Bishop hata kar promotion milegi 🙂
Puzzle_V#3

Phle knight se kuch aese moves chalne pdenge taki king us square se hatkar thoda piche aaye. Uske baad bhale hi knight sacrifice krna pade but queen promotion se jeet sakte.

Nd3, Bg7 and it's a draw
.
Ne6 really a good try but black can play Bd2 and the plan is simple which is bishop wants to sit on h3 now even let's say
Ne6, Bd2.....Nf8, Kg7.....Ne6, Kh7 aise to perpectual ho jyga
.
Nh5 is wrong in the same manner explained by krishna
Nh5, Kg6.....Ke8, Bb4 and it's over now you can't promote

Draw kaise nhi hua bro Bg5 kaha hi kb mai waise bhi Bg5 invalid hai aur ek baar bishop g7 pe aaram se pahucha to rok ke baith gya na Kg6 aayega Bg7 ke baad fir Bg7-h6 repeat and repeat bingo tehde mehde

To fir bg7 ke baad to promote kar sakta hai white pawn KO apne. Kg6 to promotion ke baad black apni move chalega? Check aayega nahi black bishop ka kyuki white ka ghoda d3 par baitha hoga.

bhai geometry dekho aur jante ho hi aap ki bishop tehda chalta hai to g7 se f8 dekhega dekho ki g7 kaha hai
How can white promote his pawn?
Try to solve it on your own, good luck!
