River Queen Gets Fancy With a Backdoor 👸🏼

Masters Poker Club, NL200, 8-handed

HJ raises 3x, SB calls, I call with K♠️9♦️ and a creative approach.
Flop comes Q♣️ 7♥️6♠️. 
Hijack C-bets for 4bb and SB calls, so I decide to put my opponent to the test and make it 14bb. He calls. 
Appatently he has a queen with a good kicker and is gonna get stubborn with it. Anything better than that would raise me back. Looks like we need help.

The help arrived on the turn, which is an 8♠️ and I am now open-ended. 
I could bet but I know he is stubborn, it will take me to tripple barrel my whole stack off and it really feels like it might it might not go through. I am sure if I check he checks his top pair back for the fear of getting check-raises all-in and if I hit my straight I am likely to get paid off because my line looks just bizzare. I think if my opponent faces a third barrel on a 5 or a 10 river, he might find a fold.

I go into a “Get there or give up” mode and check; as expected, he checks back.

River is a bingo, 5♠️ and there is no way I am gonna be worried about the backdoor spades with a K♠️ in my hand. I grad a bunch of chips - I didn’t even count, but as it turned out, it was 34bb, a pot-sized bet - bump it into the middle and get snapped off. My opponent mucks his hand with an “I can’t believe this shit” face.

The reaction of the table makes my downswing day a little brighter.

CONCLUSION
Actually, don’t repeat it at home, but if you repeat, do it the same way, but bet a bit more on the river.
