<p><strong><span style="color:#090;">Update: Tarrasch Toy Engine 0.903</span></strong><br />
The engine is a part of the Tarrasch Chess GUI<br />
Look for &quot;Alternative Download Procedure for Experts only &quot;<br />
and download the exe files only. One of them is the toy engine.<br />
- Tarrasch toy engine generally reports on progress in more standards compliant way;<br />
- It continually reports on progress in go infinite and go commands and reports <br />
  useful information after a stop command.<br />
- It measures time and nodes from the start of the go or go infinite command, <br />
  not from the start of a particular level<br />
- It also uses one less thread, and writes to stdout in the root thread, this <br />
  means ChessBase 9 sees its kibitz output immediately, not after a timeout.<br />
- Up until now Tarrasch toy engine did a very stupid thing. It would try to create the file <br />
  'C:\Documents and Settings\Bill\My Documents\Chess\wx\release\toy.log' and log info to it<br />
- That was pretty bad, but worse was that on machines other than mine it would <br />
  invariably fail (the directory wouldn't exist) and it would then spew the <br />
  log info to stdout instead<br />
- This would ensure that the engine wouldn't work with other GUIs (the only <br />
  surprising thing is that it did work with my GUI!)<br />
- Needless to say, all this stupid behaviour is now fixed. <br />
