Here is a hand link. Hope this works!

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
