Should East play partner not to have signaled by dropping the K under the A with KJTx or not to have signaled by dropping the J under the A with JT7x? IMO, the latter is far more likely After partner played the 8 and 9, the jack, ten and 7 are of equal rank....and you did lead the 6. Partner knows you can afford to play the jack from JT76 or the king from KJT6, but you could also hold KJ76(x) or KT76(x), from which holdings you'd follow with the 7 (or x).
