 exchange early or keep your pieces vs much higher ranked player?for me, if the situation requires I exchange (meaning my position will be worse if I don't), then of course it is necessary. but I prefer to keep those pieces and hope to turn them into increasingly valuable assets if possible. |

take 'em out If the piece does not have a target, and it is not contributing in an necessary way to your defense, then it has no value. So you exchange it for an active piece of your opponent's, a piece that does have value, because of its credible threat to your position; and after all, a threat is the seed of an attack, and if you don't attack, you don't conquer. So you block conquest, you impede attack, you remove threats, if you simply make such an exchange. A no-brainer. |

To exchange or not....depends,regardless of the strength of your opponent... If you are asking about the "even exchange" and early on I will say this: If at any point,early or mid game,if you are better developed and controlling the game(initiative)... do not attempt to exchange the pieces unless you see a clear advantage in some way,shape or form. and as its been said before: Another time not to trade pieces is when your opponent has a cramped position with little space for the pieces to maneuver. It's tough to move a lot of pieces around in a cramped position, but easier to move just a few. One sort of advantage you can often gain when you play chess is by trading pieces is a weakening of your opponent's pawn structure. If, for example, you can capture with a piece that your opponent can only recapture in a way that will give him "doubled pawns". it will often be to your advantage to make that trade. The player who is ahead in material will usually benefit from trades. So, to summarize: It's usually good to trade pieces if your opponent has the initiative, if you have a cramped position, if you can weaken your opponent's pawn structure, or if you are ahead in material. There are exceptions, of course, but following these rules should bring you considerable success. Also consider what I have mentioned before:The Bishop in many cases has a higher value than the Knight,especially as the game opens up in the King pawn games....usually a half point or more theoretically.So exchanging your Bishop against a stronger player for his Knight(especially in an open game,or even in the opening),is generally a no no.A stronger player will probably be able to utilize the maximum half point value to his advantage with deeper insight into the game than you.Don't allow him that advantage,in other words. Exchange decisions based upon a stronger player or one equal to you depends,as I said in the position and theory intertwined with "which"pieces we are discussing: Wilhelm Steinitz said that a rook is slightly better than a knight and two pawns but slightly worse than a bishop and two pawns. Cecil Purdy said that the value depends on the total number of pawns on the board.The reason is that when there are many pawns, the rooks will have limited mobility because there will not be open files. The exchange is barely worth 1½ points when there are 14 or more pawns on the board. Only when there are ten or fewer pawns may the exchange be worth 2 points. Purdy gave the value as 1½ points in the opening and increasing to 2 points in the endgame. In the middlegame the value would be closer to 1½ than to 2. Edmar Mednis gave the value as 1½ in the endgame. Max Euwe put the value at 1½ in the middlegame and said that two pawns are more than sufficient compensation for the exchange. Larry Kaufman's computer research puts the value as 1¾ pawns, but only 1¼ pawns if the player with the minor piece has the bishop pair. Hans Berliner puts the difference between a rook and knight as 1.9 pawns and the difference between a rook and a bishop as 1.77 pawns. In practice, one pawn may be sufficient compensation for the loss of the exchange, whereas two pawns almost always is. Now,as I mentioned previously,there are also "ploys"to even exchange early on against much stronger opponents in the "mirror games".Mirror games meaning a game opening like... a Petrov's defense game.On page # 96 of MCO 15 it goes on to say that the Petrov,if played with even and equal exchanges gives black few winning chances and allows white to virtually force a draw.So the advantage to early exchanging in a Petrov if you are 1800 rated and your opponent is 2500 rated?The draw is statistically in your favor,which is certainly a much better way to proceed than try for the win against someone rated 700 points above you!Sure,you do not have to play for the draw,but your chances of WINNING by NOT early exchanging in a Petrov against someone 700-1000 rating points above you is statistically very low and against you for the win.Drawing and gaining rating points for the draw is the way to go,believe me. There are other statistically higher draw openings to play the even exchange game against much higher rated opponents,but I will not get into those for the time being. |
