Any time you enter a pot, you can win it one of three ways.
- Opponent folds preflop.
- Opponent folds before river, or folds to river bet.
- It goes to river and you either bet or call, and it turns out you have the best hand.
There are standard plays, for example you want to raise preflop from UTG with AA, because you really don’t want to limp and invite several other players to get into the pot with suited connectors. You want one opponent, or two at the most.
Also one has to take into account probabilities on the fly. You have noticed a tight player who puts in large preflop raises even when the blinds are low. You are in the BB. You probably don’t want to call a raise with a dominated hand, because your KT is a huge underdog to his AK.
I would say that it is standard to never make a play without knowing probabilities and taking pot odds and relative stack sizes into account. Why would one ever call a raise unless the odds were favorable, because you have no chance of winning the pot preflop, and you already know that opponent is going to try to claim this pot if you call?
For example–now postflop-- calling a pot size bet with a simple draw to the nut flush is a losing proposition, but you might still do it if you had a small stack and needed to gamble to double up, or if you had a very large stack, and could afford to call to put opponent all-in if you hit your card on a later street.
Now add in the possibility of the draw to the nut flush plus a pair, or a gut-shot draw, or an open ended draw, or a draw to a straight flush and the probabilities of hitting an out that will win the pot are constantly changing.
Sometimes good players will make outrageous plays simply to confuse opponents. If you opponent knows that he cannot completely rule out that you raised preflop with a 3 in your hand, it creates uncertainty when a 3 comes on the flop (could you have made 2 pairs with 3x?) , but if you raise preflop EVERY time you have a 3 in your hand, then you are doomed as your hand will nearly always be dominated.
So I would say that top players must vary their strategies according to the situation and their opponents. Although you are playing both the cards and the opponents, in the end the more profitable players are surely playing on the weakness of opponents, more-so than relying on getting good cards.
I have often wondered whether there is an area in poker math that considers not just the ranking of two cards in a match-up against two other cards, but in terms of the size of the pots that they potentially could win.
For example, JT is valued as a hand, because it can make so many straights, but what about 4 5 which can make the same number of straights? Of course the odds of getting the bottom end of a straight with 4 5 plus the extreme unlikelihood of flopping top pair devalue the hand, but perhaps when you do get the top endof the straight , you will win much bigger pots than JT which is there for everyone to see.
We all know that huge pots have been won with T 2.
