Hello!
While working on my chess engine I've come across two problems which I dont know
how to deal with correctly:
1. After retrieving a hash entry, can I do the following:
if (tt_flag == UBOUND) beta = MIN(beta, tt_merit);
It has worked for me fine, but is in my opinion theoretically unsound.
2. How to deal with a result from a node where alpha and beta have collided? Ths
happens rarely, but can happen due to altering of bounds because of a hash
entry. What can I do if i want to store the result from such a node? It is
neither a LBOUND nor a UBOUND, right?
I hope some of the more experienced chess programmers can help me with these...
thanks
