Sitting at a live 1/3 deepish stacked game full of godawful players, except this guy... I suspect hes a 2+2er, and isn't great, but is DEF solid... Moreso by 100x than the rest of the table...

2 limpers, I limp in MP... 2 more limpers... 6ish to a flop of ... SB villan leads out $20... Folds to me, I raise to $75 ... He thinks for a decent amt of time and calls... Turn ... He checks, I bet $90, and he CRes about $100 more... He has about $150ish behind and I cover...

U??

Not sure of any reads except that I know hes at least decently tight and haven't seen him make any ridiculously big bluffs or bad calldowns...

I probably curse the gods and fold

If he had a draw he would have moved in on flop, turn CR with a draw is way too advanced for most of the players, so I think that he has you beaten with a set or a flush here.

Fold. Or, may be, curse and fold if you like it more.

solid tag limps in PF, calls flop raise then CRs +100 OOP .... he has Q .... i can't see a solid tag limping in with QQ or TT but he could have 22 as well .... IMO, this is a push or fold situation .... pot is around $448 and he has 150ish, $250 to win $600 ... tough spot ..... depending on how deep i was, i'd push.

ICE and Zmej would fold... probably why i'm not at their level yet

So he decided to make another mistake on the turn? It worked this time because youre better than the avg player. Most people would never fold there.
