[quote] But the main point here is that "the horizon effect" is something the computer search actively "uses" to hide things that are unpleasant. It is not something that "just happens" because it can't search deep enough. [/quote] Any threat too! If search doesnt like the place it is in, just threaten to take a piece which must then evade. So between 1. checks [already covered by check extension] and 2. captures[ covered if using recap ext] _AND_ 3. simple threat moves [which it turns out are so numerous its hard to extend all them without explosion] This horizon effect is _all over the tree_! This is exactly why I think it is important to find a way of identifying when the search may be _decieving itself' and 'using' this When might this phenomena be more or less likely, with reference to, say, eg alpha/beta bounds or draft or ply?
