i didn't understood, why would white accept draw ?

Nice one!

Actually is going to be a win for White. Why is it called as "White to Draw". In few more moves it will be a White win.

I found that one really easy to find given the title, but playing it in a game is a different matter.

Indeed.

1. Qh8+ Kxh8 2. Rxf8+ Kg7 3. Rf7+ Kh6 4. Rh4+ Kg5 5. f4#

Nice drawing technique.
