Subject: no transposition tables

Author: John Coffey

Let us say that I have a system with not much RAM, like the Gameboys that I
program.  Transposition tables are out of the question.   The Gameboy Advanced
(16 mhz risc processor) has 1/4 meg available as an option that can be placed on
an external cartridge, but I figure that is not enough to do anything.

Here is what I am thinking for a chess program:  Iterative iterative deeping.
If I have a 7 play search, and I am at ply 4 deep, it would still do a 1 ply
followed by a 2 ply folled by 3 ply to finish that branch of the tree.

Of course I would give priority to checks and some captures.

Would it help?
