Pitching To Chilled Wort Or Let Warm Up?

[pb unleaded]

I have two cubes of "yes chill" ales which were in the fridge for two weeks. I am now ready to ferment both.
Should I take them out of the fridge and let them warm up overnight or...

...can I just pitch cold and let warm up in fermenters? The yeast slurries are also chilled.

I am thinking of pitching one cold and warming the other.

Any thoughts?

thanks

My understanding is that the pitching temp should aim to avoid thermal shock to the yeast. If the yeast were at 18-20 and the brew at 2 then it might be better to warm. However if both are chilled then I'd just pitch and let them warm up together.

I could be wrong - my instinct mainly at play here.
