Hi Mus -- One of the most useful tips I ever received was to keep the thumb below the middle of the neck. This forces you to stick your wrist out a bit further than seems natural, but it allows much more even and effective downwards pressure from the fingers (I don't think pressure from the thumb will help much, just as you had hoped). Dropping the thumb helps with bar chords, accuracy, and with long stretches. I find the optimal point for sounding the bar to be just behind the fret.
Best,
Phil
