I found them extremely random as they are able to play almost any 2 cards if they find it interesting. Why not to call tight pfr with J5o, if the Jakson Five is your favorite band. 
I considered moving up the limit by depositing some funds, however I am not confident at the moment. If you would suggest 5 days ago I would go for it but the losses of last days are not OK. I hope I will not go busto with my BR but still going down after yesterday session.
Anyway I think I found the leak in my game. I play agressivelly multiway pots what is obviously -ev and costed me a lot of money.
Still I have a question how do you guys play when you probably do have a second pair. So let say you have JJ, QQ, KK, and flop comes Axx. By digging in the database I see that oponents is likely call with Ax preflop. Therefore it is probably better to cbet(depending on oponent) and fold to any resistance.
Another question is how do you play preflop with many limpers? With two and more limpers if we decide to cbet we have to go AI. Floping pair happens 26% time.
Analising this scenario:
raising 6bb.
3 times you raise 6bb(asume 2 limpers and one caller) and we do not hit the flop. Pot= 14,5bb. We fold every time. Costs 18bb.
1 time we hit and make 22,5bb.
Therefore 22,5-18= 4,5bb profit
going all in.
Doing this with suited A10+, TT-88, KQs gives us 48% equity agains 10% range.
Let say that the limping range is 25%, and one will call us with 10% range.
Therefore 15 times we take 3,5bb. That is 52,5bb.
If he calls 6 times we loose and 4 time we win. 120-80=40.
Profit 12,5 what is more than in the first scenario.
Anway how do you approcha these problems as you do not have nearly enhough time to compute it on the tables.
