I played the game below (1.d4 Nf6 2.c4 e6 3.a3) where White's third move
was obviously designed to stop 3...Bb4+.

What would you play as Black's 3rd move in this case? It seems a rather
rare opening (I can't find many games like it), but those that I have
found, White Black normally plays 3...d5, rather than the 3...c5 I played.

3...d5 don't look very nice after 4.cxd5 exd4, where Black has lost one
of his central pawns for one from White's c-file. Strangely, on the few
games that I have (only 16, although I've not gone around the web
looking for such games), White only once played cxd4, which rather
surprises me, as it seems quite logical.

I don't feel I did too well with 3.,,c5 either.

Thoughts?

There's a saying that you can't play any of the fancy defenses to 1.d4
until you can defend the QGD. Now, I don't want to defend that saying in
all cases, but let's play with move orders here for a second.

Imagine you played:

1.d4 d5 2.c4 e6 3.a3 Nf6.

Same position. Black is already fine - so long as he doesn't play a
defense where a3 turns out to have been a useful move. (eg, you wouldn't
play for a Cambridge Springs defense anymore). I think most annotators
would give white's third move a ?.

3.cxd5 exd5 goes into the exchange QGD. Now there are some lines where
this can be tricky for white, but white's advantage hangs by a tempo.
And guess what he just wasted? White's already given you freedom for
your pieces and the time to develop them in an organized fashion.

I strongly, strongly, strongly recommend Sadler's book on the QGD.

"similar with 3..c5

it should have been

after 4 d5 exd5 5.cxd5-d6 6.Nc3-g6 7.e4-Bg7..etc..

Either one 3...d5 or 3..c5

The idea is to get into a variaton of a standard opening where the a3
pawn move is purposeless, is a waste of tempo(move). And thus, with one
move in addition, Black equalizes.

for instance

1. d4 d5 2. c4 e6 3.Nc3-Nf6 4.cxd5-exd5 5.Bg5-Be7 6.e3-c6 7.Bd3 ! (but
if 7.a3 ? then 7..Bf5! and black has reached equality here) and now
Black can not play Bf5 to solve the problem of developing the light
squares bishop ( a typical problem in 1.d4-d5 openings )...usually the
theory goes with 7..0-0 8.Qc2 !
[but not 8. Nf3 ? Bg4! and again Blacks solves his problems and
equalizes]
8...Nbd7 9.Nf3-Re8 10. 0-0-Nf8 11.h3 and Black still has problems to
bring Bc8 to play
on a useful square]

therefore one thing to do is

1.d4 Nf6 2.c4 e6 3.a3 d5 4.cxd5 ed5 5.Bg5 Be7 6.Nc3 c6 7.e3 Bf5! with
equality

similar with 3..c5

after 4.d5 exd5 5.Nc3-g6 6.e4 Bg7 7.Nf3 0-0 8.Bd3 Re8 9.0-0 a6

you are in the Modern Benoni with a tempo in addition for Black because
here White must play 10.a4 to stop b5! (otherwise Balck gets an easy
game with his queenside countreplay and threatens then b5-b4 chasing
away the knight that defends the "under siege" e4 pawn)

usually the correct opening goes as
1.d4 Nf6 2.c4 e6 3.Nc3-c5 4.d5 exd5 etc. so the a4 in response to
Black's a6 is done
when is done in one move...

in general losing on move when playing White is enough for Black to get
equal

That's why 3.a3 is hardly ever played, you give up to your advantage of
playing White without a fight.
