I want to know whether my guitar teacher will win a public competition next weekend, decided by a jury. Since he is a teacher, he could be associated with the 9th house, but because he is my teacher, I take him as belonging to the 7th house. The 7th house is in Aries, therefore the significator of my teacher is Mars, which is in the 5th house in Aquarius.

As this horary is in elective-type question, since there is a jury making a decision, I assign the Moon to the voters, as is customary in electional-style horaries. The Moon is in the 6th house in Pisces.
I then need to identify my teacher’s adversaries. Since he is the 7th house, his opponents are the 7th derived from the 7th, that is, the radical 1st house, which is in Libra. The significator of his opponents is Venus, which is in the 6th house in Pisces, exalted and with triplicity in Water, therefore very strong. By contrast, Mars is peregrine in Aquarius, without relevant essential dignities. This already suggests a clear advantage for the adversaries. The fact that Venus is conjuncting the North Node also benefits them.
The most decisive factor is that the Moon applies by conjunction to Venus, indicating that the jury goes towards the significator of the opponents. The judgement is straightforward. My teacher will lose, unfortunately.
