This is the shortest way to victory!
After this combination, the whites have one rook and two pawns against a knight and a bishop.
Capablanca has knew that these two minor pieces can not fight with equal rook and two pawns such as these two pawns are thru!
Please enjoy the whole game that needs no more comment!

If you play with the whites how you proceed now? This task is very difficult and the most important here is your idea for the white\'s attack and/or your first move!
Good luck!

The task (2):
---------------
White to move and win!

Congratulations kai2011!
Those are the right solutions to our tasks!
I will now give a more detailed the answer.
------------------------------------------
These are the answers to the tasks:
---------------------------------------
And two tasks - (and the task (1)
(after: (17...Rf8) and), and the task (2)(after: 34...Kc8) are from same game.
This is the game:
Anatoly Karpov (1:0) Gyula Sax
Linares 1983

The task (1):
-------------
1.(18.)Rd5! - Karpov has needed from the victory in this game!
This sacrifice of quality does not guarantee the victory\'s white, but gives a very strong attack against the black king in the center and a perspective position.

And the blacks will exchange the officers and ensure safe the black boxes for their king.
------------------------------------------
Note:

2...(19...)Rd8 is a natural move, but the best move is: 2...(19...)Qb4 (This is Anatoly Karpov\'s comment!)
