I do not have the hand history but I remember the hand well. Good bluff or sucidal? Just after the first break in a 180 person sitn go, A10 off 3 off the button, folded to me. I have just over 4K chips giving me a decent though not great stack. 150/75 blinds. The cutoff and the button both have me covered, the button has 6K in chips and calls, the blinds fold.

Flop of 9C 8S 5C Pot :1100 I make a standard 500 chip continuation and he smooth calls

Turn 9 of D Now is basically when I have to decide how far I want to go with the hand, I can check and either check it down or fold. He has seemed weak so far, the most obvious possiblitys is an flush draw or J10. Well I decide to bet half the pot again for 1000 leaving me 2000. He called.

River KS . I pushed and he folded. All draws missed.

Now all that said, was this a good bluff or was this just sucidal and I got lucky?
