Tekken 5 at Uni versus a really good player. I had lost a couple of times already but I decided to try my Anna on him. Turned out that he wasn't so familiar with Anna's moveset so I had a slight advantage on his Christie. We got down to the final round and I really put the pressure on him. A lot of quick jabs and short mixups to keep him on the defensive. After a few custom strings, I got him with a uf+1,3,3+4. It knocks down and puts me right on top of him so I charged up my unblockable (d+1+2). It was the perfect tech trap. After that I kept up the poking pressure and won easily.
Beating Nitrous Oxide in the original Crash Team Racing was pretty huge for me too. I hit every turbo pad and was up half a lap when I crossed the finish line. If I had gotten a bit lucky and scored some more speed boosting items, I could've lapped him ^^
