I'm not sure, but I remember a hand where I had a straight flush going down, while my opponent had the straight flush going up, since there was an 8, 9, 10 of clubs on the board. We both had more than 250BB in NL5, that one hurt.
If I have AK, it rarely improves.
If I have a big pair (KK, or lower), it will be run down with AK.
But if I have pocket tens, they usually win for me against anything (including AA, AK etc. )
I'm losing the most from the blinds... doesn't really matter what the holdings. I'm working on it though - - making improvements on my BvB play and fighting back with 3Bets out of the SB.
Ace 10 suited for me is by far my worst playing hand, I have some weird obsession with it always have not sure why my Achilles heel I guess! AA has been running super poorly for me lately also
Jacks has a reputation as a losing hand, however I think the hand that loses the most in the long term is 5-2, but if played with the right strategy, that is, in a multi-way pot where it is cheap to complete the bet, it can yield a good value and it will be difficult for opponents to read correctly...
