Signs

Keep signs simple. You can use a simple numbers system. That is, how many signs will you give before a specific cut-off gesture. By counting the number of signs before the cut-off, the player knows the play. For example:
2 signs = take (two...take)
3 signs = hit and run (three words in hit and run)
4 signs = bunt (four letters in bunt)
5 signs = steal (five letters in steal)
