Subject: Authors of Kaissa on quiscence search

There are a lot of interesting ideas in a book by the authors of Kaissa.
They offer to include in quiscence some, but not all checks. The classes of
checks that they offer + some my additions.

1. Checks with capture
2. Checks with threat to take some piece with see>0.
3. Discovered checks
4. Checks with rook or queen stands close to king with see>=0.
5. +1 additional check in each branch of quiescence.

Using this classes of checks can provide limited tree growth with very good
tactical results.

I need your results to compare.
