I meant to the fact that hiarcs does not finish the iteration of moves when it fails low but does another iteration. I claimed that Junior usually finish the iteration of moves before playing. stuart replied Hiarcs too but if it is losing it just goes on thinking... He meant that finising the iteration of moves is not enough after failing low and it does another iteration. I replied that hiarcs is the only program that I know that does it. My opinion is that the idea of doing another iteration after failing low may be a good idea only when you have many moves to the time control. If you have 110 minutes for moves 15-40 and you fail low then using 30 minutes for one move because of doing another iteration is not a disaster and may be productive but later in the game it is not a good idea.
