用三步克制约中炮的凶焰,历史很长,而在三步虎的基础上配之以列炮,却是七十年代中期的新装备,到了八十年代才屡屡逞威。这是三步虎布局构思的升华和飞跃。如果说老式三步虎在抗击中炮上常显力量不足的话,而三步虎转列炮显然是增加了对抗性,给后手布局带来了蓬勃的生机。 It has a long history of restraining the fierce flame of the medium-sized gun in three steps. In the three-step tiger, it was equipped with a series of guns, but it was a new piece of equipment in the mid-1970s. This is the sublimation and leap of the three-step tiger layout concept. If the old three-step tiger in the fight against the gun often lacked strength, then the three-step tiger turnaround gun is obviously an increase of confrontation, posterior layout has brought a vibrant life.
