2D is positive response(one K at least) which deny good 5+card suit (2 of AKQ), 4D splinter

a) Any opinion about what went wrong on this auction?
b) Your minimum value for the 4D splinter call? Is 3 card support acceptable?
c) Please suggest a reasonable auction to reach the proper contract.

a) North can't make a splinter and then decide to pass 4♥. Once S rebid 2♥ N should drive to slam unless they are off 2 quick cashers. He should start by setting trump with 3H which invites slam and initiates cue bidding. S should now cue 3♠ and N can ask for keycards.knowing the opps can't cash 2 spades off the top.

I don't think South underbid. He has a minimum 2♣ and the splinter is not helpful to him.

North has a monster and can't possibly stop short of slam.

Hi,

a) North has to do more, he has at least a Ace more, actually AQ, he has to move over 4H.
b) yes, 3 cards are enough, you may or may not like it after 1M opening, but in the given seq.,
you have a 9 card fit, and space is limited, and after showing the support via a simple raise,
you dont have any room left for a splinter.
c) either North continues over the 4H bid, or chooses 3H, which should be forcing and showing SI,
2D was generating a GF, and the splinter consumes a lot of space, so you should avoid it, if
you are unsure, if passing the neg. is a good idea. Given Norths hand, he should feel unconfortable,
if he intends always to move, than go for the splinter.

With kind regards
Marlowe
