I"m glad the thread stirred up some debate, as I was confused myself as to the procedure...
My primary reason for entering the HORSE event is that it isn"t an event you often (ever) get to play live, and if I was shortstacked in day two I really wouldn"t appreciate being told that I couldn"t play, even if I wanted to retain my seat.
My favorite suggestion so far is to stagger the stat times on the sunday. Either pushing the HORSE event out, or bringing the ME in an hour or so.
But it is still very chip stack dependent and could have a massive impact on strategy, especially towards the end of day 1.
For example, if I am short-stacked late on the friday and know that I cannot enter the HORSE event if I am still alive on day 2, then I will be shipping it much lighter than usual, taking the view that I will either bust or double-up a few times and make it worth my while. If I know I will get an hour or so"s play on Sunday then I will play more "normally", use the first hour of day 2 to see how things develop but also have a full day in between to assess whether I will release my HORSE seat or not - primarily based on how much life I believe I have left in the ME. That would be a much better situation IMO.
If we are allowed to multi-table then again it depends on stack sizes in both competitions, but I would probably select to play certain rounds in HORSE (where I feel I may have an edge). Of course, for this to work the tables would need to be located fairly close - if they decide to play one event at one end of the venue and the other at the opposite side then such a strategy would be nearly impossible.
It will probably be academic anyway, as I will likely be knocked out before the first break on day one
but we need clarification one way or another as the last thing I want to happen would be losing focus at the end of day 1 as I am confused about the implications of my play....
Another idea (most will think this is rubbish I"m sure)...if we have to forfeit the HORSE seat, ensure there is a HORSE side-event - perhaps a SNG - running in parallel but a bit later, so players still get the chance to experience it in a live setting.
