An Interesting but Very Tricky Puzzle!!

White to move and draw 

My friend made this interesting but very tricky puzzle.Even Stockfish need to spend some time to evaluate this position is a draw.

A very deep and have so many lines,a little careless you will lose.....But white have the same idea ----- stalemate 

Welcome everyone to think and discuss about it!!

Bf2 with idea of g4 kh5 bh4 g3

not sure how black's supposed to stop that

although black can do a perfectly timed e3 push... hmm

Bd4 exd4 g4 a4 Kh5 a3 h4 a2 g3 a1 = Q 1/2 1/2

Not so easy guys

Both of them are not correct

Your idea is right,block your king into h5 and stalemate in the end.

but the move order is important,a little careless you will lose

Bf2 e4 Kh5 e3 g3 exf2 h4 Qf4 gxf4 a4 f5 a3 f6 a2 fxg7 a1Q g8Q+ 1/2 1/2

Kg4 a4 h4 a3 Bd4 exd4 Kh5 a2 g4 then you are stalemated

sorry then g3 with whatever black plays next

wait.... if a1=Q! then Qc3 and white is not stalemated!!

Yes,you still need to check this line

Really tricky puzzle lol

impossible lol

@Eternalsky_X is it Kg4 a4 Bd4 exd4 h4 a3 Kh5 a2 g4 a1=Q g3 and you get stalmated?

Yes, this line is correct. But Black can try Qc3, still not stalemate lol

kg4 a4 h4 a3 bd4 exd4 kh5 c5 g4 a2 g3 a1=Q drow

draw

g4 immediatley?

no
