what are the sharpest 5 opening variation among all of them?

I play the King's Gambit - sharp as broken glass & cuts like it too - and run near a 50% win rate in Blitz, but that's just me. No-one else knows it at all - and I mean (almost) NO-ONE. Out of over 10,000 games I've played here so far, only *one* other person ever played it.

 You might like the Latvian Gambit with black if you like the KG with white. Risky to play with black, but due to it's rarity it can be a surprise to the opponent. 

Easy!
