...the articles are just fine, also pushing preflop in this hand is just fine, the only thing is you play with maximum sized stack that is still playable according to the strategy and therefore standard raise would be a bit better than direct push, but it's very close. With any stack smaller than 24BB it's the best to push all-in directly preflop. So, you see following the strategy is never a mistake, but if you post hands here we'll try to give you more detailed info on specific hands.
About results, yeah, judges don't like them.
