What is this opening called?
Just thought of something though. In the Krejcik Variation, although it prevents the black king from castling, it appears that black will develop its pawns a lot quicker than white. Is this a fair concern?
Not at all. Black's pawns, in fact may become overextended. White may want to play Qe2, c4, Qxc4 where by e-isolated pawn becomes a problem.
I was referring to 2. ... d5.
i.e. 1. e4 Nf6 2. Bc4 d5
2. ... d6 is also fine for Black, and 2. ... e5 would transpose to Bishop's Opening.
Even if they did play the line you suggested, it doesn't look like a refutation, as Black has traded a flank pawn for a central pawn, and he also has two bishops, which some people like.
As you learn more about openings, and strategy and tactics in general, it is not always best to go for a "free pawn." This is a perfect example, as 2. ... Nxe4 leaves Black in bad shape.
2. ... d5, after the most common 3. exd5 Nxd5 leaves Black pretty well off. Black has choices of where his minor pieces can develop, with plenty of freedom and little pressure on his position. Experienced Alekhine players will be aware of this trick (2. ... Nxe4).
here is the refutation:
Refutation to 2. Bc4?
Because that's a pretty nice position for black, hes king is not in that much danger and he has the bishoppair and a nice center, black should at least be slightly better in my view. ^^
Agreed! It reminds me of a kind of Dutch, where there is no more Nf6, but Black can play Qf6 and Be7, and he is fine. Even prepare ...g6 later for the king to go to and the king rook can come out to play.
I am 2042 and I play Alekhine's defense as black. First of all, 1.e4 Nf6 2.Bc4?! is not critical at all as far as I am concerned. Both 2...d5 and 2...Nxe4! (my choice) are sufficient for equality and probably more. 1.e4 Nf6 2.e5 is of course critical, when the main line goes 2...Nd5 3.d4 d6, when white has a choice between 4.c4 Nb6 5.f4, the aggressive four pawns attack, and 4.Nf3, the modern grandmaster choice. There are a few sidelines, but those are most important.
