This is spew against an unknown but is a play a make a lot (although generally with air, not with a nice amount of showdown value) with a read. I think evaluating bluffs in a vacuum is rarely constructive. Can you tell us anything about this guy?

I'm also not sure why your bluffing 2 streets here. When the A of diamond peels off we can heavily weight his range towards 1 pair hands which may contain a diamond (ie 77). Our hand has a lot of showdown value. I would check the turn. Then evaluate on the river if I wanted to turn our hand into a bluff. If you had air I would like this a lot better than when you have 10/10. And checking the turn and bluff raising the river is much scarier and likely cheaper than firing the turn and the river.

But really as I said you need a read here. A good player is not going to believe you peeled the flop with the K of diamonds which is all your repping. If the K of diamonds rolled off instead of the A this is a much better play.

oh and your bet sizing it pretty good i think. I might do 60 on the river.
