I am a little confused about how to pronounce the character Ч. From what I've read, it's supposed to have a 'ch' sound. In oчень, it does! But in Что, it seems to take on a 'sh' sound, which is represented by another character in Russian.
Am I just mishearing the pronunciation, or...? Maybe it is a 'ch' sound and it's difficult to hear?

If not, what differentiates the way you use it?
