A puzzle from one of my own games

It look like Black is lost, but he has one last card to play. 

Here is puzzle from one my owen games. 

another good one.. but freddy don't post solutions along with puzzle.. so we dont work and solve.. simply click on solutions.. may be post a puzzle then after 1 day post solution.. that way we will get feedbacks

do not know how to post the solution.

i mean first when posting puzzle show only the diagram (not the moves..) later post the puzzle as such with answer!

give it a try .. dont worry..

ooh ok I did not realise that you could do that.

this is how we learn... i did the same way
