@ H.G.:
Regarding the K+Q vs. K+B+N fortress position, are you sure an Amazon can be substituted for a Q and the result still should be a draw? In the following position (White should be able to obtain it, I'd guess), Black to move loses. If White only had a queen Black could retreat his bishop into the corner in the diagram, but with an Amazon, White mates with 2.Amazon-h6#:
