Say you decide to lead the T from AT9xx against a NT contract. Dummy comes down with 3 small. Partner overtakes with the J and declarer plays the K. What would you place partner with?

Would it matter if your agreements are modified slightly from standard so that from a suit headed by T9 you would lead the 9 instead?

Since he is unblocking, I would place my partner with QJx or Jx, or, worst case, just J. Hopefully we play some sort of Smith so that it clarifies the situation.

Well, what if you are not playing Smith?

Also, you would play the same even in the second case?

You don't know if partner has the queen or not. He has to play the jack from Jx to unblock for this exact scenario.

If you have no way of signalling later whether he has the queen or not, you have to just play bridge and figure out what to play. If you are playing imps and your only hope of beating the contract is him having QJ, just go for it. If you have some other play, then try to figure out which is your best shot. All you know is that partner might or might not have QJx, QJ, Jx, or stiff J

What JLOGIC said.

If you play strong 10s (so the 10 promises at least one higher honour) then partner can play low safely from QJx, so the Jack is either Jx, J or QJ. (With Qx partner has to play the q to unblock). You still won't know if partner has QJx or declarer has KQJ, in that case.

If you don't play strong 10s, then partner has to play an honour from QJx in case declarer has the AK, otherwise the suit gets blocked.

Then I recommend playing Smith so that you have a way to solve these problems.
