Chess Strategies
Some of my favorite strategies... depends on the actual position, but I'll bite:
1.Giving the opponent a space advantage so I can play against overextended pawns and punch out of the cramp with at least equality.
2.Giving up a pawn to open lines.
3.Placing pawns on the color of my opponent's bishop and/or the opposite of mine to both activate mine and restrict his.
4.Attacking a c6-d5 pawn chain with a b-pawn to weaken the c6 pawn, and preventing his c5 break before that.
5.Leaving a piece en prise for mobility and a strong initiative, usually the opponent has to return material. Kotov's advice in Think Like a Grandmaster where he says he asks himself what can he leave en prise was worth the price of the book I think.
6.queen on g3 and bishop on b2 provoking weaknesses in black's kingside.
7.Putting a knight on e4 as black in the Queen's Indian and playing f5-Nbd7-Nf6 and really clamping down on the light squares, but this isn't always possible or viable and not played in a systemic fashion (calculate and think, c6 can be weak in the queen's indian if you aren't careful)
8.Win the bishop pair and open the position.
I'll post a game I played as black involving the four knights, I played the opening badly though thinking I could go by Ruy Lopez principles:
Been looking more into the four knights and remembered there is something called the Haloween Gambit, with instead 4.Nxe5. It looks very weird but the idea is to follow up with moves like d4 after the knight recaptures to harrass the knights and gain a lead in deveopement. I wouldn't try it in standard games, more a blitz or bullet game opening but it's something to be aware of.
