So I think I must have made several mistakes in this hand. I didn't know what to make of this tiny short-stacked 3bet from this opponent. So I think that put me off 4bet shoving, but the price was too good to fold pre. Now I'm thinking the flat was the worse option?
Similar story on the flop. I guess I should have just taken it at face value and shipped flop.
Turn, standard although the full allin may have been better?
Thanks for your last answer kurrkabin. I saw sense eventually.
