Good to see a couple super ballers posting that they lose in non-SD.
This has been said many times, but I think the whole redline thing is WAY overvalued by 2p2 in general. Its quite obvious that its a product of the games you play in. My redline usually isn't consistent at all. I have won massive amounts without SD in HU games and also lost a lot without SD in HU games (obv villain dependent). The same applies to 6m, deep, cap, etc. The biggest fish in PLO games still overvalue hands in general, and against them, I fully expect to lose money in non-SD pots and still have a large edge. Even that isn't that simple. Some guys only overvalue hands preflop, but are pretty nitty postflop, and we will win without SD vs those guys, etc.
This is far from ground-breaking, but its still worth posting in these threads. Just beat whoever you are playing against IMO.
