When I see them calling from the blinds with what I consider crap, open limping or playing suited crap from early position I label them fish and take there money at every chance. If they are open raising, folding the blinds and playing well from position I would play a little more cautious.
cheers guys for your response, i will update the thread after the game and hopefully tell you I won.
Jyms, suitedfish are always something i keep an eye out for. Lost sooo many big pots to fish playing crap cos it's suited...But also won a fair few aswell
