Bringer can use tablebases. I suggest to use at least the 4-piece endgame
tables, which are ~30 MB. If you don't want to download that much, there's also
a free generater program available, i.e. from

ftp://ftp.cis.uab.edu/pub/hyatt/TB/

The Hiarcs 7.32 had a generator too, with Windows GUI.

In a large rating list (BfF-Liste by CSS-Magazine) which consists of games
played on PCs ranging from Duron 900 MHz to Dual-P3/1 GHz at blitz to medium
time controls, Bringer 1.8 is listed with 2.350 (80 games). For comparison, on
that list Tiger 14 has 2.610 and Crafty 18.10 has 2.475; Bringer ranks 20...30
elo below Comet and AnMon engines.

In my old test suite with mostly easy positions (and a few difficult ones),
Bringer 1.8 solved more than some top engines! - But in general, it was somewhat
slower than those.

26.Rxh5

Bringer 1.8 needed 2:11 on P3/700 to find this, which is a good result.
