Go up one level in this thread


First you said...

"No way, this can be fixed easily without any decrease in strength."

Then when I ask "What would be an easy way to fix it without decreasing
strength?" you said...

"You certainly can not solve the problem generally without decreasing strength
but it is at least possible to prevent the engines from playing this beyond
stupid move." You then said that preventing such moves might indirectly increase
strength.

These statements appear to be mutually exclusive, or maybe you just changed your
mind? If you did change your mind, I can certainly appreciate why...if it was
easy to fix without any decrease in strength, the Shredder or Hydra team would
probably have already done it.

Seems like the easiest way to deal with this would be by tailoring the book to
play ONLY open positions against human players. In other words, have the
computer use ANTI-HUMAN play before the human can use anti-computer strategies.
The operator should be able to choose what book the machine plays before the
game begins, just a human chooses his opening based on his opponent.

However, if you're looking for a set of "chess general heuristics" that provide
the best move in any circumstance, then I guess you wouldn't want to exclude the
possibility of such positions. I guess your design depends on your
goals...desire to win the most games or desire to advance the art.
