play hard ball

A good negotiator knows when to play hard ball and when to give in.

一个出色的谈判家知道什么时候应该强硬，什么时候应该让步。

And it tells other producers, Iran in particular, that the Saudis are willing to play hard ball in the rush for Asia's market share.

而且是在告诉其他产油国，尤其是伊朗，沙特愿意为争夺亚洲市场份额打一场硬仗。

I have also witnessed a player reacting to his opponent's international and illegal blocking by deliberately hitting him with the ball as hard as he could during the course of play.

我还曾经亲眼目睹，一名球员在比赛过程中为了应对对手的全面违规封堵，故意用球狠狠打他。
