pretty terrible advice , since the rest of the hand when the big money goes in you will be out of position guessing.
When the big money goes in, you are the one doing it against a weak fish on your left (you are reraising him, and getting all the dead money in the pot).
If someone re raises the fish before you, you know they have a big hand and you can get away from a potential loss. If you have a monster you can re raise them. Having the fish on your left, lets you see everyone's reaction to his (normally) weak raise. Personally, I would rather act last than 1st, relative to the aggressor/fish.
You now know what the rest of the field has, because they would not limp in with a very strong hand after the fish has made a pre-flop raise. They would re raise to isolate, wanting to play a strong hand as close to heads up as possible.
You should be able to outplay the fish from position or out of position. Your starting range is much better and you should be a better player. The ' big money' is only going in if you put it in, so it depends on how good your post flop play is. Simple answer is .... control the pot size.
Your concern is getting sandwiched between the fish and good player/s all afternoon (they are your danger, not the fish). Being 1st to act all day relative to the fish, is a sub-optimal strategy.
Scenario #1: The fish on your
right raises and you look down at AQ suited , you 3 bet him. Players :FOld FOld FOld FOld , Short stack ALL in ! Fish folds, Now what you do ? You are probably pot committed against a range of hands that has you dominated. If you fold you have lost your 3 bet. It's a lose|Lose scenario.
Scenario #2: You limp in with AQ suited knowing the fish on your
LEFT will raise. Players :FOld FOld FOld FOld , Short stack ALL in ! Do you want to call an all in, with AQ suited and no implied
odds ? Can you risk calling the raise and getting reraised by the fish on your left ? Far easier just to fold the blind at this stage having seen the action unfold ahead of you, and wait for a better situation.
Scenario #3: You limp in with AQ suited knowing the fish on your
LEFT will raise. Players :FOld to you .
Now you can re raise him with AQ suited, knowing it's head up and that his range should be far weaker than yours. How much money is going in postflop if you miss the flush draw, A or Q ? Probably not that much ... But you can still continue bet, or check raise him if possible on a complete bluff, if you miss.
Really, Stop playing poker at such a basic level and think about it a little ! Sometimes the (your) obvious (one liner) answer is the wrong one
