This one I feel is mega standard for extracting value, but I'm wondering about my 4 bet preflop. This guy is the same one as my other post so with the 80% VPIP I'm not too worried about scaring him off, but should I be? I don't really have any info on him reacting to raises/reraises preflop so I'm not sure if I should be reraising his 3 bet. Also, should I ever really be worried about AJ here? I find that I tend to analyze after the fact, but I don't really do it much in game. I'm just curious if this is optimal at this level to just bet, bet, bet. I got value this time, but is this usual/should I keep doing it this way?
