Hey guys, I'm new to PLO and wanted to know why we are encouraged to Cbet smaller (half pot or so) multiway. Is it because the SPR gets smaller as we go multiway and we want to discourage raises vs. our entire range? Do we maybe find cheap bluff spots this way on lockdown boards where we look really strong since we're multiway? Is it harder to get action from mid strength made hands when we have a monster since we look so strong multi-way? Thanks, just curious what the main reason is.
