To start with the HUD. Step 1 sample size is everything (how many hands has been dealt while you have been at the table) . To start that would need to be tour first stat to pay attn too.
Second set of stats is VPIP (Voluntarily put money in the pot) and PFR (Pre Flop Raise) . You can pay attention to this stat when you have 500 to 1000 hands tracked on an opponent. The number will look similar to this
23/19 or could be 54/5. Take the two numbers and pay attn to the gap between the first VPIP and PFR. The wider the gap, the more passive they are.
The 54/5 is the dream opponent. Typically the opponent is limping to see a flop cheaply. If the flop hits he will call you down to the river. If he raise FOLD!!!!
The other opponent, the 23/19 he is a sticky opponent. Little tricky. His VPIP and PFR is narrow meaning he is going to play straightforward with some stickiness to him. This is an opponent that will play more straightforward with a pretty good range to play in position. He will play pots to win and you need to pay close attn. He may be
bluffing or he may be value betting. He is sticky so it's a gamble to play. This is the stat that are difficult to play against. The higher the VPIP the more wider his range is. The higher the PFR, the more aggressive he is with raises and 3bets and 4bets he will be. Hope that helps. [emoji4]
