Passing the opponents' support redouble is apparently illegal for GIB. (It will in fact bid 2♥ with a void in hearts if you give it 6070 and force this auction, though the opponents' sequence wouldn't occur).

You are kind :) Change the vulnerability so N/S are red, and you are looking at -1100/-1400 in a ♥ contract. When North responds 2♥ here, you do not expect a hand with no honor card and a doubleton ♥ suit. I would be raising as South.

WTP??? 2♥ => 2 hearts. Really, if GIB wanted to show 4 hearts, GIB would have bid 4♥. 5 hearts would be shown by 5♥. GIB believes in bidding what it has.
