18.....Qc7; 19.h4
How do we respond to that?

I believe that we should be looking for a way to neutralise (get it off the b1-h7 diagonal) or preferably swap off White's light squared bishop. It poses us the biggest danger. Just my opinion.

I would love to know how that would be possible when the most powerful chess engine in the world is unreleased and they don't have it.

Let's just agree to differ.

A possible alternative is18......Qe8 which covers any threats or shadow threats on the squares c6, e6 and g6. The queen could then come to f7 to either look at possibilities on the f-file or allow the f8 rook to move away.
If White plays 19.h4 we can play 19...Ra5 (20.Qb4, Rh5 and I think the rook is not only safe there, but plays a vital role in protecting against threats along that rank).

Qe7 or Qe8 both look feasible IMO. I'm a bit skeptical about Qc7. It takes the queen away from the kingside where it needs to defend at the moment, and doesn't seem to accomplish much. I guess I just don't see the point of the move, but I am a patzer after all.

Even if we neutralise threats on the kingside, the plan of b4 is still troublesome for us on the queenside. We're up against it here.

Should we be worried about 18....Qc7; 19. Bc5?
Example 19....Rfc8; 20.Bxg6, hg; 21.Qxg6+, Bg7; 22.Bd6 with Be5 and Rd3 looming?

I think that 18....Qe7 would be safer. I'll look more and post my vote later.
18....Qc7 19. Bc5? Bf3 is nice for us.
True. Missed that.
18...Qe7 is a bit risky anyway because of 19.Bd2 planning Bb4 prefaced by a3 first if necessary.
I like Qe7. It gives the option to play Qg7 and play Rfb8 to increase the pressure on b2.
Rb8 may not be best because b4 axb3/ cxb3 (an the the two passed pawns look dangerous). If we play Rfb8, white will have to recapture with axb3. In addition, Qe7 is rather flexible.

vote = Qe7

PS: In addition, at one point we may want to start moving our central pawns and Qe7 protects e6.

Qe8 does not make sense to me. You block both the rook and the queen in just to move it out of the way again?

I would prefer a direct Ra5 or even Qe7 to Qe8.

Qc7 is much more flexible than Qe7. It attacks more squares. It allows our rooks to work in tandem and gives them more freedom. It also gives the us the ability to defend both kingside and queenside. We will eventually move our central pawns so Qg7 is not an issue yet but will be possible when we do move them. Qc7 also allows our dark squared bishop more freedom to move. Qc7 allows us many more discovered attack options as well on the f and c files for example. I would rather protect/defend e6 with something lesser than the queen.

Qe7 is a claustrophobic move IMO. That is why I like Qc7 better.
