Rook PSQT Tuned This patch uses about half the changes of the SPSA tuning run: http://tests.stockfishchess.org/tests/view/5dba93d30ebc5925b64ed3bf About a month ago, xoto10's patch raised the mg value of the third rank center files from -1 to 7 to encourage rook lifts to the third rank. About three days later, Rocky's patch lowered this value from 7 to 3. This patch raises that again from 3 to 12 and ends up greater than the original rook lift patch.
