Good test position. At least engines which do not use egtb in the search, should probably have code for that type of position, or a "no progress" rule. Engines quickly reach depths of 20+ in this position. With a material balance of +4 and no progress at all after 20 plies, it is most probably a dead draw. I think that could be a "safe" rule, if the opponent has only the king (maybe even 10 plies are enough already, in those cases). Yours truly Paul J. Sacral
