Cant think why your opponent doesnt just give up!
Win Streaks?

Not necessarily...demotivation can have a real negative impact...i suspect the opponent maybe more interested in the bikini rather than the game! :0)

A win streak against only one opponent? Or in general?
Against one opponent....mmm maybe it is like 5 wins in a row.
In general, well now I am in a 10 win streak in 2+1 bullet system. My overall record is like 16 or 17 wins in a row I think.

I don't really care about streaks. I have found out that I have lost more games that I won. I think when people do streaks they vs lower rated opponent my rating is nearly 1400 and my average opponent is about 1360. I am personally at chess.com to get better not to boost my ego by beating other lower rated players. After this u will find that your rating goes up. Thus think u are what your rating says but u aren't u are simply versing players that are worse than you. Chess players have both streaks and slumps so its not the biggest thing that will happen to you if u have a little streak over somebody who is worse than you
Wondering what the longest streaks are...I entered this game to have chat stopped - wondered why til I saw:
