CCC Practice Game

[Graham Banks]

I doubt it will play Rfd1 if we play a5. I could be wrong but I do doubt it highly. If (and it is a big if) we got Rfd1 then a4 straight away.

Most likely is that we get Bc5 however.

Christopher

15......a5; 16.Rfd1, a4; 17.Bc5 could still be troublesome if you look further at it.

17. Bc5 gets 17.......Ra5!! and we have equalised (or are even in front).

Christopher

I don't have a board in front of me, but here is what I had on the ...a5 and then ....a4 idea (boy, its getting to be a pain to scroll back in the thread to quote myself):

15...a5 16. Bd3 g6 17. Qg4 and I am not sure what to do for black here. 17...a4 is met with 18 b4, but I don't see much better.

If memory serves, the b pawn looked pretty annoying in this position (after axb axb). If Chris and folks can find a way to get ....a5, ....a4 to work without some preliminary work I am all for it. I couldn't find it.

-Sam

I agree with Sam's assessment of that position.

Sam if 17...a4 18 b4 runs into 18...axb4 e.p. Rxb4 (there is no white pawn in a3) and Rxa2 we recover the pawn in a good position.

Perhaps you also did not see this?

I told Steve to make separate threads for each move.

Imagine if the game goes 100 moves.

Anyway......Bc5 is very good for us in that line.

17.....a4; 18.b4, ab; 19.ab is okay Tano-Urayoan.

Ok this is the position if 15...a5 16.Bd3 g6 17.Qg4 a 4 18. b4 axb4 e.p. 19. Rxb4 Rxa2.

There is no way for white to play axb4 after black played axb4. White could only recapture with it is rook in b1

Christopher

Yes I saw that, but Sam is talking Bd3 rather than Rfd1.
15.....a5; 16.Bd3, g6; 17.Qg4, a4; 18.b4 is his line.

OK for who? Us? Yes it is because we then play Qe7. If then b4 we play Ra4!

[d] r2q1rk1/p2p2pp/2b1pb2/7Q/8/4B3/PPP1BPPP/1R3RK1 b

Ok this is the position if 15...a5 16.Bd3 g6 17.Qg4 a 4 18. b4 axb4 e.p. 19. Rxb4 Rxa2.

There is no way for white to play axb4 after black played axb4. White could only recapture with it is rook in b1

The en passant capture is made on b3, so the White a-pawn can recapture. I'm thinking that you're misunderstanding the en passant rule.
