We investigate the problem of finding an unknown leaf in a full binary tree, allowing the questioner to ask only queries whether the hidden leaf is in a given full subtree and assuming that one of the opponent's answers may be erroneous. We give the worst-case minimal number of queries sufficient to perform this search and provide an optimal algorithm.
