From your post this reader has a question; are you looking for options or just trying to make money from fancy moves?
A player who is looking for results from certain position plays; this is hard to accomplish without experience and understanding of the players who act in front of them the majority of the time. Especially the two to the right of you; do they limp in worse
hands than you? Do they slow play their hands pre-flop? Will they check-raise semi-
bluff with worse hands or do they play straight forward on the flop, turn etc… ? This information takes time to gather. Once a player has this information and can understand how people play in certain situations without as much information and correctly identify the situation then creativity and fancy play can be profitable, but with the best information there is still no guarantee but you will be better prepared for surprises and can adjust your thinking according to the present situation. Until you have been in these exact situations over a period of time and the information about creativity is in your unconscious mind or “in your back pocket” can you see a difference in how profitable any fancy play is better than another.
The scenario of the J9s hand I would have the ability to play both sides of this with hands similar in this position to mix up play the advantage of putting in the raise of limpers pre flop has advantages but also playing in multi way pot is what J9s needs to help build a pot that most weaker players will over value one or two pair when you hit the flush. You do not play for the jack on the flop but have position and the proper understanding of each player; then experience of knowing are you ahead with the jack but this is player specific in these situations.
My rule of thumb is straights and flushes with hands that have kicker problems. Most in late position will limp in hands that have your kicker dominated and until you have this information play for straights and flushes if you miss fold cheaply. Semi-bluff on the flop when you hit the draw but only against people who are still drawing or have a weak made hand and again player specific; other situations pre-flop raise and narrow the field that will knock out the blinds if they have a tendency to fold and create a “dead money situation” that will help to keep you position absolute instead of relative if the blinds have a tendency to check-raise or put pressure on what looks like a position move. This is just some of the things this player has built up playing these and similar situations. Hope your day is going well and glad to have met you.
