it may depend on what you know about partner's habits but i think the 
only possible cause for partner's pass over a relay is that he has 
forgotten, and so UI equals AI.
on another side i also think the main problem is not UI but MI: had rho 
been correctly informed about your pair's agreement about 2C, he might 
surely have considered another call than 2D.
