Pink Tutu Syndrome? (2 hands)

[Zoelef]

One of the upswings from my recent ass-straightening (poker-wise) is that I've made very few postflop plays that resembled anything like spewing chips. However, sometimes I go back through some of these hands and ask myself "Am I too timid with power hands, or am I suffering from MUB/Pink Tutu Syndrome?"
