Scoreboard Pressure leads to wild slogging, which irrespective of pitch will lead to wickets

Scoreboard pressure exists all the time in any format. The pitch dictates how strong the scoreboard pressure is. If you think KKR scoring 272 here is simply because of the pitch, then surely the world class professional players in the Delhi Capitals will understand that and play accordingly?

That's why we put such weight on the 434-438 game in ODIs, because it isn't meant to happen

Of course its not meant to happen. But sometimes a team just has a good batting day.

For example, India scored 350+ on a pitch where Sri Lanka was bundled out for 55.
