According to chess laws, a piece that’s absolutely pinned to its king still retains its power to check the opponent’s king. There are good reasons for this rule, and yet in the end it’s only a matter of convention. There is in fact nothing inherently wrong or logically inconsistent with the converse notion, that a pinned unit loses its checking power. Suppose we apply such an unorthodox rule to chess – what are the consequences? In problem compositions, the realm of fairy chess deals with all kinds of rule modifications, and this particular condition is known as Superpins. It turns out that Superpins – seemingly a minor rule change – is quite profound in bringing about many curious and non-intuitive effects. Let’s consider a position that demonstrates some of the special tactics possible under this condition, before looking at two problems that showcase such ideas in striking ways.
