Interpretation of WAC.epd

[Fguy64]

greetings

most positions in the WAC suite have the notation bm <whatever> after the position. I have assumed that bm means best move

some positions have two moves, for example the following line...

r1bqk2r/ppp1nppp/4p3/n5N1/2BPp3/P1P5/2P2PPP/R1BQK2R w KQkq - 0 1 bm Ba2 Nxf7; id WAC.022;

So how do I interpret the fact that there are two moves? Thanks.

p.s.

I have downloaded the WAC.epd from http://public.me.com/chessnotation

Not sure about it but I guess that it means that both moves are solution of the position.

That means there are 2 moves clearly stronger than other moves (and hard to find ).
