Subject: The difference between short and long time controls

In a thread above Christophe repeated his statement, that there can not be a
difference in _relative_ playing strength for short or longer time controls.

I disagree and may present at least a hint, that this might not be true for
certain engines:

Gerhard Sonnabend performed this test:

<pre>
Chess Tiger 15.0(CB) "Normal" vs WIN-Rebel 12 (Test12a)



Stellung No.    1-10      11-20      21-30      31-40      41-50      51-60
61-70      71-80       Total    (+  1/2 -)

  5min/game  13.0- 7.0  10.5- 9.5  13.5- 6.5  14.5- 5.5  16.5- 3.5  15.0- 5.0
  0          0       83.0-37.0  (68-30-22)

 10min/game  15.5- 4.5  13.5- 6.5  13.0- 7.0  13.5- 6.5  11.5- 8.5  13.0- 7.0
  0          0       80.0-40.0  (63-34-23)

 30min/game  11.0- 9.0  12.5- 7.5  10.0-10.0   9.5-10.5  13.0- 7.0  12.5- 7.5
  0          0       68.5-51.5  (48-41-31)

120min/game  10.5- 9.5  10.5- 9.5  12.5- 7.5  11.5- 8.5  11.0- 9.0   9.5-10.5
  0          0       65.5-54.5  (41-49-30)

</pre>

I do not know if there is a statistical sound difference, but at least it looks
like Rebel performs better at longer time controls.

regards Joachim
