The (2) means the first two ply-1 moves are searched one at a time, before the parallel search can actually start searching ply-1 moves in parallel. I do this when there is a reasonable chance that the next iteration might "find a better move". as indicated by significant node counts for two or more ply-1 moves at the previous search. > >> >>I suspect many programs will find/play b6 here... >> >> >> >> >>>[Event "Cadaqués 2001"] >>>[Site "?"] >>>[Date "2001.01.19"] >>>[Round "19"] >>>[White "Deep Fritz"] >>>[Black "Junior 6.0"] >>>[Result "1-0"] >>>[ECO "B85"] >>>[PlyCount "166"] >>>[EventDate "2001.01.??"] >>> >>>1. e4 c5 2.
