knight vs bishop

A bishop is, under normal circumstances, worth 3 points. A knight is worth 2.9.
You can't checkmate with 2 knights vs a King unless the weak side makes a mistake (you can easily checkmate with the 2 bishops or with a B+N).
Of course, there will be positions where a knight is worth a lot more than a bishop, just like there are moments in life where a little bit of water could be worth a million bucks (for example if you're about to die of thirst in the desert!)
Having said that, when you're starting out at chess, knights are trickier.
hey guys, what do you think who is more powerful between knight and bishop?
