White to play and win
We all love underdogs. David vs Goliath, Rocky vs Ivan Drago (Rocky IV), Nelson Mandela, Gandhi etc. There is something magical when the underdog beat the top dog, especially so when the odds are overwhelmingly against the underdogs.
Take a look at above position. This is the position in which a lowly pawn able to beats the raging rook and it come with the good story.
Above position first appeared in the chess column of 'Weekly Citizen', a Glasgow paper on 4th May 1895 initially thought to be a beautiful draw with a solution that runs
7.Qc4 stalemate, draw.
But hold on! It just getting better!
Two weeks later one of the member of Glasgow Club, the Reverend Saavedra discovered a win for white!
1. c7 Rd6
7.Kb3 winning either black rook or king!
Instead of promoting a pawn to a queen and draw, white can promote a pawn to a rook and win!
In such a simple position surprisingly there are lots of play. Queening threats, under promotion, stalemate threat, domination and ofcourse underdog (pawn) beat the top dog (rook)!.
This position therefore has been named 'Saavedra Position'
But, is our friend Fritz agreed with above line?
Unfortunately, Fritz believe above line is not a best defense for black. Fritz like this line better (but nevertheless still a win for white)
4.c8=Q and now it is a battle between a queen and a rook which is with exact defense, should be difficult for white to win.
I hate engine!
To see Saavedra in action, you may see Svidler vs Topalov(Linares 2006) game. Beautiful and highly imaginative endgame play by Svidler, sacrificing a whole rook to reach Saavedra like manouvre, not to be out done a few moves later Topa sacrifice his rook hoping to reach a stalemate defence. It didn't work.
