Zalokotsky theme

H#3+: In the first phase, some piece visits in succession three squares. In another phase, another or the same piece also visits the same three squares in succession, but in the opposite order.

According to some sources, a reduced theme form is allowed, in which two thematic moves and two thematic squares are sufficient.
