change scale factor
Marco sugestion, same bench
make effect larger by shifting scale factor down
change coefficients to 26  3 to make  effect larger ( 1 extra piece is at 44)

Conflicts:
	src/evaluate.cpp
shift scale up  ( 36 , 2). Count down start from 4 extra piecs at 60.
Final drop from last extra piece is from 48 to 32.
 shift more  up  ( 38 , 2). Count down start from 4 extra piecs at 62.
 Final drop from last extra piece is from 50 to 32.
Limit effect only to 2 last exchanges before transition to opposite bishop endgame
centering around original scaling factor
decrease penalty  for traded piece (40, 1)
Take 7 scaling + 2  (42, 1)
try penalty 3/2  (37 , 1.5)
Penalty 1/2 (43, 0.5)
Take 10  + 2
scaling of take7   - 1 (39, 1)
scaling of take7  +  1 (41, 1)
Limit take 7 to to extra exchanges
Limit take 7 to 1 extra exchange before transition to opposite bishop endgame
try take 7 only above 2 extra exchanges
46 when 3 pieces else 46
change scaling factor on piece removal as if exchange happened to make search more stable for ltc
