Do you think there is a dominant strategy in this game? If you leave one climber at base camp and take the other climber to the summit as fast as you can, then bring that climber down to a safe spot, then bring your second climber as high as you can get him before the end of the game....it seems that this strategy might be very hard to beat.
I'm curious about the strategy that wins most in your games.
I find that indeed you typically want to move one climber up faster than the other, but leaving the other literally at base camp until the first reaches the summit sounds like a losing strategy to me. You should sometimes advance your lower climber too, guided by tactical considerations like not wanting to advance your higher climber into a zone where bad weather is about to hit.
