Please tell me what's meant by the emboldened part
The best innings you ever played? The Lord's Test in 1972, just because of the conditions and the situation of the game [Chappell scored 131 out of 308 to give Australia a narrow first-innings lead]. Technically and mentally it was as good as I'd played. The conditions were very much in favour of the bowlers.
Does it mean that was the best innings he ever played?
