115 to call a pot of 305. Less than 3:1 pot odds. You have a OESD with 8 outs, but 2 of those put the 3 flush on board so they may not be full outs and your backdoor flush draw isn't a draw at the nuts either. If you count your aces as full outs you might be able to give yourself a total of 9 or 10 outswhich equates to around 4:1 against or a 20% chance of making something out of your hand. I wouldn't even count 9 or 10 outs here, personally, which means the odds are actually worse. Even if you do make something with this hand it's not the nuts it's very possible you could lose more of your stack to a better hand. With M well over 20 you have plenty of time to make your move with a better hand. This is a fold.
