Congrats, you just discovered the Traxler/Wilkes-Barre variation of the Two Knights defense. :)
Stranded White Knight!!!

Interesting game!...it also motivated me to go into Game Explorer and I was surprised at the wide range of variations played in this opening.
Only just joined chess.com after years of playing chess occasionally and fancy becoming a decent player. Fantastic site.
Anyway, alarms bell rang when white moved his knight twice during a standard few opening moves. Started studying the position (with use of game explorer) and found that this can play really easily into blacks hands and it did!!
