Welcome to the forum!

1) Play your game, not the donks'. Depending on how often he does it, I'm calling him with QQ+, for sure.

2) Ever heard of a trap? It's classic from the supernit. Unless I catch a good peice of the flop, I'll fold to the min-bet just to piss them off.

3) Good for stealing, not much else. I will almost always open raise Axs from BTN, CO, an CO+1. Fold otherwise.

4) IMO, I need a really good feel of the table before I play SCs. They work much better on a tigher table, and therefore should be played sparingly at the lower limits. Good for stealing, if possible (BTW, don't try to steal with SCs when one of the blinds V$PIP is >35%). You need to look to hit the flop hard with 2-pair or pick up the open-ender/flush draw. That's it. If you can buy the pot on an uncordinated flop, cool. Otherwise, let them go. Obviously, they should be played LP.
