He folds pre flop taking 86,5:1!!! he had to call 20chips but he folds to his friend's 4bet shove . I never write names here but i think i have to do that now for these guys.
Certainly appreciate your frustrations. If you suspect collusion, report it to the site. Unfortunately posting it here won't help you unless ipoker sees it so best to just tell them directly. If you encounter issues with the site support or they don't handle a situation adequately you can also voice issues and detail problems in the internet poker forum which is better suited for these issues than the strategy forums are.
If you are unsure or wish to discuss a situation for further input, you may do as you've done here and post a situation without posting player IDs, but in general this should be reserved for non obvious issues that might cross over into the realm of strat discussion (IE discussing plays anonymously to figure out what might be suspicious or not among friends and posters is permissible but should be rare. if we posted every hand similar to the one you've posted above it would not be at all nuanced or rare).
Hope this makes sense- any questions or issues feel free to PM a mod.
