A river shove bluff

I want to share a hand I played just now on NoiQ (50EUR table). I had just been stacked with a straight vs quads, so wasn't too happy.



This was a very tight player - 5/5 over 50 hands, but weak postflop. No showdowns in 50 hands, and I had already taken a couple of pots from her by calling Cbets and bluffing the turn.

Here my PF call is standard on the button. The flop is a bit scary for a PF raiser. Her range is maybe just overpairs and AK. The Cbet is half pot. I would peel this bet 100% of the time with overcards. Turn Cbet is also half pot. I can probably raise this and win a reasonable percentage of the time, but the bettor can probably put me on a draw and call. Instead, I decided to call the turn bet and bluff any ace or six on the river. Six comes, villain checks to me, I take it down.

In hindsight, my choice of bluffing outs was poor. I think after the weak Cbets, AK is a very significant part of the villain's range. So bluffing on an ace is a no-no. Instead, I think bluffing any six, eight or club is probably better - or even any non-ace. I am also expecting any king or ten to give me a winning hand pretty often. The six of clubs which arrived was really the perfect bluffing card.

Any thoughts?
