Here the key moves involve the queen .The queen is moved to a4 for a white and a5 for a black. The best way to win is to perform some kind of double attack. This can be done by moving the white queen to a4. This will pose a threat to the black bishop which is stationed at b4. The queen can also attack the un castled black king. This will have a definite outcome. As a first step the queen is moved to a4 .The white queen is sure to attack the white bishop no matter how the black replies. Whenever the pawn on c2 makes an early move the queen has to make its move from a4 along the diagonal to reach d1. For a black queen the diagonal move is from a5 to d8. The queen can move to a4 any number of times swiping points along the 4th rank and a file. If the black’s sixth move take back the piece on f6, the diagonal a4 to e8 is opened unnecessarily. Black should recapture with the queen and not the knight.
Next the queen should win on b4 or c6.White wins with 6. Black can save its bishop by blocking on c6 with the knight. This will not definitely help because it is a mere substitution of a minor piece. This very rarely succeeds if c6 is weakened by b pawn advance. The black can make a mistake by pushing b7 to b6 thus developing the bishop to b4 which is again a blunder. Next the movement of queen from qa4 should force Nc6. If black blocks c6 with the knight the then white’s knight takes the black. While black wastes time in guarding b7, white is ready to castle. Black can save the bishop at b4 but on the condition that it must submit to a pin on c6 knight. White actually makes a mistake by taking the pawn on e5. Instead of this the white could have moved c2 to c3 opening new files for attack. After the bishop retreats, black has the movement of qa5 at its disposal. Now it seems that black has hung the e pawn and the white has taken it with the f3 knight. Immediate step is to clear the a5 –a8 diagonal for the queen. Thus the king is safer. Now it appears that the black’s knight can take the undefended white king’s pawn. In such case the diagonal a4 to e8 can be cleared by moving d4-d5. White can reply to this in many ways but nothing can be done to rescue the piece on g5. If white recaptures with the f3 knight black takes on c4 with the d5 pawn. Hence the white should abandon either the bishop on d3 or the knight on g5. Another way is to retreat the kingside knight to d2, breaking the pin on c3. But this fails developing the bishop to d3. Black removes the queen knight and acquires the d5 bishop by a queen check at a5. White can get out of check but cannot save the bishop. The black’s knight is minced by 5…Qa4+. This saves the king. Now the white forks the king and a6 knight by checking on a4 with the queen. White fires a queen at a4 and get two pieces for a rook. White’s e3 bishop can capture the rook but a queen check at a5 consigns it. At the end of tenth move white wins.
