very good...!! this is called forced mate..

cool!

great puzzle!!

That's a good deal beyond me. It's all very clear and logical once you've seen the answer, but to be honest I didn't get close.

Phobetor, may I ask, what was your thought process to be able to find the Bg7 move?  You could have given me a week and I wouldn't have found it.  Great puzzle.

It is an interesting puzzle

That's excellent Phobetor.  Great insight.  Very helpful indeed.  Many thanks.  I better get back to tactics trainer and keep working at it. 

nice..
