All in flop with AhKs in flush nuts flop

I do not like it. You should cbet smaller and call if it was a min raise again.
Villain is raising vs a pot bet on this Board, what do you expect him to have?

Look how tight this guy is, be happy he mini raised you, not 3xed. Cbet smaller (how many worse hands do you see calling there and better folding to the mono board)?

I expected JJ+,AK,AQ from his 3-bet call and I had Ah so:
I thought I had a strong-ish draw.
I thought cbet pot would gave me more fold equity as well as inflating the pot in case the flush came.
Was I wrong? Why?

With you having the Ah you lower the possibility of him wanting to call your bet on flop.
You will face sets, maybe some straights and already made flushes.
Your draw has 6-8 outs and it is very obvious.

WHen you cbet THIS big (pot) on a T98 monochrome board, you will only get action from top of ranges you know you isolate yourself vs strong ranges because people will tend to drop their weaker parts faced with such a bet. Cbet is ok but the stack off is a spew imo.

Why the pot bet???? did u wanted to play it fast?? Your range can be capped with your bet sizing OTF. As played, once he raises you, you are hardly ahead and you don't have any fold equity imo and is a tiny call only for odds.

Just play a straight forward poker in microlimits and don't try to oveplay your hands.

I didn't read the posts above but I guess everything is already pretty much said
Betting this big on this board on 3bet pot is not good. If you bet, it should be small, like 1/4-1/3pot.
Now you are going broke vs a tight guy only with a flush draw. I don't like it much.
