0 or 2 Higher Leads
0 or 2 Higher Leads are used when holding interior honor sequences headed by the jack or ten: AJTx, KJTx, AT9x, KT9x, QT9x, etc. Normally, the top interior card from these sequences is led:
- KJTx
- KT9x
- QT9x
- KJTx
- KT9x
- QT9x
Other Considerations
- 0 or 2 higher leads apply on opening leads as well as subsequent new suit leads.
- 0 or 2 higher leads only apply when leading from a tenace. From an unbroken sequences such as QJTx, for example, the top card should be led.
- 0 or 2 higher leads do not apply when leading from AJTx or AT9x against a suit contract. In those situations, the standard lead is the ace.
Expert Opinion
In his great book "How to Defend a Bridge Hand", the late Bill Root (expert player and writer) strongly endorsed f 0 or 2 higher leads, saying:-
"This convention should be used by all competent partnerships. The advantage of Zero or Two Higher is the card you lead makes it easier for your partner to figure out whether you are leading the top of a sequence or from an inside sequence." 1
-
"This is very good against weak players as you give your partner a useful piece of information. Meanwhile, a poor declarer won't appreciate the inferences available. On the contrary, against good players, this is a horrible method. It gives way too much of an advantage to a decent declarer.
"I'll let you in on a Bergen-Cohen secret: We used to play this 10/9 0 or 2 method against weak players, but standard against good players. We had 2 different convention cards depending on who our match that day was against. Thank goodness, our opponents never knew our criteria!" 2
