I have discovered a weak part of my game, when playing STTs and the table is down to 4 players I always seem to haemorrhage chips.

It seems that it's just down to luck whether I get through this phase of play or not.

Either I play too tight and just get blinded away OR I play too loose and just phiss all my chips away.

There must be a happy medium - but where is that medium?

Any info, articles or opinions on this phase of the game would be rally appreciated-
