How often is this a set or a spade draw?

its Kx enough that this play is money in the bank

Thought so, thanks.
I just hate 3-betting all-in on the flop with an overpair OOP. I always just tell myself here that my hand isnt getting any better with another card, and I might fold out the flush chaser if I wait to donk the turn.

Unless you know villain really well, this hand plays itself.

K45 two suited figures to be a great board to felt Aces.

raise more preflop
