Adjusted Score - what would be led?
This is the hand:
N E S W
P 1H 3C X
P P XX 4H Passed out
EW Make 4H +1, S leading SA and then a spade ruff.
3C is Ghestem, but is not alerted by N (nor indeed to do they at any point tell the opposition this).
EW claim they would have bid to 6H had they known what the 3C bid was. I concurred with this (although on reflection I may have given a proportion as 6H and a proportion as 4H+1).
The issue comes on the play of 6H. S is adamant that he will lead A and another spade just as he did against 4H. I did not accept that, since 6H is a different contract to 4H, and I asked him why he would do that rather than a safer lead of, say, KD (which gives EW 12 or 13 tricks). He repeated his response about 4H, and when I asked him again he threw his teddies out of the pram.
So my questions are:
1) Am I right that the lead against 6H might be different than against 4H?
2) When deciding what S might lead, do I do a split on the basis of how likely a lead is, or do I take the least advantageous "normal lead", or something else?
3) Am I missing something completely obvious here?
I accept that the lead would be affected by the auction, but as this is an adjusted score, there is no auction to consider. Perhaps I should have taken them through how the auction would have gone and then asked him to justify his lead?
