Consecutive checks

Just a thought I had - greatest number of consecutive checks possible in a real game. This is my first effort, any improvements?

In the game Britton-Crouch ( P&D Knights, London 1984 ) black made 43 checks in succession, a record at that time.

See " The even more complete chess addict " (1993) by Mike Fox and Richard James, pages 240 and 241, moves nr 46 - 90.

RomyGer, the maker meant that all checks were answered by checks, not one side giving checks, but both.

Hang on, my postion isn´t really legal, hehe...

Well, this is how far I got anyway.

You guys are a looooooong way off the 53 on Tim Krabbe's site, lol

(legal position, promoted pieces allowed)

Do you happen to have the link to there?

You should post a warning below links like that!

My head hurts now.

That sure is a nice sequence.

Wow...

f5 pawn is so important...

Here's the current record of 54 by A. Khanyan.

Is that a legal position in post 13?

Per Krabbe's site, it is. Counting promoted pieces, white has promoted 7 and black has promoted 4. This leaves 3 black pawns and the Bc8 to sacrifice to white pawns. So, something like this can explain the promotions.
