Your stats look pretty good, but you have a few areas that need improvement:
1. Blind play. You know this already, so I'm just going to do a little math to show you how important this is. I would not really say that you have a leak in the blinds--you are doing a pretty good job of winning back a decent percentage of your forced bets. But it is still holding back your win rate.
At the moment, you are losing .34 ptbb/orbit in the blinds. Since you are playing $50, this is $0.34. Tally up your win rates in each of the non-blind positions; you are winning only $0.46 per orbit for a per orbit profit of $0.12. Because of the vagaries about how you start and quit sessions, this is working out to a win rate of .81/100 hands. (BTW; this means it is a significant leak for you to not be playing around to UTG before you quit a session, and you should not be posting to play--you should wait for the BB, which it looks like you usually do, but not always).
Now, as I said, you are not leaking out of the blinds, this is a pretty good loss rate. But suppose you could trim about .07ptbb/orbit from those losses. You would then only be losing .27ptbb/orbit, and you'd still be winning $0.46/orbit, so then you'd be netting a per orbit profit of $0.19--about a 50% improvement. This would bump your winrate from .81/100 to about 1.3/100, and it would bump your win rate to almost 2.0/100 if you also disciplined yourself to play around to your blinds as you quit sessions.
Just these two small changes to your game would more than double your win rate.
As for HOW to trim your blind losses, post 489 in this thread should help a lot. 3 betting light sometimes can also help, but you should probably hold off on that for now, but be prepared to add it to your game in the near future.
By the way: I didn't pick the .07/orbit improvement out of thin air: by coincidence, your blinds loss rate is exactly what mine was in 2007 and early 2008, and I trimmed it by .07 by implementing all of the ideas I posted in post 489.
2. Win Rates in non-blind positions. Across the board, yours are too low. When I see good preflop stats (and yours are fine) but low win rates, I conclude that most of your leaks are in your post flop decisions. The bad news is that I can't pinpoint these leaks by looking at the stats we post in this thread. You will need coaching and/or a detailed review of your DB to help you pin down those problems. I can offer a few suggestions of the most common leaks that I see:
a. Misplaying big pocket pairs. Look at your win rates with AA, KK, and QQ. Your win rate with KK should be within 1ptbb/hand of your AA win rate, and your QQ win rate should be within 1 ptbb/hand of your KK win rate (I say "should," simply because this is what I normally see in the win rates of solid players--this relationship has held steady in my DB for over 500,000 hands, for example). If you have a big gap between these win rates, it indicates that you are most likely misplaying the particular starting hand. This can be a much bigger deal than people think it is; if your win rate with AA is 4.5ptbb/hand, and you get dealt AA once in every 221 hands, then AA accounts for about 2ptbb/100 of your win rate by itself! Another way to think about it--if you are losing .27 per orbit in the blinds, you are losing 6.6ptbb every 221 hands, and AA is reducing this loss to a more manageable 2.1ptbb/221 that you need to make with all your other hands to break even (rake excluded).
So if you are losing 6.6 per 221 hands in the blinds, and you make 4.5 with AA and 3.5 with KK, you are effectively using AA and KK to make up your blind losses, and you can use all your other hands to add to the modest profit you'd be showing (about .7ptbb, I think).
So take a look at your win rates with these hands and see whether you can spot a win rate that is out of line with the others. If you do, study the individual hands and look for spots where you could have lost less or won more. Maybe you will see that you stacked off 8 times with AA, and you feel pretty good about 7 of them, or something like that.
b. Cold calling. Study this closely. Look at your win rate with all hands you cold called preflop. You should be showing a profit. Then examine the different categories of hands you are cold calling with--suited connectors (other than AKs), suited one gappers (other than AQs) and small pocket pairs. Filtered for the times you volunteered to put money in the pot, all of these categories should show a profit. If you see any negative win rates, it indicates a leak.
c. Small pocket pairs in early position. I don't care whether you are limp/calling them or raising with them. If you are playing them at all, look at your results. Many, probably most, micro-grinders whose stats I have looked at are losing money playing these hands. If you are not, fine, keep doing what you are doing; if you are losing money, there's nothing wrong with folding 22-66 in UTG and UTG+1.
3. CCPF. Speaking of cold calling, I am not a fan of your by-position CCPF numbers. They are too stable. As a rule, you should be cold-calling a significantly wider range in position than in the earlier positions, but yours barely change in the cut off and on the button. It is villain dependent, of course, but look for spots to be opening up your cold calling range in the last two positions.
4. Button post flop play. It looks like you and I share a button leak. Your W$WSF of 39.5% on the button is far, far too low (mine is 42.6%). It looks to me like you are stealing with a pretty wide range in LP, but when your steal gets called, you are reverting to essentially a fit or fold strategy and not winning enough of these hands. I'm pretty bad at this, too, but I can tell you that the winning players are all around 50% W$WSF OTB. So both you and I need to be working on following through better on our steals. Obviously, I am not the best person to coach you on plugging this leak; I would strongly recommend that you sign up for the monthly sweats and watch how your sweat partner follows through on his steals.
5. Your fold to a 3 bet % is way too high. You should not change it right now, because most of your leaks are post flop play leaks, and you should not be looking to get into bloated 3 bet pots more often when the main flaw in your game is making post flop mistakes. But you should keep this leak in the back of your head for after you have improved your button win rate and improved your post flop skills. At that time, you can start by calling some 3 bets in position and looking to flop big or take the pot away from a 3 bettor who shows weakness. You can also 4 bet more often, but that is way too detailed a discussion for me to get into here. For the time being, keep folding, focus on your post flop skills, and then start calling/4 betting some 3 bets after you have noticed a significant improvement in your win rate.
Hope this helps, good luck!
