Some odd openings I had in mind

Do these openings exist? If yes, are they often played?

Since I don't know that, I gave them names :

THE FRANKENSTEIN'S GAMBIT

THE COUNTER-SPANISH OPENING

THE ULTIMATE QUEEN'S PAWN ADVANCE

THE FRENCH RUY LOPEZ

I'll be adding some.

Knight's Gambit

Maybe this KGD.

Have you tried them in real games?

After the Scotch and the Ruy Lopez...

I`m no expert, but i like the openings

The 'knight gambit' one is actually called the 'Halloween Gambit'

The "Frankenstein Gambit" could be significantly improved by not playing 5...0-0, but rather accelerating it with 5...Bg4 and keeping the rook on a8. A passed edge pawn in the middlegame is usually well worth a piece, and I think this is one of those situations. Black will castle queenside and have rooks on a8 and b8... The kingside pawn offensive will be unstoppable.

It would be even more improved by not sacrificing a piece for nothing (in the OP, 11.Be2 and it's 1-0).

As for the kingside offensive being unstoppable, in the event of Black castling queenside in a KID, hmm... which kingside are you talking of ?

In this N's gambit / Halloween Gambit; I guess after 5... Ng6 black has a well better position. Doesn't work.

I think the one I take the most seriously is the 3. c3 move I think really interesting.

The French Ruy Lopez... don't know... really don't know

The Ultimate QP Advance transposes (after 2... c5 3. c4) to a Benoni easily.

King's Gambit Ruy Lopez... the same

Counter-Spanish seems a little interesting.

Frankenstein's Gambit is just... IDK, maybe for bullet chess?

Thanks for pointing that out. I took about a 30-second-long look at that position and didn't really pay any attention to what I was about to post.

There is this for black:

Once, I played something with f5-h5-g5-g4 early but I don't remember what it was.

e5 against d4, you mean...

Indeed. There is an reason these 'odd' openings are rarely played, especially in this day & age of databases, opening explorer...etc. In fact, some of these moves can be found in such opening trap books written in 1958-90's. (ie Byrne, Mednis, Chernev, Horowitz, Pandofini...). Maybe you could dig up games from the early 1900's.

As it is, you could always play these OTB.

1) (Frankenstein - funnily enough, this name is used for another opening FYI) This just loses a piece for insufficent compensation. (Blunder: 8...Bh5??) You will see piece sacrifices in the King's Indian, but usually in closed positions where the black pieces already have a clear route to the king. It just doesn't make sense here at all.

2) (Counter Spanish) 3.d4! looks strong. White can sacrifice a pawn for huge compensation after something like 3...Qe7 4.dxe5 Qxe5 5.Nf3. 3...Qh4 is similar. 3...exd4 4.Qxd4 seems to at least lose the bishop pair for no compensation. It looks really risky.

3) (Queen's Pawn Advance) is a positional error. 2.d5 c6 3.c4 cxd5 4.cxd5 e6 5.Nc3 Bb4 6.dxe6 fxe6. Black has the better center and a lead in development. I prefer exchanging with c-pawn slightly, as it frees the c6-square for the knight.

4) (French Ruy Lopez) is another strategic error. After 9.f4 Nxd4!, White comes under heavy pressure. The bishop on b5 is often tactically vulnerable after ...Bd7 (...Nxe5 is a common tactical theme French players are familiar with). If White exchanges pieces on c6 after Black has defended the pin, he loses his good bishop and is often worse.

5) (Knight's Gambit) is called the Halloween Gambit and is probably the best of these. Nice idea if you found out this yourself. However, 6.d5 Bb4! =/+ is known to be a safe antidote for Black. Black returns the piece and has the better game.

6) (KGD) I don't think this would compare well with 2.f4 Bc5 as the bishop is shut out.

7) This is the Ponziani, a very old opening. 3.c3 d5! is probably the strongest move.

I've seen a few of these in games of lower rated players. If you understand the main lines, you will see the defects in many of these ideas. If you want to do opening research, you should consult a database and have an engine on hand. However, you should probably find a general reference book as a guide. Fundamental Chess Openings by van der Sterren is one book that comes to mind.

HOW DID I GET 300 VIEWS WITH THAT?!
