I think you're annoyed for the fact that you would have taken the pot having seen what the other 2 had. I think the fold is a very reasonable move(any club or the board pairing has you dead) although I think you should maybe have thought about what you would do if you're faced with a reraise before putting in the extra £30. For me, once you put in that £30 you've got to be prepared to fire the rest in, if you werent, you couldve called and watch the blank come down on the turn, the 2 other guys were always still gonna stick it in on the turn and I think you would have too.
i cant see that calling to watch a danger card hit is a good move. if the board pairs or a club hits you (and probably rightly) will be put off. imo, push and charge em for their draws. if you are already beat fair enough, and if u get outdrawn ul.
I agree that pushing is probably the best option, but Bandit says he wasnt sure(and ultimately didnt) if he was willing to risk the bigger flush or another draw hitting. On the flop he couldve flat called for £10 and saw the turn(which was a complete blank) but instead raised £30, if he had thought that he might fold to a reraise for his £30 then, imo, its a viable option to flat call instead. I think if Bandit flat calls this and the blank hits the turn he'd feel safer pushing the rest in, going the extra £30 just to fold was the mistake here imo.
