Checkers Puzzle #2

Difficult

Number of solvers so far: 0

Red to play and draw.

In all of these checker puzzles,
Red gets kinged when reaching
the bottom row.

Checkers Puzzle #3

Difficult

Number of solvers so far: 0

Red to play and remove all of Black's stones
in 9 moves  (5 of red, 4 of black).


Note:

If Red were to move to the square marked "X",
he wouldn't gain a triple jump; only a double
jump. The rule is that you don't continue to
jump if you become a king in the middle of the
sequence (English and American rules).

Checkers Puzzle #1

Easy

Number of solvers so far: 0

Red to play and win.

Which checker should he use to
make the double threat? Or should
he make a different move?

Checkers Puzzle #4

Very Difficult

Number of solvers so far: 0

What were the last ten moves?

Red has just moved. It was the only legal move
he could have made. The same is true of the
nine moves before that.

In other words: Find the position 10 moves ago
(5 red, 5 black), such that each and every move
was forced, thus this is the only position that
could have occurred.

By the way, Red's 6^th move back (the 11^th move
back) should have gone for the kinging, not for
the double-jump.

Checkers Puzzle #5

Very Difficult

Number of solvers so far: 0

A Missing Piece!    == Note: Black always goes first ==

Red: "We're not playing well this evening."
Black: "True. Let's leave it as is and come back and finish
the game tomorrow."

Next day, they found a note from the cleaning person:
"I accidentally knocked one piece on the floor and I don't know
which square it was on. The checker box was empty so I put
it in there. Sorry"

1. What is the color of the missing piece?
2. Which square should it be on?
3. Which square was it on at the beginning of the game?
4. Whose move is it?
5. What was the last move?

6. After restoring the piece, and assuming "very good" (not necessarily perfect) play, the game should be:

        a) a probable black win         b) a probable red win         c) about even

7. Again, restoring and assuming "very good" play: in the next 8 moves (4 of each side), how many pieces will be captured?

        a) none         b) 1 or 2         c) 3 or 4         d) 5 or 6         e) 7 or 8         f ) 9 or 10
