This game of mine is one of the finest I have played. This games reminds me of GM Alexander Niktin who once said that the queen is the weakest piece.

The Classic Ruy Lopez

The Ruy Lopez is an opening which teaches all the aspects of chess in one single game like maintaining the center, development, direct and indirect pinning, gaining a tempo, closing the centre and attacking the king, wing attack. maneuvering the knights, greek gift, sacrificing at the king to open up and many more. Hence experience in this opening helps to learn chess in many ways.

Taming The Knights!!

It is not a matter of coincidence that all chess world champions were fond of bishops.But there were players who were fond of knights. Like Mikhail Chigorin, Nimzowitch,Morozevitch and many more. Having looking at Chigorin games I now have a fondness on knights. Here is a game in which I very much concentrated on knight moves.

Long Live The King's Gambit!!

If there is any beautiful opening system then that must be Kings Gambit. Here is one game I played recently at LSS. The positions coming out upto move 11 is out of the understanding of all top engines. May be my opponent relied on hardware and I on brainware so escaped with a win in equal position. Its one of the Hardest Game I have ever played.

Pawn Power In Correspondence Chess

Once Philidor said that pawns are the soul of chess. But now a days in the computer era it seems pieces play more in coresspondence games than paws. Still pawn movements in game can be decisive. Sometimes in the middle game you have to think of what pawn position are you going to get after the major and minor pieces including the king position which in turn decides the outcome of the game. Here is an example of that where my opponent played actively with pawns until the last moment where I used the pawn power to conclude the game.
