You should be careful with the Stafford gambit
If you now take, 4.Nxc6, you are in a world of hurt if black knows what he's doing.
(Taking on Nxc6 is something like +2 for white... but only if you are like a 2500+ player, or an engine. If you are a mere mortal, you are in a world of trouble, if black knows his game.)
Might be easier to just retreat with 4.Nf3
Just curious, as I recently had the Scotch gambit played against me while I was black, and I severely misplayed the opening. I would love some ideas on a bunch of common gambits or perhaps even uncommon ones that may be counter-intuitive. Opening traps against me while playing as white would be lovely to know as well. I'm roughly a 900-1000 rapid player and am looking to work on my openings.
