But still I have one question. I am a little bit intrigated by your last sentence. If you could reformulate or simply explain it, it will be nice. "Extensions" are usually used to keep a program from running out of search depth. My understanding was (probably very wrong) that extension are some kind of addition search done for few next plys deep. If this is really so, how can extension "keep program from running out of search depth"? Thank you in advance! Leonid.
