Locked Triple
A Locked Triple is a Naked Triple where all 3 cells are locked in a single intersection.
Because the intersection is part of 2 houses, the Locked Triple can cause eliminations in both of them. If there are only eliminations in one of these houses, the same eliminations can also be made with the Locked Candidates technique.
Locked Triples are easy to spot, because the 3 cells are all next to each other.
