There are no tough regs at 1/2 live. The best players at 1/2 are only mediocre and still have plenty of flaws in their game that you can exploit. Without knowing the specific players, I can only give general advice:
1) Tighten up in early position. Anything below AQ is a fold UTG when you're on a full-ring table. Most of the regs open too loosely from early position.
2) Loosen up in late position. Any suited Ace, suited connector, suited King with a decent kicker, or any 2 broadways are fine to open in the CO/BTN. Take advantage of being in position.
3) Avoid flat-calling raises. There are times when you can flat-call (if you are set-mining or have a suited connector), but generally speaking, you should aim to 3bet or fold when facing a raise. You want to be the aggressor in as many hands as possible.
4)
bluff squeeze when you get the opportunity and when you feel that there is some fold
equity. For example, if you have K6s on the BTN, there's been a raise to $10 and 2 callers, consider 3betting to $55 as a bluff (this works much better when you're not playing against fishy calling stations).
5) Keep an eye out for "lookup artists" - people that float flop Cbets liberally just to see how you react on the turn. When facing a lookup artist, try to reduce the discrepancy between your flop Cbetting frequency and your turn Cbetting frequency. That is, try to barrel more often to punish them for floating you on the flop, as well as check-raising some turn cards with strong hands and avoiding Cbetting wet flops (like a Q98 2-tone flop is bad to Cbet).
6) Look for spots to semi-bluff and barrel turns with equity (gutshots, open-enders and flush draws are great for semi-
bluffing). Also consider whether it would be more profitable to raise the flop with a flush draw or open-ended straight draw, or whether it's best to play passive against that particular opponent.
7) Bluff some rivers with busted draws if you feel like you can get away with them. Otherwise, just give up and check/fold when you miss. Also, keep an eye out for busted draws when contemplating a hero call on the river.
Good luck!
