What is TRACE?

TRACE is a computer chess engine. It began in Nov 2002 as a Winboard compatible engine based on Tom Kerrigan's TSCP .
Her playing strength is ~2500 Elo.

Competitive highlights...

How do I play against it?

TRACE has a text interface only. She's designed to run under a graphical chess interface like Winboard or Arena.
To simplify things, you can download Winboard and TRACE in one handy installer package.

Well, for a very long time I've wanted to own a BEAUTIFUL wooden board and pieces. But not just any board...

I wanted one that would work directly with Arena or Fritz so I can play against TRACE and other chess engines.
Well, DGT have a 'bluetooth' version of their famous DGT Electronic board with full piece recognition.
These boards are a work of art. I just had to have one...

So, I looked around for potential suppliers and made enquiries. By far I was most impressed by Baron Turner who runs the
ChessBaron sites and settled on obtaining the board through him. He made absolutely sure that all went smoothly.
The board was shipped promptly from the UK to Australia and arrived in perfect condition a few days later.

Now, I despise advertising.... but in this case I really want give the ChessBaron site the highest recommendation. Thanks Baron!
And here's the board below... it actually looks even better in real life.

A little background... we are from Wollongong, Australia.

TRACE is an acronym for Trace & Ross' Australian Chess Engine....
Trace is my fun-loving friend and wife. Her encouragement made TRACE (the chess engine) possible.

I've been hooked on computer chess since 1983. The desire to write a chess program drove me to learn the art of computer programming and led
to a 25 year IT career. My first engines barely played chess at all. In fact, the first (written in GFABasic on an Atari ST) chose moves randomly
from a list of legal moves. TRACE is my first publicly available engine.
