Abstract
We report on experience related to the online training for the Italian and International Olympiads in Informatics (IOI). We developed an interactive online system, integrating the programming problems and the grading system used in several major programming contests, including the IOI. The system has been used in three distinct contexts: training students for the Italian Olympiads in Informatics (OII), training teachers in order to be able to assist students for the OII, and training the Italian team for the IOI. We also present the initial design of an extension deemed to provide trainees with a personalized support to skills’ enhancement on contest problems.
The title is a tribute to David Mamet’s book Three Uses of the Knife: On the Nature and Purpose of Drama.

To check the correctness of some problems is enough to check that the output produced by the student is the same as the output produced by the correct solution; in other cases, usually when there is more than a unique solution for a problem, like finding a path in a graph under some constraint, it is necessary to write a checker code that verifies the solution proposed for the given input.
