JJ 3bet Pot

I think the fold is fine.
I'm surprised that it is this close.
Your chosen range doesn't included very mid-range suited connectors.
However unlikely, they're still possible. If you include some your equity drops further

Also, in Equilab there is a button "Kopieren als BB-Code"
If you click it, then you can paste the results directly into the forum post:

Board: 4♠9♣6♣ 7♦
       Equity     Win     Tie
MP2    40.85%  40.85%   0.00% { JdJh }
MP3    59.15%  59.15%   0.00% { QQ+, TT, AcKc, AcQc, KcQc, AcJc, KcJc, QcJc, AcTc, KcTc, QcTc, JcTc, Ac5c, Ac4c, Ac3c, Ac2c }

My apologies if you knew that already.

Thank you for your answer. I didn't expect it to be so close with the equity. I have often given the Villain AA, KK and QQ here.
And thanks for the advice, I didn't really know that.

Any info on the villain in this hand would be nice. JJ is a trouble hand sometimes, but is always tough to fold a over pair on the turn against a unknown.
