re: Poker & AJ in small blind facing a usual steal
Unless this is one of those players that is constantly and repeatedly making an obvious move to steal the blinds from a certain position, for example always making a raise every time he is in the cutoff position, I would probably be willing to let his 3x raise stand and just call and see the flop. If they are one of those players that makes obvious, blatant attempts at stealing the blinds over and over, then I would say the 3-bet is warranted. Otherwise, I wouldn't be too eager to get into a pre-flop pissing war with A-J.
A lot of players say that their pre-flop raises either to try to steal the blinds, or to try to start building a big pot when they are holding a strong hand. My raises and 3-bets are generally limit the number of players in the pot to reduce the chances of some luck box hitting bingo on me. But at that point in the tournament most of the bingo players are likely long gone. And with blinds at that level, the chances of the BB speculating with a mediocre hand are also likely to be greatly reduced. So again, I would have probably let the 3x raise stand and just flat called.
As for thinking that his 4-bet shove meant that he was probably holding better than A-J, I have had players 3 and 4-bet shove on me with a lot less. I'm not saying that folding was wrong, but in the past I have mentioned that when certain players are shown on TV having success playing a certain way, it's not unusual to see a lot of people trying to mimic their play. Having seen Qui Nguyen's domination of the final table of the WSOP
Main Event, I am not surprised to see lots of players trying to emulate his aggressive style. Just yesterday I had a player 4-bet shove on me with K-2 off. Again, I'm not saying it was a bad fold. Just something to keep in mind.
