Mmm, how does one make a board start at the position you want?
When posting a game, right-click on a move. You should see an option to Set Focus.
so this leads us to one important rule in chess: if you find a good move try to look for a better one.
Yes, looking and recognising are two different things though 
The reason 15.Qxe8+ is slightly better is that after Kxe8 16.Nxe5 comes with tempo (Nxc7+ is threatened next).
Of course, you're still completely winning either way, so it doesn't matter in this case.
Well, I got a bit lucky that the knight covered the queen, so was winning a rook either way.
I have not really looked into "tempo" yet, however I'm guessing it means I am making the next threat in this case, on Nxf7 (rather than c7) .
I guess just interesting that not all trades with the same material outcome are the same, but I jumped in excitedly and was confused why it was a "mistake" until I looked again at the analysis.
Onwards and upwards - I hope!
Thanks y'all!
