I think you can call with any 2 cards if you think your opponent is weak or you can see a cheap flop. In this case a PS micro tournement at the early levels plenty of fish to take out and doubling the bb is not realy a raise I gambled. I hit the flop.
Suspected an ace rag and when I went all in on the turn expected the call as odds of another ace coming small.
But as happened it wasn't my day. Put your note book away I won't be doing this on forum games
