A partner who counts and has sensible judgement and is pleasant is worth a thousand conventions at this point. Honestly, I've made the most leaps forward in my game when I could TRUST partner's unexpected lead/bid/discard/signal, and it either led me to the right play, or should have. Bridge is about the process of deduction, not the process of memorization. All that said, get the system down first. You can't make sense of what's going on if you don't understand the language.
