Just been moved to this table, so no info on opponents. First hand I 3 bet from the button over GordonFlesch's min-raise and get a fold. This is the 2nd hand. How is my bet-sizing with this stack? Does anyone flat here instead of 3-bet? What's the play after sb shoves? Any thoughts would be appreciated .
