OK, but I don't think you played with MTD(f) long enough to make it work really well. You cannot simply replace PVS with MTD(f) and expect that your engine will play as well as or better than before; it takes a long time to learn all the tricks. Many techniques which work well with PVS are less effective with MTD(f), and the same holds true in the opposite direction. This, of course, makes it very difficult to make an objective comparison of the two algorithms. Only 8 plies in 1 minute seems quite bad -- it happens very rarely for Gothmog, I think. >How much RAM does a Palm have? Most current models have between 8 MB and 64 MB. But the RAM is also used for permanent storage; there is no hard disk. All your programs and data are stored in RAM. There are also some rather strict limitations about how much memory each application is allowed to use, but I think this situation will change in Palm OS 6 (which will be ready before my program is finished). But nevertheless, the total size of my code and data should probably not exceed 400 kB. Tord
