As a professional player, watching how your opponents play will surely help you exploit their weaknesses. If you use a heads up display along with a datamining software you will be able to get a huge benefit over your opponents. Without spending too much time on studying your opponents in real time, you can actually move from table to table and know exactly how your opponents, with the help of a heads up display software program. This software will do it for you. So, what are your waiting for, get some online tutorials and play with HUD. Some players fold the flop 60% of the time but constantly check raise the turn. If you see that on a players stats, and they call the flop, you can often expect a checkraise on the turn. This may be a good time to check behind with a mediocre hand and save two stakes.
Without a heads up display software program you would have to watch this players close enough for hundreds of hands in order to find out that this is their standard play when they make a big hand. Other players will try to run over any table they sit down at and raise 50% of the time before the flop. You will probably pick up on this after a few orbits even if you’re playing 8 table or more, but with a HUD you’ll know what you’re dealing with before the first hand is even dealt.
