Don't move a piece twice before move 10

BTW anyone know if there are any Gambits for black? I presume not as they are behind in development.

I won't advice anyone to follow any chess rule but rather think for themselves. You do NOT need to castle early if u can see that there is no real attack against your king, you can move the same piece twice or how many times if u can create threats with it or u can gain some kind of an edge. Chess is a skill. Concrete analysis is way better than following rules

Yes but after d3 the queen is hanging because it can’t move twice(discovered attack by bishop

Perhaps the rule should be stated: Don't move your piece twice in the opening unless it is attacked so that the idea is clear. There are exceptions to this, too, for instance the main line in the Exchange Grünfeld is 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 so Black not only moves the same knight three times in the first five moves but also exchanges the only developed piece he had. Both are things you should not do generally, yet the Grünfeld is a strong opening for Black (if you know what you are doing).

Are you talking about Ruy Lopez? They have to move the bishop or they lose it.

@MarkGrubb, there are gambits for Black. The first ones that come to my mind are the Benko gambit (1. d4 Nf6 2. c4 c5 3. d5 b5) in the Benoni and the Jaenisch gambit in the Ruy Lopez (1. e4 e5 2. Nf3 Nc6 3. Bb5 f5), the latter one is usually not accepted.

Probably the most played gambit for black is the Two Knights Defense. I suspect if it had the word "gambit" in its name, as it should, it wouldn't be nearly as popular.

Thanks both. I'll look them up. What does black gain for the pawn? Is it equality in development?

In Benko (and also in the Blumenfeld gambit, which is ... b5 a couple of moves later in the Benoni) the idea is that Black gets the stronger pawn center instead of White, Benko can give piece development and an open file for the rook if the continuation is (4. cxb5 a6 5. bxa6 Bxa6). Jaenisch gambit accepted leads to ...e4 attacking the knight and the only safe retreat square is g1 (though Qe2 can pin the pawn). In two knights the line is the Fried Liver Attack, where Black loses a pawn always and if doesn't know the right defending moves, may lose more. On the other hand Black has better piece activity if he plays correctly (and White can even blunder material).

In addition to those, there is the Englund gambit (1. d4 e5), which has some tricks involved, the Budapest gambit (1. d4 Nf6 2. c4 e5) and a couple of countergambits, the Falkbeer countergambit (1. e4 e5 2. f4 d5) against the King's gambit and the Albin countergambit (1. d4 d5 2. c4 e5) against the Queen's gambit. There are even more, but you rarely see them on the board.

And then there's the Latvian Gambit and Elephant Gambit, but I don't know if I'd recommend trying either.
