I think we are talking at cross purposes here Gentlemen. As a Player, not a Programmer, I use Chess engines as a 'Tool', to learn about a position. The Analysis Module can generate a "Variation" OR, many Main Lines, Simultaneously. You, are 'locking' it to a single 'variation'. As such, it will stay with that variation, and go as deeply as the time you allow, or until it recognizes it is not as good as another line. You imply, and IMO mislead, by stating that it doesn't 'see' or find another move, or may never find a certain move. This is not correct! The Engine is searching many of the most promising "Candidate" moves simultaneously. This is exactly what a Player wants to know. Increase the lines to 3, or 4 and you'll see the Best continuations, and how the evals change with time. It matters not a whit if Crafty or Shredder when locked to a single 'variation' takes hours to search to a Depth of 16 ply, and then changes it's mind, when by Opening it to 3 Main Lines, you see that it DOES find and eval 11. h5 in less than 2 minutes, then promotes it to the PV. Now what is important here? To sit and wait for hours, or search and find the most promising Candidate moves almost immediately? Does it make any sense to 'test' an engines response time, or to gain information about the position? Hmmmmm? CY
