Reckless river bluff 200 bb deep - stupid or reasonable?

Yes the only problem i think is that, you dont have much Tx in your BB vs MP preflop 3betting range. He might notice that.

That is a fair point. Still, even if he notices it, will he be able to hero-call with 99 or similar often enough for me not to attempt this sort of play? If I am in his shoes, I probably think "he has few Tx in his range, but this is probably one of those times, and if not is it really worth finding out blablabla" until I time out. I understand people do not like to fold boats, but it's quite a bit of pressure. If he starts finding the call here, then I can make a note and can start playing like this with AA/KK/QQ in this spot? I just feel it's probably a good play exploitatively. Given how deep we are, he might actually have KK-JJ in his range as well.

He might also have worse hands than AK in his range quite often, this is why I dont like the bluff as you risk ~190? to win 40, so it has to work very often, maybe just call with AK on the river as he can have bluffs? (and he only bet 1/2 pot). i think very interesting hand!

The fact that you label this "reckless" says a lot.
<checks spoiler>
I think you played that river very well. To lead would fail, but check-raising did the trick.
Nice hand

Also you're own thoughs could helps what you was thinking during the hand, but in general this seems not a great spot to bluff at on a dry board.

I would raus bigger preflop since u are OOP and deep. Like 3,5-4,5x.
I think he is hitting this Flop better.
OTT ich would c/c this hand and bluff worse.
Also I guess you Just can find out which size is best by try and Error. 4x pot is quite big. 2x pot=140bb should also so the trick.

How much would u bet with a Ten or KK?
