This is a chess problem taken from ICC (Internet Chess Club).
White to mate in two moves:

नक्शाज्यु, अरुपनी जावोस् न

and as for black moving first and winning, i dont see any clear-cut way in a short span, because the white king has many degrees of freedom. however, the first step would be to take out the white rook in the first move. Even then, white can still checkmate if black makes one small error, but chances are black will go on to win

Move the knight so the king has only one place to go.
1. White Horse F4 - King h7
2. Rook H1 ++

This thread reminded my old days in ASCOL and Pulchowk where i used to take part in chess competition. Probably now i have forgotten how many characters are there in a chess game.

Ok friends, here is another problem taken from Chess Problems Unlimited. White to mate in 3 moves:

` 1.White K e7
   black ...
   2. Q f7
     black ...
     3. K (x) g6

1.White K e7
black ...
2. Q f7
black ...
3. K (x) g6

but 2. .... B e4 will prevent the mate

My solution:
1. N e7. .....
2. N f5 ....
3. Q x g7 ++

sorry... 1. ... B e4 will prevent ++ in 3 moves.

What more, good solution! Here is another problem:
White to mate in 6 moves.
4)

Sorry, if 1)white N e7 black B e4,
then white 2) white Qxe4 black g5
3) white Q d4/d5 ++

.world_map... how can this be a solution:
1.Ne7 ...
2. Qf7 ...
3. N(x)g6

if
2. Qf7 Be4.
3. N (x) g6+ Bxg6.

That was for the previous one:

.world_map, again.. what is
1. Ne7 Bb7 and not Be4

sujan jyu, i see a problem in yours too, the same bishop move you talked about will prevent your mate too... the (moved )bishop at b4 can take the knight you moved into f5 (your second step). this prevents checkmate in 3

the option if black moves bishop to b4 is
2) white q x b4, whick leaves black with only one option
pawn g7-g6, then
3) white qe4-e5 checkmate
