Players who are not that experienced often fail to read the table. Especially if they happen to wake up with a big hand.
The risk here is that you become so much in love with your AA, AK, AQ… that you can’t see any other scenarios that might be evolving around you.
But you try to be wise, play it cool, and make a min-raise to 2 blinds with your AKo.
Big blind calls (others have folded) and the flop comes 7s9h3d. Totally unconnected rainbow flop. BB checks.
You feel strong with this board and you keep pounding. You make a half pot bet.
At this point you have probably already forgot (if you ever even noticed) that you are playing against the big blind that could be holding anything.
BB calls with the 25% equity that you are giving him.
Turn brings 7c. No biggie since BB did not make a move. You follow with another half pot raise, and BB calls.
River brings an ace. You feel confident about having the better hand. You bet more than half a pot.
BB calls with 78s, and you lose.
What happened here?
1) if you have already been sitting at that table for several rounds you should have at least a basic picture in your mind about your opponents:
which of them is loose, maniac, tight, aggressive, etc. If you didn’t pay any attention to that, that was your first mistake.
2) You treated the player in the big blind like any other player. You assumed that he would continue only with the same type of hands that he might raise/call from some other position.
When a player is in the big blind he should defend pretty wide against blatant steal attempts. Your initial 1bb raise gave him a decent enough odds to call when also anties are in play. If you knew that the player in the big blind is tight - you should have raised bigger.
3) People who hold smaller pairs are often afraid of scare cards (A, K, Q) on the flop. But those are not the only scare cards. When ever the board has a pair on it you should be mindful about it.
4) What is your own table image? Are you a mystery or a straightforward player? How good your AQ/AK is in these situations depends also much on you. Are you able to bluff with a believable story or do you always get caught?
Do you recognize any of these errors in your own play?
Poker is so much more than just cards, and often things are easier said than done. We all need to take a look in the mirror from time to time.
