Point of Puzzles?


Yes.

Yes. You have to work it out. Look for a move and then look for a better one. In a real chess game there is no one whispering a solution in your ear so puzzles are the same. They develop the skills of exploring different moves (candidate moves), calculation, and visualisation. In the puzzle look for forcing moves: checks, captures, and threats until your pattern recognition picks out a tactic. When you find something, verify it by calculation and check carefully for any moves that refute it, the puzzles defensive resource. Do this all in your head and, with regular practice, your chess will benefit.

You’re looking for a way to ‘resolve’ the current position into something more favourable. That could be checkmate, material gain, promoting a pawn, or in some cases (more rarely) you might have to find the only non-losing move. A lot of higher rated puzzles have a false lead - a move that appears to work but doesn’t, so it’s important to consider the opponents possible defences as well.

In short, the point is to find the best move. It can be a checkmating sequence, it can be gain of material. In some rare cases, I believe it you'll need to force a draw when you are many pieces down (perpetual check for instance).
i have a question. how can myy opponent get 3 queens?
by the way i just started playing chess
By promoting pawns to queens. You aren't limited to only 1 copy on the board at a time, even though you only start with 1.
