The not making progress rule occurs quite often in chess tournaments where you often get down to having to complete you moves in 15 minutes and the player with more time just tries to run the clock down. I don’t think the rule is so applicable for correspondence chess or sites like Brainking.
Justaminute: Correct it is not.. what concerns me most are situations in games that require time to break through b/c of moving pieces from one side of the board to the other. With being conspicuous ( due to blindness of the pieces) you cannot expect to be forced to reveal a piece b/c your limited on time. ( not reveal through actual recon but through redirection.
