So you could claim the draw even if the opponent has enough material to mate?
Yes, assuming that a win is incredibly unlikely.
E.g., suppose you have KQ vs. KR, the side with the queen can claim a draw by insufficient winning chances, likewise for KQ vs. KRP, KQ vs. KQ, KQ vs. KRB, KR vs. KR, (provided there are no immediate wins), etc.
What does reasonable play mean?
TD's discretion here. Also a time delay (Bronstein) clock may be provided in some situations; I think the delay is set to 5 seconds. Also TD's discretion.
I think the USCF rule is whether a class C player could lose the position, but I'm not sure.
Also is two nights and a king vs. king considered mating material? The win cannot be forced but a mate is possible against poor play.
This is an interesting question and I'm not sure what the right ruling is. I saw a similar case at a Chicago Open between GMs where a KB vs. KBP ending came up (where the pawn was a rook pawn). The side with KBP was playing for a win and flagged, the KB side attempted to claim a win. His argument was that although a king & bishop can't mate by itself, it can against a rook pawn. The TD ruled this a draw at the time, I wasn't sure if that was the correct ruling or not.
I would certainly attempt to claim a win if I had the two knights and my opponent flagged, who knows whether that would get granted or not. I think the side with two knights has a better claim than the side with the KB vs. KBP, but not sure either of them would be ruled a win.
These would be draws by insufficient winning chances if you claim before you flag.
