Faulkdogg -

You need to change your game up when you're up against a large field.

If there are 3 hearts on the board, 5 players in the hand, and someone is betting aggressively - they just might have made a flush.

If there is an open end straight on the board - someone WILL have it.

In multi-way action, it pays to "chase". You need to chase better than your 'bad opponents'.
