Hadar Shemesh breaks down the CH sound in English. It's a stop plus a fricative, not just SH. Skip the T-like closure and you say "share" instead of "chair".
chair, share. Can you hear the difference? Chair, share. Cash, catch. The CH is an affricate, which means you start with a stop sound, the T sound, and then you release it to a fricative, which is the SH sound. There are some speakers that struggle with this combination, and they might replace CH, chair, with chair. Just the sh sound. This is not enough because if you drop the t part of the chair, you are going to be saying a different word. Chair, chair, chair, chair, chair.
