Nice analysis Rhound. You are right on everything except you are overlooking one fact - he will not have a set everytime. For the purposes of discussion, IF he had a set every single time, I would break even. Clearly he cannot have a set 100% of the time here. In fact, I did not think it was likely that he had a set. I've seen this minreraise play so many times lately in shorthanded games and it seems to be more about keeping your opponent in check rather than building the pot. This is due to the fact that there seem to be so many more bluff checkraises since most of the time the person who opened PF will make a continuation bet if checked to...
Regardless of all that, if he has a set everytime, it's a neutral play. I put him on AQ AA or KK fairly often here, and something nobody has even brought up yet, a bluff. This is an odd bluff but it is actually highly effective and I've seen enough people do it to have to consider it in the range of his hands. I also think that him having two big spades is EXTREMELY unlikely as I've basically never seen a draw been played this way. Usually they will call the raise, occasionally they will raise big or just go all-in.
Bottom line of all this is that the all-in is +EV. I think we agreed on that already. However, variance is a whole different issue here. I realize that variance should be kept to a minimum; however, consider this - if you are gonna tilt and have problems dealing with losing a 4k race, then isn't it just as likely that the other person is? I know this is a lot of money but step outside the box for a minute and don't think about it in terms of money. Think about it in terms of chips. When I play I don't count how much money I am up or down, because that would probably drive me nuts. Losing a $100 at a $100NL game is just as bad as losing $2000 in a $2000NL game and being prepared to lose a buy-in or two is part of playing the stakes. If I wasn't ready to drop a buy-in then I wouldn't be playing the game.
That said, it still gets to me if I lose an all-in like this, but the upside is equally great. Your opponent could easily tilt, given that he just got "outdrawn". It is also hugely benefecial for metagame purposes as opponents will give you far less credit when you make big moves on the flop. The next time I'm in a big hand like this I will have a set and I will get paid by the overpair which I may not. I consider table image to be a very integral part of my game and setting a loose/gamblor image is always my plan. What better way to do this than show that you are willing to get it all-in with 6-high?
