Hello everyone,

 I have always preferred knights due to its fork power, then I have read in many places bishop is stronger, and I never understood this.  Then I found a great way to understand this. Can anyone show me how to draw as black in this puzzle, not just the moves a computer can do that, a general strategy I can use to draw in these games? Thank you so much. Black to play and draw.

I can't say for sure that this is correct but I think the general idea is to come from behind and attack the pawns then try to achieve a position like

and in this case all you have to do is just basically move the bishop around and if the white king moves then you can just capture the c-pawn

the bishop should try to make the pawns form a chain and control all the squares in front of the pawns. However, this is winning for white.

@Yeetsleep: Thanks a lot for the response but it is still practically hard for me to do.

@Snudoo: Thanks a lot for the reply, however how do you form this pawn chain, it is not easy to do so. Also this position is a draw not a win for white, I tested with stockfish multiple times. Thanks

@Yeetsleep - White is going to avoid the pawn chain.  Passed pawns are strongest when they advance in lockstep.  White would not advance the pawn to e6 unless the c-pawn were on the 5th rank first.  White also needs to avoid leaving the center pawn backwards on a light square.

As long as two of the three white pawns are side-by-side, they keep the black king two spaces away.  There may be a draw here, but I think black would have a very hard time holding it if white is patient with his advance.

Checked the tablebase - it is a draw, but there are several lines where black's only drawing move is not terribly obvious.

Easy draw for black. Doesn't matter how patiently white advances if he keeps the king in front of the pawns and the bishop on the diagonal where the passed pawn closest to the white king is advancing it's a draw.

It's not quite as procedural as that.  If the pawns all get to the 4th rank with the white king still in front of them, white wins because the subject diagonal is too short.  Black can force the white king around behind prior to advancing all the pawns that far (black needs to force specific pawn advances in order to do so), but this is tricky because of the 2-space option, which all of the pawns have initially.

White also has the option of leaving a pawn on c2 or e2, pushing just the two pawns forward until white needs to give tempo.  The pawn in back can't be attacked by the bishop or the king, as both are needed to blockade the two pawns which are further forward.

Yes, a skilled player who knows the endgame should hold it, but someone who hasn't learned it isn't likely to figure it out over-the-board.  I don't know that this fits the definition of "easy".

If white leaves a pawn on c2 or e2 there can be no progress. And you don't need both pieces to blockade two pawns. I have no idea what you're talking about.

lol i actually thought of that

Hey thanks a lot for all the replies.

@IM pfren: Thanks a lot for showing a method, while showing alternatives as well. It is really good but I think I will have to go through it and play those moves few times to understand, as this is a quite difficult end game for average rated players like me.
