Re: the mini-raise
 

I find more often than not a minbet means they're on some sort of draw. If the board is ragged, then this isn't the case. If there's two to a flush or connected cards on the board, I go ahead and bet the pot if I have a hand or was preflop raiser. The majority of the time they end up folding.

That said, there are very few players who minbet to keep everyone in when there's a lot of players. This juices up the pot for them. Keep note of these players.
