Several late raids looked likely but both times as they worked the Force tacklers back and forth across the field, the Chiefs made the crucial gaffe. The final move had Aaron Cruden snaking promisingly downfield but towards the sideline where his reverse pass was shelled.
Without one desperate ankletap from Tom Marshall which tipped Nick Cummins out near the corner and the work of men like Brodie Retallick and Liam Messam, the defeat would have been more decisive.
It will put more tension into their campaign as they head with a growing injury list for their next encounter with the Bulls. The Chiefs pulled gritty wins together to open the tournament and need to reclaim that strength and some cutting edge in South Africa.
