  1. I think any system which doesn't allow you to show immediate support for pard's major with 4-5 trumps is highly questionable. Here, pard didn't know there were any spades at all until 6S. The power of splinters here is dramatic, eg 1S 3C (or 1S 4C) allows the extreme wasted values to be identified at a low level.

    1. I agree. One of the best advances in modern bidding is a convention like Jacoby 2NT a game force support raise or splinters establishing an immediate fit.

      When I first learnt I was taught to make a delayed game raise with a game going hand and support. The trouble is that there are too many auctions where the auction gets murky.

      6S can nearly be made here. If trumps were two-two and declarer guessed to finesse in clubs and pitch a diamond then ruffing one diamond and one club in the west hand and playing ace and another spade would leave south on play with the hK to give declarer a ruff sluff. Of course an awake defender would see this coming and play the hK under the ace so that north could take two heart tricks. In turn declarer can make this difficult for the defender by playing the hA as early as possible in the play before south knows what is going on.
