I think McLaren made the wrong strategy choice in qually. They seemed surprised that Alonso and Trulli got in front of them.
It's not the first time McLaren have gambled on strategy and had it backfire on them instead of just playing it safe, it's like they're trying too hard to be different to the others and come off as tactical geniuses.
McLaren in Brazil qualifying were gambling on an almost entirely wet race, it didn't turn out like that and when all the cars had to pit early on to change tyres this just totally negated their full tank of fuel advantage.
