Non human 960 openings

Sometimes I play against Stockfish 960 games. I classify them in two categories. Those where module wins me and games where module humiliates me. Ocasionally I observed in few positions that some of its first moves were very strange, at least for my classical formation and conservative style. 960 is chess and center is center, development is etc, etc.
I personally play for amusement, that's why my aim is to share with you those surrealistic moves that give us that extra fun. So, I have no interest to make a deep analysis, everybody may use Stockfish, but I do want to remark the strange and shocking moves for a human player.
The adjectives I attribute to them as "strange" or "shocking" are subjective. Just because I don't think about such moves doesn't mean that others, more creative players, might consider them, and even play them. Anyway, all moves shown here have been played in a very small percentage of games between human players, assuming that they were played.

All variations presented here were found in a stroke of luck, like the finding of a treasure.

Variations are not only amusing or astonishing, but also they are useful for playing. It is possible to take ideas and open mind to a chess that can be far of classical principles more than we may think.
When I speak about board flanks, I will be using Fischer's words, 'h side' and 'a side', given that 'king side' or 'queen side' are obsolete here.

The first position I bring to this blog is starting position 351
nrkqrnbb/pppppppp/8/8/8/8/PPPPPPPP/NRKQRNBB w KQkq - 351

A weakness in a7 makes 1.f4 the first move to consider, after the most natural 1...Nb6 comes the surprise. 2.f5

Winning space in h side, disturbing the natural development, forcing to close one bishop. It is easy to explain a posteriori virtues of such move, taking apart of that you move by second time the same pawn which is unprotected and kicks all what I learnt about opening rules in my far youth.
Stockfish does not blink and evaluates this position with a +0,2.
As almost all legal moves are possible for black I wlll give two possible continuations, one trying to ocuppy the center ignoring f5 pawn, and the other trying to attack it since first move.
2...e5 3. e4 d5 4. ed5 , and here e4 square is the base of white strategy, I will show an agressive variation with an exchange sacrifice. I have not choosen the best move suggested in all cases, but I was moved by 'what happens if...?'
4...Nd5 5. Qf3 Nb4 6. Re4 Na2 7. Kd1 Bd5 8. Ra1 Nb4 9. Ne3 Bd5 10. Qe4 Nc6

Position after 10...Nc6

Bar is +2.0 after 11. Nc4 , other moves also give a great adventage for white, with a pawn and exchange down, king in the middle and without any weakness in the sight in black camp. I don't know what you may be thinking, I can see activity of white pieces, but not enough compensation. Module does not agree however is usually right.
2...e6 tries to take out that bold pawn. 3. e4 g6 4. Ne3 , notice that is difficult for black to attack the advanced pawn with pieces, 4...gf5 5 ef5 d5

Position after 5...d5

Anyone may think that black is threatening 6...d4, or at least it was what I did.
Stocky has its own ideas 5. g3 d4 6. Ng4 Qg5 7. Nb3 0-0-0 8. Qe2 Do you want to capture the pawn? Do it, 8... Qf5 9. Nh6 Qg6 10. Ng8 Qg8. Pawn down and a knight moved four times to capture a trapped bishop.

Position after 10...Qg8

Nevertheless after 11. Qb5 starts the party.

Those two variations after 2.f5 were not the best ones for black, they were choosen for my own curiosity and search of funny variations. Is 2.f5 a move to be considered seriously in other starting positions? Well, the configuration of Bg1 and Na8, Rb8 is present in many other positions. Is it always good? No, according to my humble experience and it is not quite easy to understand when it is good and when it is not. I made some hypothesis but contrast is needed.

Of course 1...f5 is possible for black. There are another jokes in this case.
