obsidian12 bug?

[Uri Blass]

I adjudicated the game to be a draw after Obsidian refused to move for many minutes(it is supposed to move after 131072 nodes)
both engines used 1 mbyte hash tables.

The time control that banksia saved in the pgn is wrong and the correct time control is 131072 nodes per move for white and 262144 nodes per move for black.

Note that I hesitated if to adjudicate it to be a draw or a win for black but decided to adjudicate it as a draw(by the chess rules it should be a win for black if black win on time because white can help black to mate but black cannot win on time when there is no time control and only fixed nodes per move and maybe obsidian could play after many hours so it is not fair to decide that it lost on time)
