Jeff Kroll Hands

Hello everyone,
I ended up in the top 100 in the robot championships once again, there were about 1700 competitors. I will be mixing in interesting hands from this competition in the following weeks.
I may be planning a special event over Labor Day weekend, depending on if I decide to go to Dallas for the regional there. More on that later.
Jeff Kroll is a Houston-area player and teacher who is a robot expert. He has accumulated close to 3,000 points playing robot bridge. He is no slouch when it comes to face-to-face bridge, either, as he won a Flight A Open Pairs and a Bracket I knockout event at regionals in 2017.
Jeff submitted these hands, he thought them interesting. If anyone else would like to submit hands, let me know and I can help with the BBO part if necessary.
