Let a + b = cNote that 5a - 4a = aNote that 5a - (2 + 2)a = a
Then 5a - (2 + 2)a + 5b - (2 + 2)b = 5c - (2 + 2)cRearranging,
5a + 5b - 5c = (2 + 2)a + (2 + 2)b - (2 + 2)c
5(a + b - c) = (2 + 2)(a + b - c)Cancelling the common factor (a + b - c), and removing the brackets as they are now redundant,
5 = 2 + 2
Hope this helps.
The fallacy is that if a+b=c, then a+b-c=0, so when you write
5(a + b - c) = (2 + 2)(a + b - c)"
what you are really saying is that 5 x 0 = (2+2) x 0, which is true, but you can't cancel the 0s to leave 5 = 2+2 because 5x0/0 does not equal 5 and (2+2)x0/0 does not equal (2+2).
This took about the same amount of time for me to solve as the chess puzzle.

@dsf001 I see now Kg5 is big blunder. Many Thx.
Hello and good morning. That was practice puzzle par excellence [pardon my bad French)!
but this puzzle will end up being a draw. so white cant win
That is an abstract way to equalise.
ur rating is 719. that is way abstract
Bit tricky once you get the first move the rest follows up easily
another queen sac
A Queen sacrifice, putting the Black King in check and threatening the Black Rook. Wunderbar!
That was cool. Not that obvious either.
Fortunately for Black the White Q sacrifice is accepted. Both first moves lead to the best outcome (draw) that either player can expect. Fun Puzzle, and it only took two tries to solve.

Had me stumped - Not used to playing for stalemate. Must look for alternatives for black.
