The ol' donk min-bet

[M1cKmAcK]

This is awful...
I usually see this when players think they're beat, or they don't know what to do so they bet... it might be the worst play in online poker (though I do see it live as well). It's a very obvious sign that the player does not understand the game at all.

In this situation, however, I would expect a value bet from him. The only thing that makes sense to me is that he was trying to appear weak to entice a raise... that or maybe he actually did misclick... but I'm skeptical on that.
