Aggressively! Raise, raise, raise.
Nothing fancy. Just raise. I'm going to make it 3x + 1x for each limper in the pot in front of me. If it's raised in front of me, then I'm going to reraise to triple that raise. If someone reraises me, then I'm coming back over the top and tripling it. And so on until I'm confident that my all-in is going to be called or there is enough chips in the pot that I will be satisfied just taking the pot down at that point. If it's not reraised and ends up going to the flop, then I'm going to continue on with my nothing fancy approach. Bet, bet, bet. Raise, raise, raise. I'm not going to give my opponent any free cards to get lucky on me with. I might slow down if I'm facing a dangerous board. Otherwise, I'm happy to bet and raise until we've got e all-in.
