I disagree that history tables hardly works.

Tscp has history tables and no killer moves and it has clearly better order of
moves than 50%.

I bet that if you remove history tables from tscp you will find that the history
is very important for it.

It is better to start with one thing and not with many things because many
things is a sure way for bugs.
The way to go is to add one thing and test if it is better.
