North's BIT means that he was thinking about doing something other than pass. This could only be double or 4♠.
We probably need to know a little bit more about North's bidding style. Would North routinely raise 1♠ with 3-card support and a 3 or 4 count?
It's kind of hard to think of too many hands that North could hold which would be thinking about penalising 4♥ but couldn't find a bid over 1♠. On that basis, I think the BIT likely suggests a really weak hand with 3-card or perhaps ♠10x which certainly makes 4♠ attractive by South. I think pass is a logical alternative for South at matchpoints as there are decent chances of beating 4♥ if partner just has one of the ♦K or ♣A.
I don't allow 4♠.
South perhaps dug his own grave by not bidding 4♠ the previosu round.
Completely disagree with this. Most of the time, I have 7 tricks in 4
♠ so it's cheaper than 4
♥ making at this vul. Is 4
♥ making, you'd be unlucky if it wasn't, but that is possible and also depends how little is required by the partnership to dredge up a response. The reason for not bidding 4
♠ last time is that if hearts are 2-2, there must be a decent chance of the bidding dying in 3
♠-2 or 3
♠x-1 vs -140, so at least have a go at finishing there. I think that since you protect on some pretty weak hands, the 4
♥ bidder has an opening hand to bid this at red and the only reason for this auction is that he has too many spades to X, a 3352 14 count with 5 bad diamonds would not be atypical.
If I had a singleton heart, I think I could bid 4
♠ with impunity as now partner can have say
♥QJ109 and be thinking about doubling. As it is, he only has 3 so this is difficult to envisage (although if I had a void in spades opposite I might think about doubling to prevent partner doing something stupid, although I might then realise that thinking then passing might dissuade an ethical partner from bidding 4
♠ on hands that should, so I might feel forced to X).
With the hand DBurn gave opposite, I think I'd X 4
♥. I've overstated my hand with the jump to 3
♠ and if I had the 2 minor suit Qs opposite I'd certainly expect to beat 4
♥ or be getting a horrible result anyway if I didn't. Partner is more likely to have 18 or 19 points than 13 the way I think.
