Calling a large flop bet with just two overcards and no draws is a significant error that burns chips against a range advantage.
Calling here is a major mistake. We have no pair, no flush draw, and no straight draw against a large sizing that represents a strong King-high range.
Note: Floating with Queen-high and zero draw equity against a 1.3x pot bet is a massive leak; we are crushed by Villain's value and even their bluffs.
Checking back is correct. The 2h is a blank for us, and while it completes a straight for 43s, we still have no showdown value to bet.
Folding is the only option. We have reached the river with only the board pair of twos, and Villain's 66% pot bet is never folding to a bluff from this part of our range.
