Leaks in my game?

Very low Fold to Cbet Flop, Fold to Cbet Turn, and high Fold to Cbet River.
You may need to fold more on the Flop and Turn to reach the river with a stronger range.
The River is the most expensive street, and its leaks cost you dearly.
This can also lower your WTSD, which seems too high at the moment.

Looks like you Raise first the same range from EP and MP. This is not correct.
Low fold to 3Bet. You can fold more vs 3bets preflop. This can have a positive impact on your results in the 3BP Caller spot.

It looks like you play aggressively when you are the aggressor and passively when you are the caller.

I think you need to trust your opponents more when they show aggression.
More folds and fewer expensive bluffcatchers. At these limits, people still like to make combinations and don't bluff enough.

Don't overplay your middle-strength hands when you face aggression and try to maximize your EV when you have strong hands.

Quick computer tip... use your print screen key on your keyboard for screenshots, and then paste. Soooo much easier than taking bulky phone photos and posting them.

I can see from one of those screenshots that you're playing on Pokerstars. Is it Zoom that you're playing?

There's quite a big jump between 2nl Zoom and 5nl Zoom. That's because the 2nl Zoom pool is the largest and it's full of recreational players. Anybody can beat 2nl by playing tight and nut peddling. What happens then though at 5nl is you have a smaller pool that has a much higher reg/rec ratio. Quite a lot of those regs then are ones that graduated from 2nl and are still trying to get by purely by nut peddling. They're playing preflop stats like 16/14 and tighter and often with relatively low 3Bet stats.

If you want to be successful in that pool you need to know how to exploit them. Put simply, you don't pay them off. Don't bluff catch against them because they simply don't bluff. If they continue after a flop c-bet be concerned as they often tend to over-fold to flop c-bets. If they raise at any point, fold unless you're nutted or have a draw to a nutted hand. This all sounds easy in practice but in game it can be quite hard. That's especially so when you are high up in your range. The thing is though it doesn't really matter. If you have a set but the river put 3 cards to a straight or 3 to a flush on the board they're never betting or raising that river with 2 pair. With 2 pair they'll look to showdown "just in case". What you have to understand is that they are gutless cowards who only bet big when they have nutted hands. Don't pay them off with bluff catchers.

All I need to see is your W$WSF, if it's sub 48% you aren't doing it right.
