re: Poker & $50 NLHE Full Ring: AK Preflop + Flop Lines 4ways
Already been covered basically but your options are
1) play for stacks pre
in general I'm putting a 10/8 from UTG+1, assuming he's positionally aware his range is very tight... probably something like AK and somewhere between TT+ and QQ+.
We don't fare too well against the range at all. If we raise he MIGHT fold out TT/JJ IF he's even raising those to start with which he may not be... he's not folding anything else and there's a good chance we get 4 bet.
I don't absolutely hate 3betting it though just be prepared to have to get it in if you do. I also think you will tend to win a smallish pot (aka everyone folds if he's got the bottom of his range and neither of the other two makes an idiot call) or be way behind or at best flipping with QQ for a huge pot.
flatting AK so you are oop 4 ways is just bad however you cut it. Flatting this really shouldn't be an option here.
As a related side note... I wouldn't hate a flat near as much if the AK is suited... but when you do that you are basically doing it because of the extra implied odds
a flush possibility gives you and the fact it's 4 ways with at least one calling stationy type and good odds to do so. I'm still not going to like a TPTK hand very much 4 way oop with a nit opening UTG+1.
