Should I get involved here?

CO is a half decent TAG 15.7/6.4/2.65 over 1,000 hands. Chances are he has me pegged the same.

Pre-flop I am unsure of. On the flop I bet call intending to donk a safe turn. I then carry through with the donk in case he is drawing. Can I fold to most TAGs when raised for a 2nd time? On the river I am in check/call mode.

My main thoughts are that pre-flop may have been 2 loose with just 1 in and that I should have found a fold at some point.

This felt very much like a 6 Max hand where a lot of loose moves are made and I played it as such.

Easy fold on the turn.
