2nl is a bit of a weird limit. It's real money but to a lot of people the sums are so small that the pain of losing a couple of cents is outweighed by their natural curiosity concerning the great questions of poker. Those would be: "Will my hand get there by the river?" and "What does that bastard have?"
So yeah, in general, people fold here way less than they do at higher levels. On the flip side they tend to be far less aggressive. The net result means that you actually have to make adjustments that would be sub-optimal at higher levels but I think work really well at this limit. Here are a few examples:
(Health warning-don't do this at higher limits or you'll get murdered by observant and aggressive players)
Small & Medium pocket pairs
From early and mid-position I would advocate limp-calling these and playing them purely for set potential. Post-flop if I don't hit a set I fold them. Playing them this way ensures that you pay the minimum price to speculate and lose the least amount when it doesn't happen. When they do hit though I'm betting as much as I can get away with as often as I can.
The reason why I think this is they best way to play these hands is that say we opened 77 from MP. We'll probably get 2 callers. If we don't hit our set there's a very good chance that a c-bet won't take it down against the loose-passive types that are rife at this limit. So now you've invested 6 or 7 BB's in the hand and we've got a very marginal hand. The fold equity just isn't there to make this a profitable play.
Suited Aces and Suited Connectors
I'd play these the same way except not from early position since these rarely flop made hands so it's nice to have some position post-flop. I'm more than happy to limp after other limpers with them though. Once again unless I flop some decent equity I fold them.
Opening more Lower Broadway
At higher limits hands like K10, QJ and A10 can cause you a world of pain after you end up going to showdown and getting out-kickered. At 2nl though their status gets elevated due to some opponents who will call multiple streets with top pair-awful kicker. Obviously this one is particularly opponent-specific so keep an eye on their stats to see how wide their ranges are.
3bet bluffing and blind-stealing
I would do way less of both of these due to lack of fold equity. Obviously if you're up against a nit this changes but against calling stations and aggro-donks you're burning money.
Premium Hands
Play them face-up. Big bets pre and post-flop
If you play in the above manner you should notice a few things.
- Your red line will be a negative slope since you're not bluffing as much and you're folding a lot more after missing flops with your speculative hands
- Your blue line will look like a stair-case which should hopefully be going upwards bringign your green line with it
- Since you're entirely dependent on making hands to win it is possible to go for stretches when you're card dead where you're not winning but in the long-run this won't last and if you're disciplined you can easily ride it out.
