I know a lot of MTTers use a 2.5x pre raise and I'm getting used to that. But when would you migrate over to a 2.1x sizing? Also guess you're not supposed to bet 2/3 of pot like cash. Is 1/2 pot size betting still large for MTT on rivers? I have incorporated 1/3 sizing on flop. But not sure what size for turn and river?
As you can prob tell I'm mostly a cash player. I've been told by a few people to really stick to one or the other as not too many are good at both cash and MTT. I have a decent win rate in cash.
