vs mp gotta call that shove. Turn card is just great for you (reduce both 43 and 44 - both debatable calls preflop), villain represents pre slowplays and in generally should be checking turn quite frequently as well as raising flop not often.

Would imagine QQ plays that way, more creative players will have JJ here but very little amount of bluffs because IP doesn't have incentive to bluff(not floating flop) and turning some AQs into a bluff there.
Vs tight players I will consider QQ+ as a call, and don't think I will bet turn all that often.

he had QQ :)

Double checkraise is very weird, but probably value-heavy. He could have TT-88, as well slowplayed QQ-AA. Maybe some top pair hand as well, thought not likely. He could also have A4s, though that's a loose call preflop.

For bluffs, he could have pair+FD type hands.

It's a close call in any case. In general, when I have no idea what a line represents, I err on the side of folding.

Jeff_, do you mean what I am doing in this sitaution with QQ against 3bet MPvsCO? I mix 4b/c and c, I preffer 4b/c

People more often call TT, JJ in this situations there. I think AK is probably 50:50 between call and 4bet. Anyway thanks :)

200 bb deep im checking that flop

Checking turn after getting raised on flop as well.

As played gross spot but I think it's an exploit fold vs general population at 50nl
