Hi there,
so I'm playing 2NL on 4 regular tables and have winrate 14.5 bb/100 over 35k hands and recently, while analyzing my game, I saw that my AKo (16 combos) and my JTs, T9s, 98s and 87s (16 combos all together) have pretty same winrate. Here's two graphs: first one is for AKo and second is for JTs, T9s, 98s, 87s.

It's common for my graphs to have really bad red line as I'm pretty tight and not very aggressive (VPIP/PFR/Agg/3B 19/14/1.6/6, 6-max). So I suppose that I overplay my AKo and have a lot of mistakes with this hand. Here's my stats with different types of hands. "Big ace hands" means just AQ/AK. What can you recommend for me? And which stats are good for AK? How it's better to play them on microlimits? Thanks!
