Over 1♦-1♥ you will have a 1N response
Over 2♦-2♥-2♠ you will have a 3♥ response

2♣ Crowhurst
4♣ cue (4♦ by opener would be cue not LT for us, over which I'll bid 4♥)

I presume partner has the miracle Ax(x), KJx, AKJ10x, xx(x) for 12 off the top for this post to be made

Using Crowhurst do you assume 1N is 12-16? I was playing Acol and defending on this occasion , but hadn't discussed this.

Over 1N I bid 2♦ artificial GF looking for direction (hopefully a hearts raise).
Over 3♥ I bid 4♣ looking for spades control.

Did he bypass a diamond control or are we assuming diamond control from the opening?

Pretty standard NA auction starts 1NT-2♣; 2♦ (I assume, if 2♥ different)-3♠ (4♠, 5♥, GF). Any bid that isn't 3NT will be a cue agreeing hearts.

Does the 3♠ bid say anything about shape or honour concentration?
If not opener will raise to 4♥.

In which case 32♥
What is the advantage of Crowhurst versus 2♠ as 5♥4♠ GF?

3♥ over 2♣ would be 17-19 3♥, 2♥ would be 15-16. =3♥ means exactly 3 hearts if that confused you
