This is where I play the BBO free weekly instant tournament in real time. Its not meant to be "perfect", but to expose you to my thinking as I play the tournament real time. I suggest you play the tournament yourself before you look at the video.
Note: BBO Free Instant Tournaments open on every Friday and last till the next Friday. You have one week to play exactly the same tournament as I.

I think BridgeMaster is an excellent resource for improving your declarer play (and play in general). I suggest you select a suitable level, then go through each puzzle. If you fail, try it at least a few more times before you look at the solution.

I have been told that my explanations on youtube can make sense. So maybe you can try my youtube series instead (I have stopped after 37 videos).
