100% guaranteed win!! Kings Gambit Declined; BeepBeep Counter-gambit!!!

That says more about your opponents than the quality of the move however

Panteldakis Countergambit (C30) is a very weak response to the King's Gambit for black. Plus there's no such thing as "guaranteed win" in chess.

Even "super" Grandmasters miss their chance to mate in 1 and go on to lose at the highest levels of chess. Take Viswanathan Anand's final play off blitz game with Vassily Ivanchuk at the PCA World Grand Prix, London in 1994. http://www.chessgames.com/perl/chessgame?gid=1018510
Move 29 Black (Vassily Ivanchuk) could have taken White's rook with his queen: mate. Instead Black went on to lose by time. Check out the video here:   https://www.youtube.com/watch?v=sI49dVO74mE  

Hey BeepBeep : I beat a 2700 ( bullet : he is 1500 OTB ) on lichess.org multiple times. and also another One who is a FM. This doesn't make my openings guaranteed win. I can play 1.e4 a6 and beat a 1200 easily. I beat a 1600 OTB with that.

Wow. I checked the explorer and the one time you played that opening (as black) you lost.

Isn't it just like the adelaid wahls countergambit?  I think that one inserts Nc6 before f5.

 His bullet is 332. May be he beat 200 rated player 10 times in a row and count that opening as a nearly 100% win.

LMAO Also, I guess it would require a special huge effort to attain such a low rating.

 Wait, his post and profile is quite similar to 2Q1C, is he coming back?

You may never lose with this trash but in my level ( 1800+ Classical on lichess ) , It can't work .

It`s probably the same person. People can be thrown out of Chess.com and come back under a different email address. I guess he`s having fun. But if he ever comes to my club and plays that crap, he will be asked to leave.

This Panteldakis Countergambit is objectively bad but take it easy, U can find something good the next time.

I`m tempted to go to Russia and speak to him personally about his silly idea. I don't have the money or even know his true identity.
