Opponents is reg 21/17/8 102 hands. These kind of overbets makes me always suspicious. He could have have 6x and probably does, but never JT, T6, when i have them both in my range as played. Problem is that players in NL25 doesn't understand that i could slowplay my nuts here. I don't see the point in betting 2x pot if he has 6x, seems that he wants me to fold.

Why are you jamming if you are bluffing vs a polar range.

1 gap 4 straights are notoriously underbluffed especially after you strengthen your opponent's range OTT with an OB.

Overbets at micros are rarely spots to increase bluff rations.

Plus even if we know he has enough bluffs we don't really want to get into a psych war with a potential station who might call their entire value range

I jam because he could have some Ax diamonds or turn some pair into bluff. I have done this play w hands that have some equity in my hand on turn when my opponent has overbetted turn after cbet flop and have found success on it, because in my stakes nobody bluffs overbets and i get very tight response. But you have to only do this against players that you know also overbets lots of bluffs (eg. on A32K board w 44). But yeah might be a missed shot here, just like to experiment and put opponents to tough spots.

You have a valid point. At micros shouldn't do these kind of plays in general. My whole point here because i know many regs that overbets and puts pressure on you on boards that are favourable to them with all kind of sh*t that doesn't have any possibility for improvement. I have experimented to put some regs on test raising small their overbets and have found some success. The whole point of this play is that no one expects you to bluff overbets and you get ton of respect.

A lot going on here but I would first learn fundamentals before trying to pull off fancy plays. All fancy plays are grounded in fundamentals.

You should probably study some solver outputs and population data before saying the bolded part.
