Welcome back,

Take a look at the post that I made on microlimit hands. You may be on to something with the observation about a table tightening up? I playe on Fortunepoker right now, its a European site and the players are crazy as they come. At the lower limits, you'll find many tables where five to seven players see the flop!! Its great when you have a hand, bad when you get sucked out on when your KK get snapped by Q3 or 9 5s. I think what happends is, quite often a few players will notice that you are playing tight and only with good cards. They themselves will begin to mirror you. They may be noobs, but they are not all stupid.

Continue to use your strategy. As AOK told me, dont worry about the bad beats. When your multitabling, you are too busy to even worry about your last move.
