I'm new to chess-what should be done here to win the game?

This position is a draw, the game is over. It is not possible for either side to checkmate the other from this position, not even if the side with the bare king would try to help. The same is true for ...

For white - anything but a draw?

Assuming it is even white to move there, the real question is can white avoid the loss, and I would say the answer is "no". White is down two pawns, and black has the means to create passed pawns on ...

Technique to win this same colored bishop endgame

The key here is zugzwang - White has an ideal defensive position at the moment, his king stops yours penetrating, his bishop covers the weak pawns on g4 and c4, and the pawn on a5 you can't easily get ...

Is this K+4P vs KB+P endgame drawn?

Yes this should be drawn because: White has pawns only on one side of the board, and thus cannot overload the bishop (which can sometimes be achieved if you have pawns on both flanks). Black king is ...

An important and interesting Bishop endgame

I have seen this position in Dvoretsky's endgame manual. According to his analysis, white is winning after Ke7, Kc3 Kd6, a4!, eventually getting the pawns to b5 and f5, king to d4 and breaking through ...

I'm new to chess-what should be done here to win the game?

If you look closely, the bishop only attacks on squares of a specific color (in this case, it's a light square bishop). As long as the opponent king steps on dark squares, it's impossible to 'check'...

Are there illustrative examples where a conventionally "bad bishop" leads its side to a win?

My understanding is that we call a bad bishop a "big pawn" especially in the endgame to emphasize the fact that the bishop cannot be considered a full piece in these situations. It can't move much. It ...

Is this the position from TCEC Season 18, Game 80 a win or a draw?

The key point in this endgame is that the bishops are of opposite colours. It is a trivial draw. White is a pawn up but with nothing more than barely competent play by black, white will never be able ...

Is this endgame a draw?

This is an easy draw thanks to the opposite-colored Bishops, each of which defends all of its own side's pawns and cannot attack the opponent's, so neither side can make any progress. Black's extra ...

A complex eight pieces opposite color Bishop endgame

Actually, this is fairly easy to analyze with some tablebase help. First of all, it is obvious White must make a second free pawn to "scissor" Black. There are exactly two options: 1.g3 any ...
