leave (something) on the table
v. phr.— «In recent years the biggest fortunes Wall Street has handed out have gone to enterprising merchants rather than to software stars on gene-splicing geniuses. Look outside the top ten and you will see First Boston and Donaldson, Lufkin & Jenrette. So don’t worry about the dealmakers. They always seem to leave something on the table for themselves.» —“Who’s Where In The Stock Market” Forbes Jan. 14, 1985. (source: Double-Tongued Dictionary)
