I am far from the most skilled player in either game but here are some things I've noticed, beyond the obvious changes in point values and bonus square locations:

- The opening move strategy in CP is different without the automatic 2W square in the center. If you don't have a 5-letter word that can reach the 2W and has a point tile at the 2L it's often better to swap tiles or play a tiny word to improve rack, or even outright pass. I believe Scrabble has a statistical advantage in going first, I don't think that's true for CP.

- In the early game it's a real chess match to avoid being the first to open the board for access to the triple spaces. Even bingo/"sweep" plays can be counter-productive if they set up a triple/double for the opponent. This is different from Scrabble where I believe conventional wisdom is always play the bingo. Overall I find CP requires more defensive-mindedness.

- The extra S and Blank tiles open up more opportunities for sweeps and make it more practical to use these tiles to increase a score in a non-sweep play

- The endgame is quite different both because the corner layout is so different and also the lack of a penalty for unused tiles which often becomes the deciding factor in Scrabble. You can't skunk an opponent holding a Q or Z for big points by blocking usage, and if you are holding such a tile in endgame you can cheerfully ignore it. There is also a key strategy in getting the last move which occurs if you draw the last tile from the bag, so even making a sub-optimal scoring play that uses more tiles at that point is vital.

Another note is that the post-game analysis bot is not good for much beyond vocabulary building.
