Hi,
comrade, if you are not interested in chess but only in scores, jump to the last cross table, please
Eco A00 (Irregular Openings)
The starting position file for the GGT (Great Gambit Tournament) contains 50 gambits which are sorted by the Eco Code and have to be played with switched colours. If you like, the A00-section is a cabinet of horror-moves which occurs rarely among serious chess players. Off and on, such moves will be good for an effect of surprise. Play 1. a3 or h4 or Nh3 and it will be hard for your opponent keeping his countenance, because he feels not taken seriously. Is anybody there who wants to say: just as Tony Miles has won 1980 against Karpov with 1.a3..? I have to say, no, but it's nearly right. It was 1.- a6, after Karpov opened with 1. e4, therefore it was not an A00-game, but the effect was the same
However, there are in the A00-section a few wacky gambits too which were really played in former tournaments!
But does this concern computer and programs at all? They cannot be offended. Each legal move has to be evaluated, it's as simple as that. Good and well, but a gambit always means a sharp challenge and a precarious test position from the very beginning. Particulary, when there is no help by an opening book. With irregular moves the gambit get an additional positional pepperiness. In this regard, let's go running hot the algorithms
Amar Gambit
1. Nh3 d5 2. g3 e5 3. f4. Often cited as Paris Gambit too, but in the Wikipedia "List Of Chess Gambits" the Paris Gambit is quoted with 1.Nh3 d5 2.f3 e5 3.e4 f5. I don't know..
The Parisian Amateur Charles Amar came up with his gambit in the 1930s. Probably nobody would have communicated it to the posterity, but Savielly Tartakower, a French and Polish Grandmaster and also the King of Chess Journalism of that era, enjoyed this gambit and applied it successfully. Please take pleasure of some of his famous and often quoted aphorisms:
- It's always better to sacrifice your opponent's men.
- The blunders are all there on the board, waiting to be made."
- The winner of the game is the player who makes the next-to-last mistake.
- It is not enough to be a good player; you must also play well.
- The move is there, but you must see it.
- No game was ever won by resigning.
- I never defeated a healthy opponent
- Tactics is knowing what to do when there is something to do
- Strategy is knowing what to do when there is nothing to do."
- Moral victories do not count.
Andor Lilienthal(* 1911) is the oldest living grandmaster. He played in tournaments with many world champions and won several games against legends like Emanuel Lasker, José Raúl Capablanca, Alexander Alekhine, Max Euwe, Mikhail Botvinnik and Vasily Smyslov.

Back to the electronic competitors. Looking at the Amar starting position you may suppose that Black's king safety, the restricted mobility of the knight and the imminent loss of an accepted gambit pawn, might be followed by a negative evaluation over one pawn. But look yourself, the engines are evaluating that ripped king wing relatively harmless.

One variation of Shredder I liked very much, pushing his connected center pawns consequently into White's half like a deadly sting (game 3+,4+,24+,29-). This was Shredder's right way to catch the second place and it's recommendation for countering the Amar Gambit.
But in total, the probability of winning is daunting:
