Welcome OP. This is in the wrong forum, I'm afraid. This is a live cash game forum. This needs to go into one of the tournament forums, but without knowing the buy-in I'm not sure which one.

I'm no tourney reg, but I think your PF raise needs to be bigger over limpers and out of position. After that flop, it doesn't matter how, all the money is going in.

In any case, please post in the appropriate tournament forum
