Exchange of Queen

@mlpareek it depends upon the situation and your opponent! If you play with a lower rated player then you will see this kind of practice because exchange of queens simplifies the situation but if you play with a higher rated player (1500 and above) you will see that they will keep the queen on the board to complicate the situation so that you fall in a trap and make a mistake !

Since most players are very weak in the endgame and at Queen-less middle games, those who aren't may seek an advantage by trading Queens early. If that's a problem for you, you need to address your own deficiencies and not complain about the site or opponents.

No, it is not.
No, it does not.
"... we can see from the above that players who are happy as White to play for a small edge in a queenless middlegame have a number of lines where they can achieve the sort of position they want. Even in other variations, the willingness to settle for a near-equal endgame, rather than trying to obtain an objective opening advantage, makes one's whole job of opening repertoire management very much easier. ... With his superb intuition and depth of positional understanding, [Petrosian] was accustomed to treating the opening relatively flippantly, and did not normally strive very hard to gain a theoretical advantage. ... it seems to me that for many players below master level, having a repertoire where there is minimal need to prepare could in fact be quite attractive. It must be remembered that, despite its shortcomings, Petrosian's approach proved good enough to wrest the world title out of the hands of Botvinnik, one of the best-prepared players ever. ..." - FM Steve Giddins (2003)
