Yep i agree with you on most points here Mack. The critical error is clearly the pre flop open from us. Perhaps i could defend the decision if we were some kind of overwhelming chip leader or had the table pegged as very weak players, but neither of these things were the case in this scenario. 

On the flop i decided to bet because i realised my hand was almost certainly behind and i wanted to continue telling the story of strength and keep the strongest part of my range (AA, KK, QQ, AK) alive. These hands would certainly want to bet for value/protection on such a wet board and i would like to bet my draws some of the time here too. I dont think my nut hands would check here very often if at all. By betting the flop i am trying to fold out some Qx and pairs below the Q. I agree that without the ace of spades i would definitely lean towards checking and folding to most bets, but having the nut spade blocker it seemed like a good spot to start applying pressure to the villain, given that i deemed it unlikely i can get to/win a showdown here. I plan to fold to raises on the flop, continue betting on spade/blank turns and re assessing on turns that pair the K or Q or other broadway cards. 

I agree that on the turn once the spade comes we need to go for it again. It was part of my plan to continue barrelling spade turns and i found it more appealing that it was the 3 of spades which paired the board. I loved this card even more because it means my strongest hands (KK, QQ) would also want to keep shovelling money into the pot and they need not worry about my opponent hitting the flush. If this was a spade but didnt pair the 3, perhaps my sets and two pairs may elect to check some portion of the time for fear villain has the flush. I can still have bluffs in my range too with hands like AJ, AT and hands like the one i have, a bare spade. I want to continue putting pressure on Qx, which should mostly fold to a bet now, and some weaker Kx hands. As you said i have a fair nut advantage here as villain likely 3 bets KK and QQ pre and raises with KQ on the flop. Also agree that JTs likely raises the flop more often than not so i’m not overly concerned about flushes at this point. Betting seems good here and i think sizing is ok although i wouldnt mind sizing up a touch more. 

Once they call this turn bet, i have to be a bit concerned. Most Qx should be in the muck by now but as you said perhaps some with a spade kicker have hung around. It feels like im against Kx here quite a bit but what Kx does he really have? KJ or maybe K with the Ten of spades very occasionally. Either way i agree with you that we have to go for it for the reasons mentioned. I can have all the nut hands, where they have few, plus i block the best flush and i seemingly have almost 0 showdown value (and if i did have any, the hands im beating would be foolish to check behind). 

All signs pointed to the river bet and thats what we did. We shove for 100% pot and villain calls very quickly and shows down Kc Js for top pair. Barring the pre flop open, i like the decisions throughout this hand. I wonder if he calls this shove with KJ without a spade? It is a pretty relevant card for them to have and i think it makes their call somewhat better?

Perhaps trying to get people to fold top pair in a $5 bounty tournament is not the best strategy when they have that extra incentive if they call and are right. Anyway, thanks for your thoughts.
