But I have also seen that CM takes up to >11min for a move. I admit I am a bit confused and not 100% convinced that the >time management with Gunnar malins adapter or with the King iworks correctly. Couldn't you enable the log feature in the adapter and send the log to me. In your sample earlier in this thread the engine have the same color that it get with the new command (black) so there could be another bug than this black/white commands that I mention in another thread. If you want to look for bug yourself you could check that the engine receives the 'level 40 120 0' command at the start of the game and 'time 720000' or close to this before the first move it should calculate on. The adapter have to figur out a level command to send to the engine because this information is only inderect in the uci-protocol so there is room for bugs here. I could enable black/white command but as I mention earlier I have to do some tests so this would be done right when you analyze games too. In normal games there isn't much to test but when the gui-start to go backwards in the game as it does when you analyze, it send the hole game to the engine, but I convert this to send undo commands to the engine so that hashtables are kept to benefit from this analyzing method. To send new or setboard and feed the needed moves will most certainly break this benefit for many engines. There is a propose for this in the protocol but as I understand, this is to fix some old engines behavior e.g. send white-time-black. It could be that this is the best method anyway. I could also do an extra 'undo' so the engine would act like it does in normal games. Beside this there don't need to be a bug because The King used 3 min to move in a 120 min/40 move game. (120/40=3) If it was confused the calculation would not be so different. It still should get this 120/40 level but would be told on the first move after book that it has only 114 min for the rest of the moves. On the next move it would be back on track again.
