Checkmate with 2 Knights

Knights working together

Another interesting Checkmate theme is two knights working together to deliver checkmate! The knights work really well together, especially when they are on different colored squares around the enemy king.

Lets look at some examples from real class player's chess games, taken from my Tactics Time database...

Solution

Seize the outpost K5 with your knight, and you can go to sleep. Checkmate will come by itself. - Savielly Tartakower

Here Black can deliver checkmate with 19...Nf2# The king is trapped by his own pieces. The pawn on d3 does a great job of holding up the powerful knight on c2, and removes the escape square on e2. Note that black didn't just make a greedy move like Nxa1 winning the rook, but finds the best move, which ends the game.

Dead of Knight

Here is another position where there are two knights handing out a final death blow to the enemy king. This time it is white dishing out the punishment.

Here 17. Ng6# is the winning move.

Note how the knights are on different colored squares in the checkmate. If they were on the same color, they would not be covering as many squares. Having your knights on different colored squares can help maximize the amount of space your pieces are covering.

One good trick to remember is that a knight always attacks a different color than it sits on.

So if the knight sits on a light square - such as g6, it will be attacking a dark square, such as e7.

A knight will always move from one color to another as well (a corollary of the above rule). So if the knight currently sits on a light square, the next square it moves to will be a dark square.

You can also think of it like this: A knight will be able to attack the same color that it is currently sitting on. So the white knight on h4 is currently sitting on a dark square. That means the next move it makes will be attacking a dark square. Since the black king is on a dark square, it has the potential to be attacked by either knight in the starting position, because they are both currently sitting on dark squares (h4 and d6).

These little tricks can help make your calculations faster.

Play around with the knights on an empty board to practice. Michael de la Maza calls these "knight sight" drills, and are like practicing layups in basketball.

Sharpen the Saw

Here with 11. Nb5# the white knight jumps into b5 screaming "Yippy Kay Aye Mr. Falcon!" delivering a nice open field QB sac.

These patterns should be starting to look familiar at this point. The knights are on opposite colors, and supported by a pawn.

  • The first knight cuts off the exit points, stalemating the king (or cutting off most of the escape squares)
  • The second knight comes in to hand out mate.

Even though all these positions are similar, it is good to study these types of positions over and over, taking in the slight differences, and really drilling the patterns into your brain.

You want to have these positions drilled into your head, so you can't NOT see them. They just pop out at you.

I like this quote so much, that it is my slogan on my chess website. I have THOUSANDS of these types of problems in my database, which I spent hundreds of hours gathering, and running computer analysis on.

I also have a FREE tactics newsletter, which I send out about every other day, with a new tactics problem for you to solve to help "sharpen the saw" as Stephen Covey would say.

You can sign up for the newsletter on my website, and see samples as well.

Pure mate

Pure as Silk

This is a really fun position!

I like this one because the knights are truly doing it by themselves. Not even a pawn to give them backup support!

Here 10. Nc7# delivers a pure mate, where each square is only covered once and only once.

I hope that you enjoyed these tactics. There is one more part coming, which deals with a special case of the two knight checkmate - Legal's mate!

Happy Tactics!
