When S opened 1NT (15-17)and super-accepted with 3H over the transfer, GIB Blackwooded into slam. But when the opening bid was was 1C and the 1H response was raised to 4H - showing a balanced 18-19 - it passed. It also Blackwooded over a 3H invitational raise. It moved to slam on the weaker auctions, staying in game only on the strongest one.

I cannot read the full explanation of the 4♥ bid, as it is cut off. I am curious as to why the jump from 1♥ to 4♥ is referred to as a "double jump-raise."

I guess it would define a jump to 3S as a single jump raise.

The full explanation of 4♥, which none of us can see because of the bizarre system issue that cuts off South explanations internally, is almost certainly "Double jump raise -- 3+♣; 4+♥; 21- HCP; 22- total points", where the point counts are based on the limitations of South's opening bid.

 

Presumably, over partner's 1♥:

• 2♥ is a raise
  
• 3♥ is a jump raise
  
• 4♥ is a double jump raise
