ways of mating.

In my last game my penultimate move created 4 different moves for mate. Actually, they could all have been avoided but that is not the point as it got me thinking.

What is the greatest number of different mating moves possible in a position with none the previous move? Is this swiss gambit territory?

According to Jeremy Morse, "Chess Problems: Tasks and Records" (1995), the record for white mates is the following:

1 h8(Q)! (threat 2 eR~), and black's various defences lead to 24 different white mates.

I'm not sure if this is what OP wants. Sure, in some lines you will get almost 14 possible mates from the Q/R battery, but it's only 14 because it has to be from the same position.

It should be possible to get more.

Swiss gambit is right but I did enjoy the above composition.
