They provide a "little" CPU, but allow it to burst to 2 ECUs. [1] The more expensive "small" instance offers 1 ECU. > Libego. It reported 27kpps and 10kpps per Ghz.

So, the micro instance would be too unreliable for a computer go competition. The small instance costs $0.085/hour ($0.12/hour on windows). So if each game takes 50 minutes (leaving 10 minutes for setup), and you play 10 games in your tournament, it will cost someone $0.85 ($1.20 for Windows-only programs) to enter the tournament. Not unreasonable; the cool thing is everyone could set up 10 small instances and all rounds could be played simultaneously :-) Downsides are that that is not much CPU, so level of play is going to be low.
