Yes, the contract is not what even E expected. It must be considered that if the pair reaches the slam when it has a double fit, it is advisable to choose the 4-4 fit because with the other suit, losers can be discarded. Perhaps it also depends a little on the Acol system (which I don't apply) because E has a hand of 12 points:2♣ does this show directly? But maybe we meet on 3♦ which should be UCB indicating the excellent support for ♣ contract that E would have played also having the King protected on the exit of N. But having W a 5-4-2-2 and however, being at the top of the second range it was clearer to bid 4♦(=almost game) which would probably have been followed by the cue of 4♥(=12/+ points) which could direct the auction.

2♣ the way we play Acol shows 9+ points with 5 or 10+ with 4, Acol people vary exactly how much it shows but it usually around this (in very old fashioned Acol could be a little less).

With all my partners a 2/1 shows a good 9+HCP.

I thought so (9 and not 12 p. as i use to bid) and that's why i' ve talked in that way.

This one is easier for us, where 2♣ establishes a game force and does not promise 5 cards or deny any degree of spades support.
Now we can play a 3♦ cue as a stop ask and simply raise clubs here:
-- 1♠
2♣ (2♦) 3♣
3♠ 4♣
4♦ 4♠ [♠!♥]
5♥ [odd keycards, ♥♥] 5♠
p

Although in one eccentric partnership this would probably go:
-- 1NT
2♣ 2♠[5]
4♠ p

We play a 2/1 gf system, so we use the cuebid to say:
“hey, i have Axx, Kxx or Qxx, you should bid 3NT with atleast Ax, Kx, Qx so we have 2 stops”
So, similar to the bidding above, ours would go:
1♠-2♣ (2♦)
3♣-3♠
4♣*-4♦
4♠**-4NT***
5♣+-5♦++
5♠+++-6♣++++
* slam intrest
** denies ♥ stop
*** 6RKC
+ 1/4
++ key queens?
+++ second step, 1 queen
++++ opener has 5=x=x=4, 6♣ with 4-4 is the best contract
