Simplify the "overload" condition This is a follow-up of the previous pull request (#1686) by Miguel. We simplify the "Overload" bonus condition by re-using the "weak" variable, which captures well the essence of the overload condition. This may also be a small speed optimization because the weak variable is in a register at this point of the code. http://tests.stockfishchess.org/tests/view/5b527b440ebc5902bdb7f7db LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 10925 W: 2517 L: 2374 D: 6034 http://tests.stockfishchess.org/tests/view/5b527f930ebc5902bdb7f883 LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 15569 W: 2697 L: 2568 D: 10304 Closes https://github.com/official-stockfish/Stockfish/pull/1687 Bench: 5010472
