Mate in two (standardized)

White to play and mate in two moves. This problem is compliant with SirDavid's and NM tonydal's suggestions regarding removal of extra pieces. However, I have a feeling I made it too trivial...

The solution is in  white .if you want to read it you can select it.
solution:.Nb6 ...axb6   .Ra8#


Good puzzle. Not to obvious for me.

Correct, Gert-Jan!

This one took me longer than the other one. Don't be discouraged if they seem trivial, again, somebody who uses logic rather than sheer calculation can solve most #2s with few pieces easily. After all, the check on the White King removes most possibilities. You're doing much better than I do with these.

I believe this construction is more efficient if there's only one solution; however, I don't have time to engine-check it.

Shouldn't the bishop be on f2, though? In the diagram Nb6, Kxb6, or am I missing something. (wouldn't be the 1st time)

OK, I see. Just woke up, haven't had my coffee. That's my story, and I'm sticking to it.

Nice, the idea is preserved.

Thanks :)

By the way, if the Bishop was on f2, Bb6 would be a second solution. I figured I'd add a second defense if I could, since there was only one legal move for Black in the original.
