It is an interesting phenomonen! Good fundamental algorithm/poor optimisation is one probably the main cause, but here are some additional things I believe play a part (at least with my engine): - long time controls very much hide the bad time management by bodo - i believe my hashing replacement scheme is better than a lot of engines at my strength level, so if we play longer time controls, then the other engine's hash table can get saturated, causing a move ordering penalty. - my nps is not as high as a lot of other engines, so longer time controls lessen the chance of being many plies of search behind... - i use ETC and IID, and at my level, a lot of engines don't have these features which potentially (certainly do for me) make a difference at longer time controls. - weak evaluation of my engine compared to others of similar strength. the search saves me from many poor moves. Although this list is hardly conclusive, they are the main points which spring to my mind at the moment. I find it significant that they all seem directly related to a 'poor' job by the programmer.
