5 card majors, strong NT, MPs.
I lost the first seven tricks, and a club when the finesse failed.
After partner's 2
♥ response, I had a think and decided that bidding 2NT, showing a 12-14 HCP balanced hand with a spade stop is a more descriptive bid than raising hearts. Completely wrong here. Was my reasoning that bad?
As others have said, not bidding 3H was terrible--you must support with support. That said, pard should not have passed 2NT--he should have bid 3H, on the premise that you should have a doubleton heart on this auction. That bid wouldn't be forcing.
I see this all the time, pard makes a subminimum bid and then tries to compensate for it later in the auction. Best course would be a negative double followed by a heart bid. Shows exactly what he has.

IMO AL78 was unlucky. Over South's (1♠), I rank
1. 3♥ = FIT 5+ ♥ 4 + ♣ -- only by agreement
2. Double = NEG As suggested by Crapdown4; intending to persist with a non-forcing 3♥ later.
3. 2♥ = F/1 (F/G in 2/1). IMO an overbid.
After 1♣ (1♠) 2♥ I rank...
1. 4♥ = NAT WEAK, playing 2/1.
2. 2N = NAT Seems OK to me.
3. 3♥ = NAT N/F (if 2!H isn't F/G).
