To improve poker game. One must know the basics of how to play poker game. Study poker strategies, different hands in poker, probabilities. Practice reading opponents. Alot of patience and clamness. It involves both skills psychological and risk management.
Easier said than done, and besides every poker player knows this and anyone who took the time to learn the game fundamentally knows for sure that this is the way to go. What OP requires is a concrete strategy that amps his win rate without using any form of cheating or whatnot. In my case back when I was heavy with Poker, is just playing aggressively. I call everyone and this especially works when you are used to playing less cards or with a smaller hand. It paints the impression that you're either calling everyone to which they could either retaliate or accept the challenge. Either way you can guarantee a larger percentage of win since not a lot of people expect aggressive plays especially since the pulse of the game right now is mostly based upon "playing the slow and steady matchup".
