PF: One of my favourite hands ! I make it 3BB+1 for each limper.
Flop: Gutshot, 2 Overs, BDFD, but i was going to cbet anyway [img]/images/graemlins/wink.gif[/img]
Turn: Villain may have realised that i could c-bet with air here, so i decide to give it another shot. When he raises, i´m getting 1:5 so i call to see if the miracle Jack hits.
River: -&gt; I´m wondering if this hand was total spew.

After this hand, villain instantly leaves the table. Whenever villain does so, i think he was on a bluff. You think the same ?
