Don't let upset Bob you too much. I happen to know how Gambit Tiger
works and it is just great. No doubt I will try it myself for the next
Rebel.

Gambit Tiger entered 2 major tournaments and won them both without any
lost game. That is all what is important. I think Bob is just a bit
jealous. Perhaps I should send him a copy so he knows what he is talking
about instead of talking bullshit and humiliate the good work you have
done.
