After the Andernach meeting of 1993, at which Andernach Chess was introduced, the BCPS Residential weekend in 1994 at Oxford saw John Rice running and judging a tourney for the new condition. Michael and I were happy to figure in the award with this reflexmate. In the threat and both variations White clears along a line to allow a black mate moving onto that line, such that White can't capture the checking piece because of self-check thanks to the Andernach condition.
