The first article states that the strategy introduced is for tournaments with 10 participants. I could not find in any article where multi-table strategy is introduced. Did I miss it? What, if any, is there a difference btw single table and multi-table tournaments?
Also, how does strategy adjust when it gets to 4, 3, or 2 players left?
Great questions. Sorry I can't help you out but would like to see guides for MTT and when it gets down to fewer players. I feel my game is strong with a full ring but once it gets to 3-2 players my game fails and usually end up 2nd or 3rd.
There is a great silver article about how to play a final table in a MTT. Should be available to you soon
