Subject: To NON-believers in EGTB benefits... (some engines benefit greatly...)

Author: enrico carrisco

Date: 19:42:02 11/20/05

Let's take a simple KRK ending...

[D]8/2k5/8/3R4/8/8/5K2/8 w - - 0 1

Now let's run it through some of our favorite new and old engines without using
any egtb's... (i.e. engine's knowledge of the ending only.)

8/2k5/8/3R4/8/8/5K2/8 w - - 0 1
