Subject: two ECM98 questions

Author: martin fierz

i'm using ECM98 for testing purposes, and i found two positions with alternate
solutions (i think):

ECM.018 bm Nxd6

[D]r3rbk1/1pq2ppp/2ppbnn1/p3p3/P1PPN3/BP1BPN1P/2Q2PP1/R2R2K1 w - - 0 1

intended solution: 1.Nxd6 Bxd6 2.Bxd6 Qxd6 3.dxe5 +-
alternate solution: 1.Bxd6 Bxd6 2.Nxd6 transposes



ECM.614 bm Qxf7+

[D]5r2/pp1RRrk1/4Qq1p/1PP3p1/8/4B3/1b3P1P/6K1 w - - 0 1

intended solution: 1.Qxf7+ Rxf7 2.Rxf7+ Qxf7 3.c6! bc6 4.bc6 Be5 5.Bd4! +-
alternate solution: 1.Rxf7 Rxf7 2.Qxf7+ Qxf7 transposes

am i missing something? is anybody still maintaining ECM98 officially? did i
download an old version of this? is there a newer version? questions, questions
:-)

i got my version of ECM98 on scott gasch's monsoon site:
