Hi Marc!

You may, but in this particular case I'm afraid I don't have a very interesting answer.
I remember reading you on this forum stating that one can make Glaurung stronger in tactical test suite but with the side-effect of making it weaker in eng-eng matches. Could you tell me how to? (I'm interested in solving tactical test suite).
I don't recall exactly what I wrote, but I think I was speaking in very general terms, and not just about my own program. Everybody who has been doing chess programming for a while has experienced that the parameter settings which maximizes the scores on tactical test suites are rarely optimal for practical playing strength. Therefore, I and most other programmers never tune our programs for tactical test suites, and consequently we don't know what parameter settings perform best in test suites.
It is therefore quite likely that you know more than me about how to maximize Glaurung's scores in tactical test suites.
I'm asking because I realized that when I increase "style" parameters like aggressiness, developpment etc. results are better at quick time control, but for tougher problems requiring long searches (like 10min or more on a PIV 2.0), the boosted Glaurung doesn't do as well, the default settings are doing better.
This is interesting and somewhat surprising, and I am not sure why it happens.
So I'm looking for parameters that would do good tactically at long time control ( I don't expect you to have an answer for that).
Unfortunately, I don't.
Good luck with the new version,
Thanks!
