It is a pity of course. QQ played like a fish, but he was lucky. On a blackboard he had to play a check on the river, because the semi-bluff was doomed in advance, but he bets. it would rearrange his mistake on the river, because he put too many chips on this hand, and would have continued to play as a fish. You could easily make a fold on the river. Because there are closed flush draw. And there was a possible trips.
I do not see anything unbelievable, a very normal situation. I can see that he makes 2000 thousand pre-flop chips, which indicates AA, KK or QQ. In his case he has the ace blocker and k in the hand, so when Q appears on the river and he's still going strong, I think his range is well defined.
That check on river when a Qc was there made u think about his calls all along the Preflop,flop,turn and river he could havd called with A-Jcc A10cc or 9-jcc a lot of sets are also there so why you call the river if you don't make your hero calls if the hand is already ****ed.
