- 4th best except for Hx(x). - Highest affordable card from bad suits for attitude. - Partner's suit (natural 1 ![]() - Power lead: K for count or unblock. - Std. honor leads: T from AT9(+)/KT9(+), J from AJT(+)/KJT(+), Q from KQx(+), A from AKx(+). - Occ. incorrect honor or spot. Vs. Suit: - 3rd from even, low from odd. - Partner's suit: High from xxx or xxxx if raised, others the same. - K for count or unblock, and A or Q for attitude (at 5+ levels). - Std. hornor leads (A from AK, J from AJT/KJT). - Occ. incorrect honor or spot.

Priority: UD Attitude -> UD Count or Suit Preference, vary with logic.
UD discard: low encourage, high discourage. Lots of suit preference when applicable (e.g. in trumps). |
