If someone asked me what stuff actually helps when you're just starting out, I'd say most of the fancy chat can wait. The advice that held up for me was the boring gear: play fewer hands, stop limping rubbish, and pay attention to where you're sitting. Sounds basic because it is, but heaps of new players try to get clever too early and just donate chips.
The biggest one for me was learning that position matters way more than most beginners think. Being last to act makes life so much easier, no mucking around guessing what everyone else is doing. Early position with junk hands? Just fold and move on, no worries. I reckon half the pain at low stakes comes from people convincing themselves that suited rubbish is somehow playable from anywhere.
Another bit that actually works is keeping your bets pretty straightforward. When you've got a real hand, bet it. Don't get too cute with slow plays every second orbit, especially against players who'll happily check behind and kill your action. And the bluffing... yeah, beginners usually do too much of it. One c-bet now and then is fine, but trying to blast people off every pot is a quick way to torch a stack by the arvo.
The only beginner tip I never really rate is when people dump a massive pile of theory on someone straight away. Pot odds, range merging, solver lines, all that stuff has its place, sure, but if a new player can't fold K-9 offsuit under the gun yet, it's probably not where they need to start. Better to get the fundamentals clean first, then layer the fancy stuff on later.
Curious what other regulars reckon helped most when you were starting. Was it hand selection, bankroll discipline, table position, or something else that finally made it click?
