sprt @ 15+0.05 th 1 Opponent Bishop long-term mobility is penalized by same color pawns. This test considers our wedges (example c3-d4-e3) as an additional long term structural hurdle (for example, for a Bg7). Based on an idea by Fauzi.

sprt @ 15+0.05 th 1 Try to retire see_sign by adding a depth argument to the signature of see, at which the swap algorithm is stopped. If see_sign(m) >= 0 then see(m, 2) would be also >= 0 but the inverse is not true. Let's see how far this go. One could then tune the swap depth for the specific tuning purposes.
