For once GIB lead from the strongest suit, and I played the Ten and played a ♣ to Ten (!), Queen and King.
Now GIB switched to ♦, where I would have been down on a ♠-continuation (Shows how important signaling is), and East went back to ♠
Now I know GIB will play highest affordable card but is the ♣T from T963? I doubted and played ♣A.
I gave up, not seeing the winning line (West is squeezed in 3 suits if I just continue ♣)
