well I think it was a good bluff anyway...

it happened last night at my home game. 6 people left, im 2nd big stack at table on the button.

I get dealt A-5s and call a reasonable raise from the SB (SB is semi loose player preflop). no other player calls.

Flop comes up rainbow K-4-9. SB bets quite big, so I immediately know he doesnt have kings (otherwise he definitely wood have gone all in). I call (because I decide Im going to bluff him oout as Im sure he has a pair 9s (a high pocket pair is outta the question).

Turn is some useless junk like a 7 . He bets and I raise, he calls.
River is Queen, he checks (he never check raises) so I bet out two thirds of my stack and he thinks it over for like half an hour then folds his 8-9s face up.

Normally I never show my hole cards but decided to show this time to put him on tilt! and yip he went on tilt.

I love a successful bluff.
