[IrishPete]

villain is 70/10/2.5 over a small sample of 40~ hands.

bet/call turn against him, hes 70/10 hes gonna call you with like K3o and such.

as played im not folding although river overbets usually mean he missed his turn c/r...

What is the 205 number in his stats?

Please, please, please bet this turn.

River is pretty borderline, but I call because , but definitely bet this turn against a guy like this.

[IrishPete]

[thac]

Yeah I call this pretty much always.
