Solution to Warm-up Puzzle:

Suppose the row player puts a 2 on the bottom row (replacing the C), yielding:

5 7 6 1 4 9 2 3 8
8 4 9 3 7 2 5 1 6
3 2 1 8 6 5 9 7 4
4 6 3 7 9 1 8 5 2
1 5 8 6 2 4 7 9 3
7 9 2 5 3 8 4 6 1
2 1 4 9 5 6 3 8 7
9 8 7 4 1 3 6 A 5
6 3 5 B 8 7 1 2 9

Then the column player has to move where the A is. The Sudoku rules would suggest replacing the A by a 4 to satisfy the constraints within the lower right-hand box. But that would violate the row constraint, because there is already a 4 in that row.
