North probably has a quality check about its hearts- I count nearly 9TPs but they are a terrible evaluation (counting a honour singleton twice in the opponents suit)- you should have expected that and your hand is 19HCP of appalling shape (your K♠is worthless as fitting with North which absolutely need to have a chance at game) - I wouldn't want to come in there.
