IID margin reduced to 128 Change the internal iterative deepening margin from +256 to +128. Passed STC: LLR: 3.26 (-2.94,2.94) [0.00,5.00] Total: 22006 W: 4646 L: 4400 D: 12960 http://tests.stockfishchess.org/tests/view/5ab54a240ebc590295d8847d Passed LTC: LLR: 2.96 (-2.94,2.94) [0.00,4.00] Total: 46665 W: 7187 L: 6898 D: 32580 http://tests.stockfishchess.org/tests/view/5ab5ba690ebc590295d884b4 Possible work in this area after this change: • Reduce even more the margin? • Try to do IID for smaller depths too?
