Update:

Solid poker made another 1 grand for me. I did it on $25NL tables not $50 because $50 tables are too rocky - I can still make money on them but it's more read dependent and my preference is lower stakes + quadtabling.

Ok, I made 1 bluff against tight nit (decent player who can make laydown). I called his UTG raise in position with 56 s00ted, flop K high without any piece for me. He bets 1/3 of pot, I thought it's too meek for TPTK, so my guess is pocket pair QQ or lower. I raised it full pot, he thought a bit and called. Turn was another king, so I sticked to my original flop repping - he checks and I bet 1/2 pot on turn in order to make it look like "I want to milk you a bit with my trips". He thinks for a while and finally mucks. He said on chat he mucked QQ, but I cant be sure of it.

But main source of profit is just it - solid, straightforward poker.

Lessons learned:
- I learned a discipline to lay down overpair. Yeah, it CAN be bluff or overplayed TPTK but statistically my one pair is beat more often than not and saving a stack 3 times is worth even at the expense of folding a winner once.

Pot Control: Check/call, or check behind with made hand. Like Fnord said "time to rediscover call button"

I noticed, it's extremely hard to play big pots OOP with unimproved pocket pair. On drawless boards bet flop, check/call turn and bet the river move with overpair is quite useful - people pay me off with even a small piece of board and I am more assured of beaing beat if someone pops me on the river after I rep the backdoor flush or other weird river card. It's saves stack when facing a monster while still getting value from lesser holdings. Opinions?

I took the lion's share of my profit from poker account in order to pay for some stuff and now I'm with about $400 and I rebuild on $20NL tables while having safe financial situation (FINALLY lol)...

Operation in progress, with the intention of applying some more agression when I put someone on weaker calling hand.

Tight is right
