The game is famous for the double exchange sacrifice used by Topalov, the first one being prepared before the actual game with his second Cheparinov. Serious home preparation indeed !

August 2007 Hints

Hints ( Aug 07)
Puzzle 1: The Black queen is too far away to defend. Try to open more lines !
Puzzle 2: The bishop in b2 is powerful. How to extend its range ?
Puzzle 3: Morphy sensed that Black's lack of coordination could be exploited. Try to get closer to the king.
Puzzle 4: The rooks are active, but can you bring another piece into the action ?
Puzzle 5: The first 2 moves are logical ( attacking the white king) but the third one is about geometry ( there's an elegant switchback move to be found ).
Puzzle 6: Try to break through the defenses by destroying them.
Puzzle 7: It's time to strike, as all your pieces are centralized. The White Queen is not protected!
Puzzle 8: Tactical motives help strategical goals : here the goal is to promote the b pawn.
Puzzle 9 :Was it safe for White to bring his king so far into the enemy's territory ?
Puzzle 10: Opposite bishops help the attacking side. Try to sacrifice pieces for a larger pay-back.

July07 puzzles Hints

Here are hints if you need a little help to solve July puzzles.

Position 1: You need to focus on attacking the Black king and for that remove something which keeps him safe.

Position 2: The knight in f6 is defending h7. You can introduce a deviation and bring more forces into the attack.

Position 3: Don't hesitate to consider all candidate moves. A radical breaktrough is needed !

Position 4 : The Black Queen will soon be overloaded. Try to think in terms of a double attack.

Position 5 : The Black Queen has lots of things to do. Can you take advantage of that fact ?

Position 6 : You need to increase the pressure and get closer to the King. Sometimes quiet moves introduce strong threats.

Position 7 : The White king is in danger obviously. And the bishop c4 could soon be hanging as well.

Position 8: Overloading again. Can you combine threats against the King and the Queen ?

Position 9: White is defending. In particular, one of his pieces is awkwardly placed. Try to win a piece.

Position 10: Think of all candidate moves, and try to think of a temporary piece sacrifice. Attacking the King will bring you victory!
