Alan Brown's view:

E 1♠
W 2♣ - no need to rush, E will certainly bid again. With a combined count of 30+ HCP we are possibly in the slam zone
E 2♥
W Right. Partner is 5 - 4 in the majors. He did not jump in ♥ so they are at best K high. He has not bid NT so he has nothing in ♦. And speaking of diamonds we really need the final contract to be with West to protect that suit from the lead. So I will just bid 3N.

For the more advanced, I think West's bid should be 5N. E can now bid 6 happily with that AK of ♣ that partner does not know about.
