5S
I decided to disturb and once again it paid off.
After some auction, GIB stopped at 5S.
I led a heart, and tried ♠8 when GIB finessed trump, as the high spot might create something.
N played back a heart, and because of the "Cappelletti 2H“, GIB played me for 1552 with singleton ♠8, and finessed ♠6 on the way back! So my ♠7 won an unexpected trick and gave N a heart ruff to blow the 32 pointer slammish 5S for two down.
