Since you are useless scum, I am just going to block you now.
Who is the most powerful ??? Bishop or knight???

@kindaspongey Preference and the original question, which is more powerful, are two different questions that many here do not understand. It has been firmly established in the 100 years since that the B is more powerful, more often.
Most people would probably prefer the more powerful piece so for most applications, which is more powerful and which do people prefer is really the same. I think most people agree the value of a bishop is slightly more than that of a knight, but neither have any "power" until someone uses the piece in a game of chess. In cases where the player is better with one over the other, that piece preference is the more powerful piece. It's not just about position, because it's the ability of the player that determines the position. Even though bishops are traditionally considered to have more value, I do understand why, all other things being equal, some people are just better with knights. For those people knights have more "power".
“The weaker the player the more terrible the Knight is to him, but as a player increases in strength the value of the Bishop becomes more evident to him, and of course there is, or should be, a corresponding decrease in his estimation of the value of the Knight as compared to the bishop.” - Capablanca
To refer to the oft mooted question, "Which piece is stronger, the Bishop or the Knight?" it is clear that the value of the Bishop undergoes greater changes than that of the Knight. ~ Emanuel Lasker
Now whether or not he is implying that is a positive or negative i do not know?
Could somebody please elaborate?
There is a famous game played at St. Petersburg in 1914 where Lasker defeated Capablanca using the Ruy Lopez (aka Spanish) Exchange Variation where White exchanges Bishop for Knight on move 4. Lasker also exchanged Queens on move 6. I expect the game is easy to find on line if anyone is bothered.
Generally Bishops are stronger than Knights because they can move from one side on the board to the other, but the advantage is very marginal. Also, the Queen can often combine with a Knight more effectively than with a Bishop.
@StickyFingersRequiem, hmm LOL, you have a record of 117 wins and no losses and no draws? Geeze, I wonder how you managed that? Did they already catch you?
