACK?

After the queen takes queen we dont need to care about our bishop on c8 we will simply move our kings pawn up 2 squares or 1 square. White being greedy will take the c8 bishop so now will take our bishop to b4 giving a check. It is a discovered attack. The king after he protects himself we can kill the queen with our rook having a very big material advantage.

It would be like this:
