It's not a good way just to take a C program and compile it with a C++ compiler. You _can_ use C++ just as a better C, and that is often a good idea for many kinds of projects. But you have to put some time into it, just as you've put some time into learning and using C. If you work two months on your program just doing what you normally do, but using a C++ compiler, you may find that suddenly the C++ compiler is faster for you than your C compiler. Because that is the environment you've been working and testing in. Whenever you've made some small decision about something because you got a 0.1% speedup, that might not be because what you wrote was better C or better chess programming, but simply that you wrote something that suited your C compiler better. If you really care about these tiny speed improvements (which is a very bad idea at this point, I think), and you want to use a C++ compiler for it's many advantages, I suggest that you work in that environment for some time before making a decision. If you learn to use C++ in the way it was meant (that doesn't necesarily mean object oriented, but C++ is _not_ C, it is very different), you will reap even more benefits than tiny temporary speed gains that will disappear anyway as you make your program more complex. You really can't "solve the speed issue" first and then go on doing everything else. You have to find a good design, and only when your program and design is mature, you can work on speed. __Using a profiler__. /David
