Thanks, Christophe! I didn't really think that you would do that. Congratulations with your new program! Everything seems to be working fine on my Celeron. I changed the lay-out a bit, shrunk the moves-list a little so that the histogram could be put under it. Couldn't find that at first, I believe I used 'Arrange Icons' to locate it and other windows that are sometimes minimized. The colour of the board is now dark green for the dark squares and a specially composed honey yellow for the light squares which makes the board stand out a little more. The statistics window I usually make a lot larger after some time so that I can copy the variations in a Wordpad document. What I liked a lot was the possibility of copying the game.pgn to clipboard which is directy accessible from ECTool. In ECTool I can then switch on a Rebel engine or two as well with the full game details directly copied. Easy! Then I copy the ECTool board as a bitmap to the Wordpad document too, full color, no chess-book can match that! Or from Rebel Tiger there is a little graphical board font too which can be used as a little diagram. Now all I need is grandmaster insight to go with the analysis! I believe I did run into Uri's 'infinite time' bug, at least after about 7 hours the NPS counter and the total NPS right at the bottom of Tiger's window were showing negative numbers then. Maybe the engine was still working because the NPS was still changing. I don't really know, Tiger was already eighteen plies deep at the time! Try that with Q5T, there there seems to be a natural limit of seventeen plies, maybe the extensions of Deeper Search grow too big then. But I didn't have enough patience to see if the move that Tiger was contemplating at the time would change anymore as an indication that the engine was still running. What I did notice is that Tiger is sometimes very modest in asking CPU time, with normal engine priority. I'm using Windows 98 Second Edition. There was already a DOS box with Century 2.0 running when I started up Tiger 13 which went very well. The NPS is normally around 110000 but did not go much higher than 10000 now as Rebel was first. After closing down the Rebel engine in ECTool the NPS is climbing with about 20 nodes per second, per second (NPSPS or something like that). As I am writing this it is up to about 50000 and climbing about 10 positions per second each second. Maybe it is more aggressive in asking CPU time when playing a game, at the moment it is in analysis mode and infinite time. But I thought that for people playing Blitz on the Internet maybe it might be an idea to keep an eye on the NPS counter, to see if Windows is giving Tiger enough time and if the 'Engine Priority' should not be changed to "high" then if necessary in View -> Properties -> Chess Engine -> Advanced. Just some observations, thanks Christophe for your programming! Eelco
