In my opinion the real key to beating 2nl is keeping everything simple. You've got to remember that most people are playing 2nl with FR winnings or because theyve deposited money and lost most of it. In short, they are bad players. I play a fairly TAG 18/12 and just keep to my ABC game, raise my strong hands, see cheap flops in position with strong implied-
odds hands and muck the rest.
My tips:
Try and see a flop with nearly all PP's despite position (as long as its not too expensive). This wont work at other levels but players here just dont recognise set mining and will pay you off with pairs and draws. A huge pointer for me would be dont even bother trying to
bluff. Youll be playing against 40/5 and 70/50 and in short they wont fold to your bluffs, they're willing to go showdown with bottom pair making you AKs unpaired looking silly. Im not saying dont cbet, but chose where to cbet and when your willing to go to showdown. Finally youve got to eb able to differentiate between a bad player trying to get your chips into the pot, and you getting his chips in the pot. Sounds weird but bare with me. Lets say you raise PF with AK and the flop comes A 3 5. In the first scenario you bet every street and the donk thinks about it every time before calling you, on the river you shove the rest of your chips, he calls and flips over A9 and you take the pot, standard. In the second scenario villain calls the flop, turns a blank so you fire again but this time villian raises you. Its very tempting to get ahead of yourself and class him as a 'donk playing 2nl', assume your ahead and shove. Instead look at why he could be raising, its now more likely your TPTK is nolonger good enough and folding really could be the option. Not a great example but it the best i could come up with at 11 at night after a couple brews.
Honestly if you want some more help pm me or send me a sessions hands and ill go through them and give you feedback.
Edit: Oh and im playinf 12 tables so naturally my winnings are going to be in proportion to that, you cant expect to realistically mirror that playing 4 tables ect.
