I think the game that is most closely associated with CoB is Macao, probably because it also relies on dice in a clever way. Certainly of the three games you list, Macao is the closest to CoB in weight and harshness. I agree with Carl that Macao plays fine with 2 (it's probably a little better with more, but it's perfectly good with just 2 players).Of course, you could always go with Roma, which also uses dice in a nice way and is strictly a two-player game!
Feld. So many good choices...
