Subject: Check extensions (again)

Author: milix

Hello
I had read many posts about check extensions but still have some questions.
Assuming the case that incheck() situations always extendend with 1 ply (no
tricks):

1. When incheck() and only one legal move do we extend again (meaning we extend
with two-plies)?

2. In the new extended search if we find a checking move, do we extend (the
already extended search) again?

3. When (and how) do we determine if a move is already extended; is this
relevant to (2)?

4. Do we have to disable extensions when in Internal Iterative Deepening?

TIA
