On the flop I am also 3betting for value and protection, and looking to get it in. So I would call his shove, gross as it is. If he does have an overset then it's just a cooler, if he has a straight then again it's kind of a cooler but at least you still have outs. I think he could be doing this with a monster draw too, and depending on the player it could even be 2pair. I don't like 3betting the flop to then fold to a 4bet with the odds you are then getting. Call and hope.

Well villian 3bets Vanderober and you 4bet. I would also 4bet but would make it bigger like benny said, about 11k. After that not folding. If it is set over set or he hits flush or straight just sigh.

Since the board is so wet, the only way to avoid the inevitable is calling whole way and folding diamond or 9 on turn or river. You may still lose more than half your stack doing this but would preserve your tournament life.

My apologies. 

Question 1: Never flat the raise here.  When I 3 bet on the flop I make it 10,500. Question 2: I am never folding here for 3 reasons. First is because this board is so draw heavy that he is likely to get it in on several big draws, second is because of this guys aggro image he might be getting it in lighter than you think, and third is because you have this guy covered and would still be okay (12 bb's) if you happened to lose the hand.  Question 3: Against a guy that isn't as aggro I more than likely still get it in due to the fact that the villain has around 50 bb's.  If you both had 100+ it would definitely be a different story.  If you get it in and you are beat then it's a pretty obvious cooler.  The 8 or 7 changing suit really doesn't change much imo.  Random flush draws are obviously in his range but pair/straight draw hands, straight draw hands, and 2 pair hands are much more likely.  If he does have flush and straight draw combo, you are slight dog but you have outs on the river if he binks the turn.  I would be interested in hearing your logic behind him having 88 40% of the time and the hands you listed for 60% as I find those percentages absurd.

+1 to emufart. I like the simplicity of that argument, what are you trying to achieve with the raise? It seems like you are trying to build a pot, get value off worse hands (draws, 2 pairs etc) and get the money in, so if you do this snap call and gg if he has bigger set or straight (obv prefer straight as you have a lot more outs).

Didn't mean to sound rude or anything. His range is just so wide, I really think he gets it in with a lot of hands on this flop. That's the only reason I said those percentages were absurd. It's really nearly impossible to put a % on how often you think he'll have a set or other hands here based on his range and the board texture.
