Seven Triple Double Checks

I have recently enhanced the chess search engine I write in my spare time with double-check detection. To test it, I made the engine ingest 5.82 million unique over-the-board games from the 15 Million chess games database kept up to date until 2015. 0.85% of these games turned out to contain double checks. More precisely, there are:

  • 48261 games with one double check,
  • 1184 games with two double checks,
  • 76 games with three double checks,
  • 3 games with four double checks,
  • 3 games with five double checks.

I naively expected that the games with many double checks would shine with mate combinations, yet as a rule they just end with perpetual check, plain and double in turn. Much more spectacular and much less frequent are games where double checks occur in a row. It took my engine 0.75 and 0.55 seconds, respectively, to answer the queries

???++ K?? ???++

and

???++ K?? ???##

with 129 pairs and 6 triplets of consecutive double checks. I show the triplets below. They all follow the same pattern where rook blocks and discovers the diagonals of a bishop pair. Incidentally, among chess problems, a mate in 13 by Stojnić and Babić (The Problemist, 2004) sports as many as 13 consecutive double checks based on the same idea.

The seventh confirmed occurrence of a triple double check comes from Renaud and Kahn’s book The Art of Checkmate. The initial moves of the game are lost.
