This doesn't make sense to me. You would force to game, implying mild slam interest, but consider the hand too weak to invite game?
Not at all. This is not a strong splinter and does not imply slam interest, as I have 4
♣ as a weak splinter and a stronger hand with a shortage starts with 2NT and shows the club shortage on the second bid. That would imply slam interest or possible suitability. A weak splinter just describes the hand so that partner may go slam seeking if strong enough with no wasted clubs, or can make a judgement in a competitive situation. He knows I have less than game strength in terms of high cards.
Of course my bids are based on an unlimited 1
♠ open, and if I played a limited spade I may well have different methods.
If I did not have 2 strengths of splinters, then this hand warrants a game invitational bid, such as a limit raise, but for me a splinter shows this hand, while a limit raise implies a bit more strength and less distribution. Sometimes the splinter may take you too high, but other times it helps to have the distinction. (I don't have 3
♣ available for a mini-splinter.)
