A recent tuning session by Jerry Donald Watson suggested that the value for the pawns on the fifth rank in the connected[] array were a little bit too high in master. We lower here this value from 75 to 65. STC: LLR: 2.95 (-2.94,2.94) [0.00,4.00] Total: 27399 W: 5646 L: 5384 D: 16369 http://tests.stockfishchess.org/tests/view/5aea17c50ebc5902a1bed396 LTC: LLR: 3.66 (-2.94,2.94) [0.00,4.00] Total: 95590 W: 14529 L: 14062 D: 66999 http://tests.stockfishchess.org/tests/view/5aea34a40ebc5902a104ebe5 Closes official-stockfish/Stockfish#1580 Bench: 5186783
