No reads but the LRR preflop is quite scary so I didnt cap. On the turn I no see that a lone Ax hand would raise me and 2 pair which is likely would also raise so I guess I 3bet. If I am up against AA, [img]/images/graemlins/frown.gif[/img] but I still have outs against a straight if I am behind.

Perfect river card, what is the default play? I now think a c/r would be better to try and trap the other player.
