40bb cash game strategy:
- Play very tight preflop. Only play premium hands like AJ, AQ, AK, KQ and 77+. Fold everything else, including hands like AT, KJ, QJ, 22-66, T9s, etc.
- Make a big raise preflop: open to 5x + (x per limper). So if you're UTG you should open to $10 at a $1/$2 table and if you're on the BTN and there's 3 limpers before you, then you should open to $16
- Plan to get your stack in every time you hit. For example, if you have AK, you raised to $12 preflop and got 2 callers, you've got $68 behind and the board comes KQQ, then you should bet like $20 on the flop and bet the other $48 on the turn. If someone happens to have Qx and hits trips, or JT and hits their straight, then bad luck, but you should be happy getting it in on this flop.
- Plan to 3bet shove in squeeze spots (when there's a raiser + callers) a little looser than usual. So for example, you have 99, someone opens to $10 and gets 2 callers, you should shove all-in for $80. The fold equity alone makes this profitable.
Good luck with playing a mid-stack strategy! This can be fairly profitable if you play it well.
