Simple razoring: depth 1 only, no distinction between PV / NonPV
We simplify the razoring logic by applying it to all nodes at depth 1 only.
An added advantage is that only one razor margin is needed now, and we treat
PV and Non-PV nodes in the same manner.
How to continue?
- There may be some conditions in which depth 2 razoring is beneficial.
- We can see whether the razor margin can be tuned, perhaps even with a
different value for PV nodes.
- Perhaps we can unify the treatment of PV and Non-PV nodes in other parts
of the search as well.
STC:
LLR: 2.96 (-2.94,2.94) [-3.00,1.00]

LTC:
LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 62670 W: 10749 L: 10697 D: 41224 Elo +0.29

In addition, we ran a fixed LTC test against a similar patch which also
passed SPRT [-3, 1]:
ELO: 0.23 +-2.1 (95%) LOS: 58.6%
Total: 36412 W: 6168 L: 6144 D: 24100 Elo +0.23
http://tests.stockfishchess.org/tests/view/5b6e83940ebc5902bdba1485
We are opting for this patch as the more logical and simple of the two,
and it appears to be no less strong. Thanks in particular to @DU-jdto
for input into this patch.
