I think that it will be hard to find more than 100 legal move in games(you can construct position with more than 200 moves but if you talk about positions from real games then my experience is that even more than 80 is very rare). constructing a position with more than 19 mates in 1 is easy [D]k7/2PPPPPP/7K/2Q5/2Q5/2Q5/6R1/1R5B w - - 0 1 Here is first position that I composed and I am sure it is easy to compose a better example.
