I've been tring to understand TT for a long time but with only little success !
I saw different algorithms that got me even more confused.
Generally I need a document that explains the TT interaction with the alpha-beta
(as detailed as possible)
moreover, i have some questions about TT usage and algorithm:
1) Do I use the values stored in the TT when i'm scanning with Iterative Deeping
? (example: values from depth 4 are not accurate (and even misleading) in depth
5 (and so on...)
2) How do i use the Upper/Lower Bounds and when.
the lines : if lowerbound >= beta return lowerbound
else break;
confuse me - why this condition is checked - the values should be correct in
all the cases because a rescan will generate the same cutoffs ...
Thank you in advance - take it as a challenge (to explain as good as possible)
