   Hello from Yefim!
   Reminder: I am writing a book about Math and Chess where some specific
positions are being used.
   The following 9 positions are needed to be checked on legality.

rB2k1B1/1Bp5/ppn1p3/1B3p2/2p2p2/1P2P3/8/R3K1b1 w Qq - 0 1
rB2k1B1/1Bp5/ppn1P3/1B1prp2/2pP1P2/1P2N3/8/R3K1b1 w Qq - 0 1
rB2k1B1/1Bp5/ppn1p3/1B1pRp2/2pP1p2/1P2P3/8/R3K1b1 w Qq - 0 1
rB2k1B1/1Bp5/ppn1P3/1B1prp2/2pP1P2/1P2N3/2P5/Rb2K1b1 w Qq - 0 1
rB2k1B1/1Bp5/ppn1n3/1B1pRp2/2pP1P2/1P2P3/2P5/Rb2K1b1 w Qq - 0 1

rB2k1B1/1Bp5/ppn1n3/1B1pRp2/2pP1P2/PP2P3/2P5/Rbb1K1b1 w Qq - 0 1
rB2k1B1/1Bp5/ppn1n3/1B1pRp2/2Pp1p2/PP2P3/2P5/RBb1K1b1 w Qq - 0 1

   Upon a positive answer I will tell you properties of these positions and 
possibly
give you the similar interesting problem, which I could not solve.
  Thank you in advance. 09/08/2004 Yefim T.
