How can one see friendlies, whereby he doesn't need to buy in before playing. I am not too conversant with the SwC platform, and it makes me not to visit the site except when there is a tournament held there.
You are probably referring to "Freerolls" by saying "Friendlies". You can find freerolls in the Tournaments section. When you first login, if you are on pc, you are on the cash games section, back from there, and you are in lobby, then click on Tournaments from the side menu, and you will find all the available tournaments, including the freerolls. Freerolls don't give out high rewards, but they are good for practice. If you are either new to poker, or want to warm up and try what strategy works best for you, you should play freerolls every day.
I also have some chips which I wish to withdraw from there, but it is not up to the required minimum threshold for withdrawal, and how to use it and play game there is something else, and that has placed that reward pending ever since I got it.
Well, the minimum limit for withdrawals is 500 chips, which I also think should be reduced, but it's up to the team. However, if you can trust me, you can send the chips to me, and when I withdraw my chips I will withdraw yours as well and then send you the money. Send me a DM if you want to do this.
