 Bohemian Meredith without any white Pawns. The tries 1. Qf6?, Bd6? fail to 1.. Rc5. So the hidden key threatens 2. Qd4+, but also controls c5. On 1.. Rb3 2. Bd7+ Ka3 there is the pin mate 3. Bd6# (2.. Kb4 3. Qc5#). This also shows why 1. Qg1? does not work. On 1.. Rb6 2. Qd4+, Ka5(b5) 3. Rc5# again a pin mate with an exchange of the pinning and mating pieces (wR, wB). Some side variations are 1.. Rxc8(Rab8), Rc5, Bd3(a2) 2. Qxa7+, QxR, Q(x)a2+ On other moves of bRb4 it follows 2. Bd7+ Rb5(Kb4) 3. Qd4#. Quite a challenge to solve and also of thematical interest.
František Matoušek (*17.1.1879 in Praha, +21.2.1956 in Praha) Czech composer. "Matoušek is of course a member of the Bohemian chess problem school. For the amateur interested in the problems of Matoušek, V.Pachman has written an anthology of 100 threemovers "Problémový šach  Výběr 100 trojtahových úloh Fratiška Matouška" which is available online. A picture of him and his obituary can be found on page 58 of "Československý šach 1956" (due to Václav Kotěšovec)."
