Hey everyone,
Should I allow Null Moves in the LMR section of the search, or is this too drastic/inaccurate/dangerous ?
Thanks
Laurie

Most that I have looked at do it everywhere.

Since in the LMR part of the search, 98% of the time you're going to fail low this node.
Since a fail low in this node is a fail high in the child node, and null move pruning accelerates the fail high, null move is very beneficial.

Should I allow LMR within NULL move search, or is this too drastic/inaccurate/dangerous ?

Both are generally defined as recursive, so if you use one within the other, it works both ways.
