Yup - playing udca, 2 will be the card to show count No, you missed the point. It would be a disaster if partner played you for a doubleton club. This is the problem with playing count. If you play attitude here, you only encourage with a doubleton and discourage with more than a doubleton. Partner is very, very rarely going to need to know whether you have 3 or 4 clubs, but he will almost always need to know if you have 2 or 4. This ambiguity is just not necessary, and it's going to cost a lot when partner guesses wrong. If you play attitude, you get the benefit of being able to show the only count relevant to partner without any ambiguity.
