I think batting under pressure, with tail-enders that requires guarding your shots, bring the best out of Riyad. He has been very effective in this role and as said before, somehow knows how to get the best out of his partner as well.
Despite his lack of form in the NCL this season, out of the 3 test innings so far, he scored half century in 2 and was doing very well on the other innings until he ran out of partner and decided to have a big heave.
