OK another one of my marginal reverse hands.
Shouldn't 3H be prioritized over showing diamond fit, when the suit is this long and good?
I realize on this hand 6d makes and 6H doesn't, but slam is kind of a horrible contract and 4H is by far the safest game contract. Might be tough to construct good rules here because with some stronger hands with 6 cd hearts, Ace empty, or AKxxxx type of hands, and diamond fit, want to move towards diamond slam and might want to ruff out hearts or have other source of tricks, where the diamond raise would be preferred. So maybe low priority to fix this. I'd generally want to show hearts with only 4 cd diamond fit, and good suit solidity playable opposite stiff, unless maybe have ace headed suit and slam values. Similar if club fit, it wants to raise clubs at too high priority when holding good 6/7+ major. I'd like to rebid 3M and then maybe pull 3nt to 4m depending on the hand, rather than raise m and never show the really long M.
Now my opponent OTOH not wanting to make a light reverse, instead tried 1c-1h-1s. Then North bid 2d 4th suit forcing, and raised 2nt to 3nt, never bothering to show hearts a 2nd time! He luckily escaped a black suit lead. Surely Northbot on this auction should bid hearts at least a 2nd time, if not a third?
