Losing Queen may not be the end ...

 Here is a game where I overlooked my Queen getting trapped ... ! Oh Dear ... So when this happens, you have to take what you can get ... and psychologically you are actually in a better position than your opponent because you are 'already lost', and they are 'already won' ... However, there is an old adage in chess that I learnt back in 1995 ... and that is "You have to be able to win a won game" ... !!  This is easier said than done ...

When players are not as strong, they feel that they need to protect their second-most important asset - instead of going on the attack ... with her!  Big mistake ... and it costs games as in the following example, where, instead of getting their Queen trapped they got their King trapped ... which was a far worse outcome !!
