Nope you will never be alone when it comes to picking the wrong thing to do in poker! I am really good at that... and yes, new tables get me pretty bad!
Plus, you just get that other table full of players figured out and you have them thinking they have you figured out and bam new table!
Got me on Saturday in my big $7500 tournament... I was on a roll, doing great, building my stack... table changed and I did not change fast enough with it and lost all I gained and more! Ouch!
