So at the card game tonight & i am UTG with

, I Limp in with the BB player a known tight player who rarely gets involved without the goods. I make a statement of " notice I limped UTG you know what that means!!!" general banter tbh
Folds round to the small blind who makes it up, BB checks and we get

. blinds are 300 / 600 BTW
All check and a

on the turn, check from the SB, BB bets 1200 in to a 1800 pot, I give it the " thats unreal!, do you have a jack? " to our tight friend in the BB
SB folds.
River is

Now to tell you when I think i am at here, I know this chap bets with the goods & i think he either has a 10 or an Ace.
he bets 2500...
I now give it my best Paul Newman impression, big proper acting jobbie & follow it up with " thats so sick if you have a Jack" I pause for a few more seconds & say "OK OK "
He the asks " what does that mean?"
I reply "it means i need more time..."
A few more seconds pass and i declare I don't believe him and raise it up to 5000 more on top of his 2500.
He contemplates a reraise and thinks the better and flat calls..
I flip over my jack as he shows his 10.
Now the interesting part is now. He the accuses me of cheating... I am astonished! TBH i am thinking i worked for the call and the extra chips, i did not get unfriendly or do the whole Tony G thing, I simply pretended not to have a jack to induce the betting and get a call.
So was it cheating/Stroking or just normal speech play you would find in most card rooms?
