[Retros] 50 moves FIDE rule

[TregerYefim at aol.com]

Hello!

>From math point of view the FIDE rule about 50-moves draw is not perfect. It 

was implied that only pawn moves and captures radically change motion of the 
game not giving any progress. But it is not true. There are positions, in which 
NOT pawn moves and captures also radically change a course of actions. For 
example, the position below has 5 such halfes-moves.

4k3/4P3/4P3/8/8/8/pPpPpPpP/1QrRrRK1 w - - 0 1
