i think the inferrer has a bug, at least when it comes to exchanges. this interesting position led me to run the inferrer myself and examine the log file. my understanding is the inferrer compares the static equity of the inferred move to the top move, and if they are within some margin, the rack producing the inferred move is considered possible. here all of the inferred moves should be exchange 1s, but if i am reading the log file correctly, the inferred moves are often one-tile non-exchange plays
